Are ALPENLUFT smoke detectors quality tested?
When it comes to fire protection, there can be no compromises! ALPENLUFT smoke detectors undergo rigorous quality testing. Our devices are TÜV Rheinland certified (test mark number 1111280065) and CE tested according to EU standard EN14604. With ALPENLUFT, you are purchasing reliable safety!
What are the advantages of an optical sensor
Our smoke detectors have a highly sensitive optical sensor that recognises smoke particles in the air by using optical (light) signals. This technology is used in so-called photoelectric smoke detectors.
How it works:
- Integrated light source: There is a light source inside the smoke detector that emits light in a specific direction.
- Reflection by smoke particles: When smoke enters the smoke chamber of the detector, the smoke particles scatter or reflect the light.
- Detection by sensor: An optical sensor recognises the scattered light beams. As soon as a certain amount of light is detected, the smoke detector triggers an alarm.
Advantages of optical sensors:
- They react quickly to smouldering fires where there is a lot of smoke but little flame.
- Suitable for living areas such as bedrooms and hallways.
- They are less susceptible to false alarms caused by steam or cooking odours compared to ionisation smoke detectors.
How loud are the detectors in the event of an alarm?
The volume of our detectors is over 85 dB.
We therefore strongly recommend wearing hearing protection when carrying out a test alarm.
What smoke detector models do you offer?
Our smoke detectors are available in 3 variants:
SMART Smoke Detector Interlinked with smartphone app
The SMART Smoke Detector Interlinked can be operated via smartphone app using the WiFi Gateway. You can integrate up to 40 detectors into one network.
The range is up to 200 m between individual detectors and up to 400 m between the detector and the WiFi Gateway.
In addition, this model features a practical mesh forwarding.
Smoke & Heat Detectors Interlinked
With the ALPENLUFT Smoke & Heat Detectors Interlinked, up to 30 detectors can be integrated into one network. With this model, you can also switch between smoke and heat mode (ideal for kitchens, bathrooms, or rooms with smoke or steam development).
The devices can be interconnected directly on the units or via the convenient ALPENLUFT remote control.
ATTENTION! The SMART Smoke Detector Interlinked cannot be interconnected with our Smoke & Heat Detectors Interlinked, as the models communicate on different radio frequencies.
Standalone Smoke Detector
The ALPENLUFT Standalone Smoke Detector cannot be interconnected. In case of an alarm, these detectors do not transmit the signal to other devices.
How many detectors do I need?
To begin with, you should equip all bedrooms and connecting corridors. An alarm should be installed in every bedroom.
Install an alarm in the stairwell and on each floor of the house.
If the area to be monitored is larger than 60 m², you must install several smoke alarms.
Please note that our Smoke Detector Standalone model should not be installed in areas with high humidity, e.g. in bathrooms, garages or kitchens, to avoid false alarms.
Our Smoke & Heat Detector Interlinked can be operated in both Smoke and Heat Mode. In heat mode, high humidity is not a problem.
Does the LED on the detector blink regularly? Are the smoke detectors suitable for bedrooms?
The LED does not flash in Standard Mode. This is why our smoke detectors are also suitable for bedrooms.
In Sleep Mode (after an alarm), the LED flashes every 8 seconds. The smoke detector automatically resets to Standard Mode after 10 minutes.
Can ALPENLUFT smoke detectors be integrated into a Wi-Fi network and controlled via an app?
Yes, we offer the SMART Smoke Detector Interlinked. It can be operated via smartphone app using the WiFi Gateway.
What is the EU standard for smoke detectors?
The EU standard for smoke detectors is EN 14604. This standard specifies the requirements, test methods, and performance characteristics for the design and function of smoke detectors used in residential buildings and similar applications.
What does a 10-year battery in a smoke detector mean?
Our smoke detectors are powered by a non-replaceable 10-year battery. It is included and already installed in the device. The battery has a lifespan of 10 years, which corresponds to the maximum legally required lifespan of smoke detectors.
This means you don’t need to worry about regular battery changes. After the 10-year battery life expires, the smoke detector must be fully replaced in accordance with the law.
What happens after the 10-year battery life?
After the 10-year battery life expires, the smoke detector must be fully replaced in accordance with the law.
My smoke detectors have a replacement date that is less than 10 years in the future
Our smoke detectors are manufactured in larger production batches. The legally required replacement date (“Date of Replacement”) is always set based on the production period + 10 years – not the individual purchase date. As a result, a detector may have been produced several months before shipping and therefore display an earlier replacement date.
However, this does not mean that you have a shorter usage period:
- The 10-year battery life only begins from the moment you activate the detector.
- You therefore receive the full 10 years of functional lifetime – regardless of the printed replacement date.
- The replacement date serves only as a guideline for the mandatory replacement and is based on the production date for regulatory reasons.
If we were to ship only devices labeled with exactly today’s date plus 10 years, we would have to produce each batch precisely day by day – which is logistically impossible and would lead to extreme delivery delays. This is why all manufacturers in this industry operate this way, including major brands.
Can I also install the detectors in rooms with high humidity?
To avoid false alarms, our Standalone Smoke Detector and our SMART Smoke Detector Interlinked should not be installed in areas with high humidity, such as bathrooms, garages, or kitchens.
Our Smoke & Heat Detectors Interlinked can be operated in both smoke and heat mode. In heat mode, high humidity is not a problem.
Do the detectors require a specific ambient temperature to function correctly?
We recommend a temperature range between 0°C and around 40°C.
At temperatures below 0°C, the detector may trigger false alarms or the battery could be damaged.
What is Sleep Mode?
If the detector is in alarm mode, you can silence the alarm for 10 minutes by pressing the test button. The red LED will now flash every 8 seconds, indicating that the alarm is in silence mode.
The silence mode function should only be used in case of a known false alarm (see next paragraph). The smoke detector will reset automatically after 10 minutes. If combustion particles are still present in the air after this period, the alarm will be triggered again.
With our SMART Smoke Detector Interlinked, you can also activate silence mode directly in the smartphone app:

A false alarm can be triggered by dust, cooking fumes, or other non-hazardous sources.
Please also refer to the user manuals for the SMART model, the Smoke & Heat model, and the Standalone model.
Can a false alarm be triggered by cigarettes, shishas or vapes?
Our smoke alarms also react to smoke from cigarettes, shishas and vapes.
The smoke from burning cigarettes and the vapour from shisha contains small particles that can trigger the operation of smoke alarms.
The same applies to vapes, although the risk is lower than with cigarette or shisha smoke. Vape vapour contains fewer soot and ash particles, as it essentially consists of vaporised liquid and does not contain combustion products such as tobacco smoke. Nevertheless, in large quantities and in small, poorly ventilated rooms, vapes can also cause an alarm.
Whether an alarm is actually triggered also depends on the amount and concentration of cigarette smoke. Heavy, dense smoke in a small room is very likely to exceed the sensitivity threshold. Low levels of smoke or larger, well-ventilated rooms often do not trigger an alarm.
However, you can avoid this with our Smoke & Heat Detector Interlinked model, by operating it in Heat Mode.
Heat Mode is intended for rooms such as bathrooms, kitchens, garages or rooms with a fireplace, where smoke or vapour would otherwise trigger a false alarm.
You can find more information about heat mode here:
What is the purpose of Heat Mode?
What is the purpose of Heat Mode?
Our Standalone Smoke Detector model and our SMART Smoke Detector Interlinked should not be installed in areas with high humidity, such as bathrooms, garages, or kitchens, as this may trigger false alarms.
Our Smoke & Heat Detector Interlinked can be operated in both Smoke and Heat Mode.
A simultaneous operation in smoke and heat mode is not possible and also not practical, since the heat mode is intended for conditions where the smoke mode would trigger a false alarm.
In Heat Mode, high humidity is not a problem.
The heat sensitivity is approx. 54~72℃, above which an alarm is triggered. It is difficult to specify an exact value here, which is why we can only specify the trigger temperature in this range.
You can switch between Smoke and Heat Mode at any time.
To switch between Smoke and Heat Mode, please press the test button three times. If the detector has already been mounted on the ceiling, you can also use a broomstick to do this.

- The LED flashes red once: Smoke Mode has been activated.
- The LED flashes 1x green: Heat Mode has been activated.
Please also watch the following video:
Can the smoke detectors be tested with test gas?
Yes, our smoke detectors can be tested with test gas.
We use the RMT spray for this purpose:
Buy RMT test spray
Spray the detector from about 20 – 30 cm away for at least 10 – 15 seconds, as shown in the video here:
Test Smoke Detectors with Spray
What is the height of the smoke detectors?
Our Smoke & Heat model and our Standalone model have a diameter of 120 mm and a height of 24 mm without the mounting plate. Including the mounting plate, the total height is 31 mm.
Our SMART model has a diameter of 80 mm and a height of 30 mm. The mounting plate does not affect the height of this model.
What is the RAL color code of the smoke detectors?
Our smoke detectors have the RAL color code "9003 Signal White".
Smoke detector maintenance
Please note that smoke detectors must be cleaned at least once a month to remove dust and dirt and ensure proper operation. A test alarm should also be carried out once a month.
Use a vacuum cleaner or a soft duster for cleaning. Vacuum all sides of the smoke detector.
The smoke detectors perform a silent self-test every 60 seconds. However, it is still recommended to test your smoke detectors at least once a month to ensure they are functioning properly.
To test the alarm function of the Standalone Smoke Detector model and the Smoke & Heat Detectors Interlinked, press the test button once. You will hear 2x three alarm tones while the red LED flashes. The detector will then stop automatically. The detector is functioning properly.
To test the alarm function of the SMART Smoke Detector Interlinked, press and hold the test button. You will hear 1x three alarm tones while the red LED flashes. The detector will then stop automatically. The detector is functioning properly.

How do I install a smoke detector?
Each smoke detector should be installed in accordance with the manufacturer's instructions. In principle, smoke detectors should be installed on the ceiling and preferably in the centre of a room. In the case of networked smoke detectors, it must also be ensured that all devices are properly connected to each other.
Please also refer to the user manuals for the SMART model, the Smoke & Heat model, and the Standalone model.
Where and at what distance should I install the smoke detectors?
Smoke, flames, and heat spread horizontally after rising to the ceiling. Therefore, install the detector in the center of the ceiling.
If the detector cannot be installed in the center of the ceiling, install it at least 300 mm away from corners.
If the detector is installed on a side wall, it should be mounted at least 100 mm below the ceiling.

If the area to be monitored is larger than 60 m², multiple smoke detectors must be installed. Please install the detectors at a distance of 150 cm from each other.
If the wall or ceiling is sloped, the detector must be installed at least 500 mm away from the highest point in the room.

Please also refer to the user manuals for the SMART model, the Smoke & Heat model, and the Standalone model.
Is it possible to install the smoke alarm vertically on a wall instead of on the ceiling?
Our smoke alarms must, according to EN 14604, be installed horizontally on the ceiling. Vertical installation on a wall is not permitted, since smoke rises upwards and the alarm can only trigger reliably and in compliance with the standard when mounted on the ceiling.
Should I opt for mounting with adhesive strips or screws?
Please also refer to the user manuals for the SMART model, the Smoke & Heat model, and the Standalone model.
What distances do the drill holes need to be if I want to fasten my detector with screws?
The mounting plate of our Smoke & Heat Detectors Interlinked and Standalone detectors has a diameter of 12 cm.
The distance between the drill holes in the mounting plate is 6.9 cm – 7.1 cm, as the cutout has a slotted shape:
The mounting plate of our SMART Smoke Detector Interlinked has a diameter of 7.4 cm.
The distance between the drill holes in the mounting plate is approx. 4.8 cm:
Can the smoke detectors be fitted with a magnetic holder?
Although our detectors are designed for adhesive or drill mounting, they can also be attached using a magnetic holder. In this case, the detector should then be glued to the magnetic disc.
However, as these discs are not specially made for our smoke detectors, we cannot guarantee that the discs will hold and accept no liability in the event of damage.
Magnetic holders are not included in the scope of delivery.
How do I switch my smoke detectors on and off?
Smoke & Heat Detectors Interlinked and Standalone Smoke Detector
To turn on the Smoke & Heat Detector model and the Standalone Smoke Detector model, press and hold the test button.

You can also do this using a broom handle if the detector is installed in an elevated position.
Sometimes the devices may take a little longer to turn on. Hold the test button for up to 30 seconds, or until you hear the signal described below.
After switching on, the detector emits a short beep and the LED flashes once in red.
Please also watch the following section in our instruction video:
Switching off:
Press and hold the test button again for up to 30 seconds. After switching off, 2 beeps sound and the LED flashes twice in red.
Please also watch the following section in our instruction video:

Press the blue safety switch twice briefly in succession, then press the test button once briefly. The green LED will now flash. Press the test button again and hold it until the LED turns off. The detector is now switched off. You can verify this by pressing the test button again – the device will no longer emit any sound.
Please also watch the following section in our instruction video:
How often should I test my smoke alarms?
The smoke alarms test themselves silently every 60 seconds. However, it is recommended that you test your smoke alarms at least once a month to ensure that they are working properly.
You can find out how to carry out a test alarm here:
Does the smoke detector have a test button? Where is it located?
For our Smoke & Heat Detector model and Standalone Smoke Detector model, the entire surface is the test button. Press and hold it to perform various functions.

On the SMART Smoke Detector Interlinked model, the test button is located on the top center of the device.

How do I carry out a test alarm?
No open flames! Do not use open flames or cigarettes for testing. These could damage the device or cause a fire. For sensor tests, use only approved smoke detector test sprays!
More information in this article:
Can the smoke detectors be tested with test gas?
Please make sure to wear hearing protection during the test, as the alarm can damage your hearing!
Test alarm: Smoke & Heat Detectors and Standalone Smoke Detector
Press the test button on the activated smoke detector once.

Three alarm tones will sound twice while the red LED flashes. The detector will then silence itself automatically.
With the Smoke & Heat Detector, all other detectors in the radio network will also sound.
Please also watch the following section in our interconnection video, which shows how a test alarm is performed:
Test alarm: SMART Smoke Detector Interlinked

Select the detector in the ALPENLUFT Connect App and tap Test.

Please also watch the following section in our instruction video:
Can I test the functionality of smoke detectors using cigarettes or incense sticks?
Important note:
A cigarette or incense stick is not a suitable test for an optical smoke detector. These devices respond to a specific smoke density and particle concentration in the measuring chamber. Cigarette smoke usually disperses too quickly and is often not sufficiently concentrated to trigger an alarm – especially in well-ventilated rooms.
How to correctly test an optical smoke detector:
Function test via the test button (recommended)
Press the test button on the device to trigger a test alarm. You can find instructions in this article:
How do I perform a test alarm?
→ If the alarm sounds, the electronics, sounder, and power supply are all functioning correctly.
Test with approved smoke detector test spray
For a realistic sensor test, we recommend using a dedicated smoke detector test spray (available at hardware stores or online).
→ The spray simulates smoke at a standard-compliant concentration and reliably triggers the alarm without damaging the device.
You can find instructions in this article:
Testing smoke detectors with spray
Important!
Do not blow continuous smoke directly into the device or hold open flames underneath it. This can contaminate or damage the measuring chamber.
How can I remove a smoke detector?
You can easily remove the detector by turning it carefully to the left. You may have to turn it a little harder to disengage the detector.

How many SMART Detectors can I network?
You can connect up to 40 devices of our SMART Smoke Detector Interlinked in one network.
Please also refer to the section How do I connect my SMART Smoke Detectors Interlinked?.
How do I network my SMART Smoke Detectors?
Interconnection via app
We recommend using the WiFi Gateway together with the ALPENLUFT Connect App for interconnection and operation.
A detailed guide can be found in the section "Add smoke detector" in our App quick start guide.
Once you have added the SMART Smoke Detector Interlinked to the app, all devices are additionally interconnected via radio. This is especially important in case of a WiFi network failure, ensuring that all detectors in the network will still sound an alarm.
Please also watch the following section in our instruction video:
Interconnection on device without app
If you want to operate the SMART Smoke Detector Interlinked without a WiFi Gateway and smartphone app, we still recommend interconnecting the detectors via radio. This ensures that all devices will sound an alarm in case of an emergency.
Select one device as the host detector and press the test button 4 times quickly in succession.
Then press and hold the button after the 4th press.
The green LED of the host detector will start flashing for about 1 minute.
Press the test button on the other devices 3 times quickly and hold the button after the 3rd press.
The green LED will flash and then turn off, followed by a short beep.
You can check the interconnection by pressing and holding the test button for 1 second.
All detectors in the network will now sound. The detectors are now interconnected.
Please also watch the following section in our instruction video:
What range do the SMART Smoke Detectors have?
The SMART Smoke Detector Interlinked offers a wireless range of up to 200 m between individual detectors and up to 400 m between the detector and the WiFi Gateway.
An exact statement regarding the range cannot be made, as different materials have different permeability.
In addition, the devices feature mesh forwarding. This means that the detectors and the gateway can relay signals between each other. As a result, not all devices need to be within direct range of one another. This allows even larger apartments or houses with multiple rooms and floors to be reliably interconnected.
You can of course check whether the range meets your specific situation and requirements by performing a test with the detectors. You have a 14-day right of return.
What is the repeater function / mesh forwarding?
Our SMART Smoke Detector Interlinked features mesh forwarding. This means that the detectors relay wireless signals to each other. As a result, not every smoke detector needs to be within direct range of the gateway or all other devices – the signal can be forwarded via other detectors.
This offers several advantages for smoke detectors:
-
Greater range: Even distant rooms or additional floors can be reliably connected.
-
More stable connection: Walls, ceilings, or long distances can be bridged more easily.
-
Higher safety: If one detector is triggered, the signal is relayed through the network so that all detectors in the home alarm simultaneously.
-
Flexible installation: Devices can be installed where they are most effective for safety – not just where the wireless signal is strongest.
This ensures that an alarm is quickly and reliably transmitted throughout the entire home.
Can I deactivate my SMART Smoke Detector Interlinked in the app?
For safety reasons, the alarm function cannot be deactivated in the app. To do so, you must switch off the detector directly on the device, as shown in this video:
How often and on which frequency band do the SMART Smoke Detectors communicate with each other?
On which frequency band do the SMART Smoke Detectors communicate?
The SMART Smoke Detectors communicate via Sub-1GHz at 868 MHz. This frequency offers long range and excellent wall penetration at very low energy consumption.
During normal operation, there is no continuous communication. A connection is only established in two cases:
- Heartbeat: Once every 24 hours, each smoke detector sends a status signal to the WiFi Gateway.
- Alarm: In the event of a fire alarm, communication is triggered immediately.
What is the heartbeat and what is it used for?
The heartbeat is an automatic signal that each smoke detector sends once a day to the WiFi Gateway. It confirms to the system that the device is active and reachable.
The 24-hour cycle starts from the moment the detector was added to the WiFi Gateway.
When is a device considered "Offline"?
If the WiFi Gateway does not receive a signal from a smoke detector for two consecutive heartbeat cycles, the device is marked as offline in the Connect App.
This corresponds to a period of approx. 24 to 48 hours without a response.
Why was my heartbeat interval reset?
The heartbeat interval is reset whenever the WiFi Gateway is powered off and back on. After a restart, the 24-hour cycle begins again for all detectors.
Can I integrate the SMART Smoke Detectors Interlinked into my smart home system (e.g. Home Assistant, Google Home, or Alexa)?
The radio protocol of our SMART Smoke Detector Interlinked is proprietary, meaning it is intended only for interconnection between the detectors themselves and the WiFi Gateway.
This means you cannot integrate the alarm signal directly into a smart home system (Home Assistant, Google Home, Alexa, etc.).
Can I interconnect the SMART Smoke Detectors Interlinked with the Smoke & Heat Detectors Interlinked?
The SMART Smoke Detectors cannot be interconnected with our Smoke & Heat Detectors, as the models operate on different radio frequencies.
Does the SMART Smoke Detector have a heat mode?
The SMART Smoke Detectors Interlinked and Standalone Smoke Detectors do not have a heat detection function and are purely optical smoke detectors.
For this function, you would need to purchase the Smoke & Heat Detectors Interlinked, where you can switch between smoke and heat mode.
I have a "tampered" warning in the Connect app
If you remove the mounting plate of a smoke detector, a tamper warning will appear in the app:

This is a safety feature: Without the mounting plate, the detector can be switched off using the blue button on the back:
As soon as you reattach the mounting plate to the detector, the “tampered” warning for the affected device will disappear automatically.
Please also watch the following section in our instruction video:
I cannot connect my WiFi Gateway to my WiFi network in the app.
If you cannot connect your WiFi Gateway for the SMART Smoke Detector Interlinked to your WiFi network in the ALPENLUFT Connect smartphone app, there may be several reasons.
Please also refer to our gateway help. It covers the issues and solutions in detail.
Frequency
Our gateway only works with WiFi networks based on 2.4 GHz.
5 GHz is not supported for technical reasons.
WiFi password
Please note the following limitations when connecting your WiFi Gateway to your WiFi network:
- WiFi name (SSID): max. 32 characters
- WiFi password: max. 63 characters
This is a technical limitation of the WPA/WPA2 protocol and applies to all compatible devices — not just our products.
If your password is longer than 63 characters, the device cannot connect properly. Please shorten the password in your router settings to a maximum of 63 characters.
WPA2
If the connection with the gateway still does not work, set your WiFi network to WPA2 during the connection process.
This setting must be changed in your WiFi router settings — not on the gateway itself.
- Open your router interface in your browser, for example:
192.168.0.1,192.168.1.1,192.168.2.1,10.0.0.1
If you are using a FRITZ!Box, try:192.168.178.1,169.254.1.1,fritz.box - Navigate to a section such as WiFi, Wireless Settings, or Security
- Set the encryption or security mode to WPA2
Once the gateway is successfully connected to your WiFi network, you can restore your previous security settings.
Can I use the Connect app on multiple smartphones / share my SMART Smoke Detectors Interlinked with other users?
You can log in to the ALPENLUFT Connect App on multiple smartphones using your user account.
Alternatively, you can also share your devices with other users, who will then be able to control the detectors and receive alerts in case of an alarm.
How can I reset my WiFi Gateway to factory settings?
If you want to reset your WiFi Gateway to factory settings, for example due to persistent connection issues or if you want to connect it to a new Connect App account, please follow these steps:
Press the network button 10 times:
The LED will now flash blue for 5 seconds:
After that, the device is back in network mode and the LED will flash green again:
The reset gateway has been removed from the Connect App. All smoke detectors connected to the gateway have also been removed from the app.
If connection issues persist, we recommend checking our Gateway Help.
There you will find solutions for the most common causes.

- How do I switch between Smoke & Heat Mode?
- Can I interconnect the Smoke & Heat Detectors Interlinked with the SMART Smoke Detectors Interlinked?
How many Smoke & Heat Detectors can I network?
You can connect up to 30 devices of our Smoke & Heat Detector in one network.
If you would like to operate more devices, you can easily create several networks.
Please also watch the following video:
How does the wireless connection work with smoke detectors?
Radio-networked smoke detectors communicate with each other wirelessly. If a detector detects smoke and sounds the alarm, it sends a signal to the other detectors in the network, which also sound the alarm. This ensures that all residents in the house are warned, regardless of their position.
What range do the wirelessly networked Smoke & Heat Detectors have?
The range of our Smoke & Heat Detectors Interlinked is up to 100m, depending on the building structure. Mesh forwarding is not possible with this model.
However, an exact range cannot be guaranteed, as different materials have different permeability.
You can test this by carrying out a test with the detectors. You have a 14-day right of return.
For greater range, we recommend our SMART Smoke Detector Interlinked, which offers a wireless range of up to 200 m between individual detectors and up to 400 m between the detector and the WiFi Gateway.
In addition, the devices feature mesh forwarding. You can find more information about this in the following article:
What is the repeater function / mesh forwarding
How often and on which frequency band do the Smoke & Heat Detectors communicate with each other?
The Smoke & Heat Detectors only communicate with each other via 433 MHz in case of an alarm.
The Smoke & Heat Detectors cannot be interconnected with our SMART Smoke Detectors, as the latter operate on a different radio frequency (868 MHz).</p>
How do I know which device the alarm is coming from if I have several networked Smoke & Heat Detectors?
In the event of an alarm of our Smoke & Heat Detectors, you can easily locate the ‘source’ smoke detector from which the alarm originates. This emits its own alarm tone, which can be clearly distinguished from the other detectors. As soon as you mute it, the alarm is also silenced on all other devices.
You can find out exactly how to do this in the user manual under ‘Sleep mode’.
For safety reasons, this must be carried out manually directly on the ‘origin’ detector, as muting it remotely could lead to overlooking the hazard source from a distance.
How do I network several Smoke & Heat Detectors together?
Follow the instructions in the user manual under ‘Linking the smoke detectors’.
Networking the Smoke & Heat Detectors is also explained in detail in this video:
How do I network the detectors via remote control?
You can also network our Smoke & Heat Detector Interlinked via remote control.
You can find instructions on how to do this in the user manual under ‘’Linking the smoke detectors: Method 2 - via remote control‘’.
Please also watch this video:
The green LEDs on my Smoke & Heat Detectors don't not blink during the pairing process as described in the manual.
Please note that the green LED of the Smoke & Heat Detector Interlinked only lights up faintly. If you cannot see it clearly, please move to a darkened room for pairing.
Please also take a look at these articles about pairing:
Can I use several remote controls for my Smoke & Heat Detectors for one network?
No, you can only connect one remote control per Smoke & Heat Detector network.
Do I have to reconnect the Smoke & Heat Detectors after switching off/restarting?
No, new networking of your Smoke & Heat Detector is not necessary after switching off.
How do I add a new Smoke & Heat Detector to an existing network?
To add a new Smoke & Heat Detector to an existing network, you simply need to set any already interconnected detector – as described in the manual – to transmit mode and the new device to receive mode.
In this video, you can see exactly how it works:
If the detectors are mounted high up, you can also perform this using a broom handle.
How can I remove a smoke detector from the network?
To remove a Smoke & Heat Detector from the network, press the test button on the smoke detector twice in quick succession.
The green LED flashes for 60 seconds. The connection is then automatically disconnected. See also the following chapter in our networking video:
How do I switch between Smoke & Heat Mode?
Our Smoke & Heat Detector Interlinked model has 2 operating modes:
- Smoke Mode
- Heat Mode
The Heat Mode is intended for rooms such as bathrooms, kitchens, garages or rooms with a fireplace, where smoke or vapour would otherwise trigger a false alarm.
Simultaneous operation in Smoke and Heat Mode is not possible. You can easily switch between Smoke and Heat Mode by pressing the test button three times.
If the detectors are mounted high up on the ceiling, you can also do this with a broomstick.
If the detector then flashes red once, it is in Smoke Mode, if it flashes green once, it is in Heat Mode.
Please also take a look at the following chapter in our networking video:
Can I interconnect the Smoke & Heat Detectors Interlinked with the SMART Smoke Detectors Interlinked?
The Smoke & Heat Detectors cannot be interconnected with our SMART Smoke Detectors, as the models operate on different radio frequencies.
Smoke Detectors - Troubleshooting
- I cannot control my Smoke & Heat Detectors Interlinked via remote control
- My smoke alarm beeps for unknown reasons
- The LED on my detector blinks 8 times. What does that mean?
- What should I do if my smoke detector triggers a false alarm?
I cannot control my Smoke & Heat Detectors Interlinked via remote control
Please note that only our Smoke & Heat Detectors Interlinked are compatible with our Remote Control.
Our Smoke Detectors Standalone cannot be operated using the remote control.
You will need to establish the connection between the detectors and the remote control.
To do this, please first disconnect the smoke detectors. You can see how to do this here:
Disconnecting the wireless connection
If the detectors are already mounted on the ceiling, you can also perform this step using a broomstick.
Afterward, please reconnect the devices using the remote control as shown here:
How to connect your interconnected smoke & heat detectors using the remote control
My smoke alarm beeps for unknown reasons
Are the smoke detectors installed in a very cold room? Then it may happen that the smoke detector thinks the battery is empty at very low temperatures and gives a warning message.
It may also be that the error was triggered due to dirt or insects that enter the smoke detector and disturb its sensors.
Clean the smoke detector with a dry cloth or carefully vacuum it with a vacuum cleaner.
If this does not resolve the error, please contact us via email at office@alpenluft.org. We will be happy to assist you.
The LED on my detector blinks 8 times. What does that mean?
In Sleep Mode (after an alarm), the LED flashes every 8 seconds.The smoke detector automatically resets to Standard Mode after 10 minutes.
What should I do if my smoke detector triggers a false alarm?
If the detector is in alarm status, you can stop the alarm for 10 minutes by pressing the test button. The red LED indicator now flashes every 8 seconds, which means that the alarm is in Sleep Mode. The Sleep Mode function may only be used if a deliberate false alarm (see next paragraph) has been triggered. The smoke alarm resets automatically after 10 minutes. If there are still combustion particles in the air after this period, the alarm will be triggered again.
A false alarm can be triggered by dust, cooking vapours or other non-hazardous sources.
If the false alarm was triggered by known causes such as smoke or vapour (chimney, kitchen, bathroom or similar), you can switch our Smoke & Heat Detector Interlinked to Heat Mode to avoid this problem.
Please also refer to the operating instructions for the Interlinked and Standalone models.
Please also refer to the user manuals for the SMART model, the Smoke & Heat model, and the Standalone model.
