Question 2

How to install the Calex Smart Smoke Alarm?

Accepted Answer

Preparation: Before you begin, download the Calex Smart app (Google Play Store or Apple Store) and note your Wi-Fi network name and password. Important: the detector only works on a 2.4 GHz Wi-Fi network, not 5 GHz. If your router supports both bands, configure it to use 2.4 GHz only in your router settings.

Step 1 - Preparing the modules: The Calex Smart Smoke Alarm consists of two parts: the alarm module and the WiFi module. Separate them by turning the WiFi module counterclockwise. Remove the two insulating sheets (protective plastic) from the two 3V lithium-ion batteries. You will see the red indicator blink twice. Then, on the alarm module, push the factory lock lever clockwise to deactivate it (important: this step must be done before use).

Step 2 - Configuration via the app: Open the Calex Smart app. If this is your first use, create your account according to the instructions. Press the “add device” button (+) and follow the on-screen instructions to add this detector.

Step 3 - Activating network mode: On the WiFi module, press and hold the control button (the red button on top) for 5 seconds. The red indicator will start blinking continuously. The detector is now in network mode and ready to be paired with your Wi-Fi.

Step 4 - Wi-Fi pairing: Follow the on-screen prompts in the app to complete the pairing. Once successful, you will hear a double beep “Di Di”. If you receive a message indicating that the network is not operating on 2.4 GHz, go to your router settings and change the Wi-Fi frequency to 2.4 GHz only.

Step 5 - Physical installation: Before fixing the bracket, check that the supplied plugs and screws are suitable for your surface (ceiling or wall). Once the alarm module is still separated from the WiFi module, fix the bracket to the ceiling or wall with the supplied plugs and screws. Then, connect the alarm module to the WiFi module by turning it until you hear a firm click, ensuring a secure lock.

Optimal location: Install at least one detector per floor. Ideally, place it in hallways, between sleeping areas and potential fire sources (living room, kitchen). No detector should be more than 3 meters away from any bedroom door to ensure audibility. Avoid areas with turbulent drafts (fans, heaters, doors, windows), very humid areas (bathrooms, showers), kitchens, garages, dusty or insect-infested areas, and do not mount less than 300 mm from a wall or light.

Final test: Once installed, test the detector by pressing the test button for 2 seconds at arm's length. The alarm should emit a few loud beeps. The app will receive a test signal after 10 seconds. Test each detector at least once a week and clean the device with a soft vacuum once a month to avoid false alarms.
