How to install the Calex Smart Smoke Alarm?
Frequently Asked Questions - 08/06/2026
Response Notice-Facile

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.

  2. Press and hold the control button on the Wifi Module for 5 seconds. The red indicator light will start flashing. The device is now in network mode.

  3. Follow the on screen prompts to finish installation. For more information, see our website: www.calex.eu A 'Di Di' sound sounds after successful installation.

If you get the notification the product only works on 2.4GHz networks you should change the WiFi-frequency of your network to 2.4GHz only in the settings menu of your router.

  1. Proceed to the section 2 for installing the device.
  2. Test each smoke alarm to be sure it is installed correctly and operating properly. See section 5.

§ 2 Installing the alarm

Be careful not to press the button on top of the alarm module unless you intend to do so. Pressing this button will cause the alarm to sound, the sound is very loud and may cause harm to your hearing.

1.1 Preparation

Determine how many alarms you need and where best to install them. See § 3 for more information on locations and § 4 for locations to avoid.

Before installing this product, check which plugs and screws are best suited for the surface.

2.2 Installation

Disconnect the alarm module from the base module by twisting the base module counter clockwise.

Alarm module > Disable the factory lock by pushing the lever clockwise.

Wifi module > Remove both plastic battery protection slips

After installing the alarm, attach the alarm module back on the WiFi module. Turn till you feel a click to ensure the Alarm Module is buckled in to place.

§ 3 Where to install smoke detectors

We advice at least one smoke alarm per floor.

3.1 As a minimum, smoke alarms should be located between sleeping areas and potential sources of fire such as living rooms and kitchens. In single storey homes with one sleeping area, a smoke alarm should be installed in the hallway, as close as possible to the living accommodation. To ensure audibility in bedrooms, no smoke alarm should be further than 3m away from any bedroom door. It may be necessary to install more than one smoke alarm, particularly if the hallway is more than 15m long. In single storey homes with two separate sleeping areas, a minimum of two smoke alarms is required, one outside each sleeping area. In multilevel or split level homes, as a minimum one smoke alarm should be installed on the ground floor between the stair case and any rooms in which a fire might start and on each

storey in circulation areas which form part of escape route(normally hallways and landings).

3.2 Additional alarms should be installed in bedrooms in anticipation of fires originating here, caused by faulty wiring. lights, appliances, smokers or other hazards.
3.3 For best protection, smoke alarms should be installed in every room in your home, apart from those listed in the Section 4

§ 4 Locations to avoid

DO NOT locate smoke alarms:

  • In turbulent streams of air such as near fans, heaters, doors and windows, etc. These can draw smoke away from the alarm.
  • In high humidity areas such as bathrooms and shower rooms as high humidity can trigger the alarm, or where temperature exceeds 39^ or falls below 5^ .
  • At the apex of an "A" frame ceiling. "Dead air" at the top may prevent smoke from reaching the alarm in time to provide early warning.
  • Less than 300mm (12 inches) from the wall when mounted on the ceiling.
  • In insect-infested areas. Tiny insects may affect performance.
  • In kitchens, boiler rooms, laundry rooms, garages. Combustion particles from cooking or car exhausts and dust and moisture could trigger the alarm.
  • In very dusty or dirty areas. Dirt and dust can build up and impair performance.

  • Within 300mm (12 inches) of light fittings or room corners.

  • In locations which would make routine testing or maintenance hazardous (e.g. over a stairwell).
  • On poorly insulated walls or ceilings.
  • Near objects such as ceiling decorations which might impede the path of smoke to the alarm.
  • Within 1500mm (5 feet) of fluorescent light fittings.

§ 5 Testing, maintenance and cleaning

This unit has been designed to be as maintenance-free as possible, but there are a few simple things you must do to keep it functioning properly:

5.1 Test each alarm at least once a week

Keep at arms length distance to the alarm during the test. The alarm is loud in order to alert you in case of an emergency and can be harmful to your ears.

Press the button (3) for a duration of two seconds. The alarm will sound a few short, loud beebs. Upon releasing the button, the sound will stop. The APP will receive a test signal after ten seconds.

5.2 Reset the alarm

If the test does not function properly, reset the alarm. Repeat the steps above.

Replace or return the alarm if the test does not function properly after completing these steps

5.3 Cleaning

Clean the smoke alarm at least once a month; gently vacuum the outside of the smoke alarm using your

household vacuum's soft brush accessory. Test the smoke alarm after cleaning. Never use water, cleaners or solvents since they may damage the unit.

If the smoke alarm becomes contaminated by excessive dirt, dust and/or grime, and gives unwanted alarms, replace the unit immediately.

§ 6 Function Description

Low voltage alarm: When the built in battery voltage of the smoke detector is below 2.7V, the red indicator light flashes once every 50 seconds, accompanied by a 'Di' sound. The app will (also) show a warning in the status bar.

Smoke alarm fault: The LED of the smoke alarm flashes once every 8 seconds and is accompanied by a buzzer. The App status displays an alarm fault.

If the device operates normal, the red LED indicator flashes once every 50 seconds.

WiFi Module batteries: The battery life of the base batteries is 3 years. If the power indicator in the App turns red you need to replace the batteries in the Wifi Module to ensure communication is maintained.

Problem: Smoke alarm is being triggered when the residents are cooking or showering

Solution: 1, clean the detector, refer to section 5 "Testing, maintenance and cleaning"; 2, install the detector to another place, refer to section 3 "Installation Location"

9. Limitations of some alarms

Smoke alarms have played a key role in reducing deaths resulting from home fires worldwide. However, like any warning device, smoke alarms can only work if they are properly located, installed, and maintained, and if smoke can reach the alarms.

  • Smoke alarms may not wake all individuals.
  • Smoke alarms cannot detect fires if the smoke does not reach the alarms. Smoke from fires in chimneys or walls, on roofs or on the other side of closed doors may not reach bedroom or sleeping area - especially if the bedrooms or sleeping area doors are closed at night.
  • Smoke alarms may not have time to sound before the fire itself causes damage, injury, or death, since smoke from some fires may not reach the unit immediately. Examples of this include persons smoking in bed, children playing with matches, or fires caused by violent explosions resulting from escaping gas.
  • Smoke alarms are not foolproof. Like any electronic device, smoke alarms are made of components that can wear out or fail at any time. You must test the unit weekly to ensure your continued protection. Smoke alarms cannot prevent or extinguish fires. They are not a substitute for property or life insurance.
  • Smoke alarms have a limited life. The unit should be replaced immediately if it is not operating properly. You should always replace a smoke alarm after 10 years from date of purchase. Write the purchase date on the space provided on back of unit.
