Contact Sensor

Function overview

  • The Contact Sensor monitors the opening and closing of doors or windows.

  • The larger sensor is mounted on the fixed frame, while the smaller magnet is attached to the moving part (door/window).

  • When the door or window opens, the magnet separates from the sensor, triggering an internal magnetic switch that sends an alarm signal to the base station.

  • The Contact Sensor also communicates signal problems and low battery conditions.

LED indicator

In normal operation, the LED remains off except in the following cases:

  • The LED flashes when the Contact Sensor is triggered if battery status is low.

  • To confirm signal transmission, the LED flashes twice rapidly and stays on for 1.5 seconds once the base station has acknowledged the signal.

Battery

  • Uses 1 × 3V CR2032 lithium battery

    Battery status is reported to the base station via regular monitoring signals.

  • Low battery → app message + optional push notification, call, SMS, email

  • Battery replacement:

    1. Loosen the screw at the bottom of the sensor.

    2. Turn the device over and gently open the back cover with a flat-head screwdriver.

    3. Remove the old battery, wait 10 minutes, press the LED button five to six times to discharge residual power.

    4. Insert a new battery (+ side up).

    5. Re-attach the cover and tighten the screw.

Installation
1
Switch on

Remove the battery insulator → LED flashes for 30 seconds (warm-up phase). The sensor is now ready for use.

2
Registering with the app

Follow the instructions in the app to add the Contact Sensor.

Placing/Mounting the Contact Sensor
  • Mount the Contact Sensor on the fixed door/window frame, and the magnet on the moving part (door/window).

  • Maximum distance between magnet and sensor when door is closed: 15 mm.

  • Mount using screws/wall plugs or the included double-sided adhesive pad.

Congratulations! The installation of your Contact Sensor is complete.
