When activated, the 1-way alarm remote control sends a signal to the actuators of the convenient electrical installation. The mobile device is powered by a button cell (CR2430). It can be assigned to the security function of the room manager, for example to trigger an alarm. If the 1-way alarm remote control is assigned to an actuator, it works in 'current surge mode'. An LED shows whether the signal has been sent, but also correctly understood and confirmed. The remote control can be easily attached to a key ring, lanyard or hanging clip (not included). An optional wall mount using a magnet is possible (110771, must be ordered separately). Battery included.
