Zamel Exta Life Wireless Motion Sensor with Magnetic Base RCR 21 I Powered by Batteries Optical Signalling of Sent Information Battery Charging Status Equipped

The RCR-21 sensor is a motion sensor (PIR) for radio control of the receivers of the EXTA LIFE system. It is characterised by a long range (up to 300 m outdoors) The motion sensor can work with an unlimited number of EXTA LIFE receivers. In time mode, it can turn system receiver on and off simultaneously for a certain period of time. The motion sensor is equipped with optical signalling of the sent information and the battery charge status. Powered by a battery With the built-in twilight switch, you can lock the sensor operation e.g. during the day. The sensor can work in two modes: as a motion sensor or as a motion sensor with twilight switch. The RCR-21 motion sensor communicates via radio transmission in the 868 MHz frequency band. The range can be increased by using a retransmitter or multiple REP-21 retransmitters.
