These passive infra-red motion detectors will only work with the GSM/Wireless Alarm System. They will silently trigger the alarm when movement is detected. They can detect very small movements between 10-15m from the sensor, and have an intelligent in-built anti-error function that also performs a self-check every 1-2 minutes.
