The sensor has a chip tuned wireless transmitter that communicates with a legacy 433 receiver such as, for example the ATS1230. The learn-in process of the sensor is identical to the process used with legacy sensors. Each sensor reports a unique ID code with each transmission. The sensor also reports the battery and transmitter condition (supervisory signal) to the panel every 18 minutes. This series of wireless motion sensors incorporate unique range gated radar technology allowing the installer to define a clear borderline of the radar range as the radar is used to measure distance between the sensor and moving objects. Effectively the end-user will get rid of any nuisance alarms generated by movements outside the detection range. Every motion sensor comes with four possible radar ranges selectable via jumpers allowing the detection range to be tailored according to the room where the motion sensor is installed. The radar operates on 5.8GHz frequency and will not interfere with any WiFi network. The optical mirror technology gives the advantage of gliding focus, which creates a volumetric detection curtain from floor level up to installation height resulting in a sensor that never loses track of the object. In these series we are using a dual element digital pyro generating two volumetric curtains for each of the nine curtain sets. These dual tech motion sensors generate an alarm depending on what both technologies – range gated radar and PIR – saw within their detection coverage. But our dual tech go beyond a simple “AND” function : it classifies the signals from each technology – range gated radar and PIR – to have the best alarm result without being sensitive for nuisance signal sources. This technology creates a uniform sensitivity in all course directions.
