GE Dual Technology Motion Detector

Precisionline Dual Technology Motion Sensor, Range-Controlled Radar, Passive Infrared Technology, Form C Relay, Tamper Contacts, Stealth Mode, Selectable Range Of 60, 70, 80 and 90 Feet With 90° Field-Of-View.

Using a sophisticated combination of precision controlled microwave and passive infrared technologies, the RCR-90 motion sensor is easy to install and use. A jumper switch allows quick selection of a precise range setting of 60, 70, 80, or 90 feet (18, 21, 24, or 27 meters). Coverage-on-Demand™ ensures the sensor detects objects in a specific area and ignores objects outside the covered range. The sensor determines the attributes of an object by calculating
its size and distance away. It works like sonar on a submarine, transmitting radar signals that “ping” the coverage area, then bounce back to the sensor on the same path. For high-security installations that require quicker detection, radar-only stealth mode is available.
