Model 460B Active Infrared Intrusion Sensor
Model 460B is a long-range high performance, outdoor active infrared sensor for detection of walking, running and crawling intruders. The Model 460B consists of two 2 m (6.7 ft) columns – a transmitter unit, which is the source of invisible, active infrared emissions, and a receiver unit, which receives the signals, analyzes them, and detects intruders passing between the two units. Equipped with six high power infrared transmission beams, the Model 460B creates an undetectable protection zone of up to 100 m (328 ft).
The Model 460B cannot be covered, masked or blocked without causing an alarm, as multiple beams in each column are multiplexed uniquely between transmitter and receiver. Beam frequency channel selection allows multiple beams in a single column to operate without interference.
