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).
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.
rugged module construction of the Model 460B allows beam sensors to be
adjusted independently into any configuration. The beams are equipped
with an automatic gain control (AGC) to compensate for infrared energy
and to self adapt to weather conditions while maintaining a constant
detection capability. An optional on-board heater provides operation in
all weather extremes.
The Model 460B utilizes high power
transmission beams for high probability of detection and reliability
against nuisance alarms. An integrated alignment system, with available
signal and LED indicators, allows a single installer to quickly and
easily set up and adjust the sensor.
