Comments
operation
The LRM2250 Infrared Ceiling Sensor is a
low voltage occupancy detector that works in
conjunction with the LCA power packs to control
lighting. The detector’s main function is to turn the
lights on or maintain the lights on while movement
is detected within the sensor’s range and to turn
the lights off when the space is left unoccupied.
A dedicated internal microprocessor continually
analyzes the room environment and adjusts itself
automatically. The internal timer and infrared
sensitivity are automatically adjusted. Once
installed, the LRM2250 does not require manual
adjustment or calibration.
The sensor uses a small semiconductor heat
detector that resides behind a multi-zone optical
lens. This Fresnel lens establishes dozens of zones
of detection. The sensor is sensitive to the heat
emitted by the human body. In order to trigger
the sensor, the source of heat must move from
one zone of sensing to another. Non-moving hot
objects will not cause the lights to turn on.
