Product Guide
The 796-2053 microwave presence detector provides
automatic control of lighting loads with optional manual
control.
The 796-2053 detects movement using a highly
sensitive microwave detector. This works by emitting low
power microwave signals and measuring the reflections as
the signals bounce off moving objects.
The output channel comprises a mains voltage relay
capable of simple on/off switching.
Functioning as a presence detector, the unit can turn lights
on when a room is occupied and off when the room is
empty. Optional settings allow lights to be turned off in
response to ambient daylight.
The 796-2053 has a unique adjustable sensor head
that allows the area of detection to be optimised for the
application.
All functionality is fully programmable using an IR handset.
Microwave Sensor
Detects movement within the unit's detection range,
allowing load control in response to changes in occupancy.
IR Receiver
Receives control and programming commands from an
IR (infrared) handset.
