Overview
The MPD-C-EXT 12-24V microwave presence detector
switch is designed to provide automatic control of lighting,
heating or ventilation loads. It detects movement using a
highly sensitive microwave detector. This works by emitting
low power microwave signals and measuring the reflections
as the signals bounce of moving objects. The MPD-C-EXT
12-24V is optimised for ceiling mounting applications to
give detection over long distances.
When movement is detected the load is turned on. When
an area is no longer occupied the load will switch off after
an adjustable time out period.
The internal light sensor provides additional energy saving
in lighting applications. When an area is occupied lighting is
only switched on when the level of natural light is below a
preset level.
Features
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.
Light Level Sensor
An integral adjustable photocell allows the lights to be kept
off if there is sufficient ambient light.
Presence detection
When movement is detected the load will automatically turn
on. When the area is no longer occupied the load will
automatically switch off after an adjustable time period.
