Overview
The EBDHS-DD-LT30 PIR (passive infrared) presence
detector provides automatic control of lighting loads with
optional manual control. The EBDHS-DD-LT30 is a high
sensitivity PIR detector suitable for high bay applications,
such as warehouses and factories, and where high
detection sensitivity is needed
Output Channel 1 comprises a mains voltage relay capable
of simple on/off switching, while Output Channel 2 provides
dimmable control of either DALI or DSI type ballasts.
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, or to implement a maintained
illuminance (daylight harvesting) system.
The flexibility of having two channels and two switch inputs
allows the following example scenarios:
Dim an outside row of luminaires whilst internal fittings
are switched
Provide absence detection for two separate channels
Maintained illuminance system with manual up/down
controls
All functionality is fully programmable using an IR handset.
