CP EBDHS-PRM-LT30 Product Manual

Overview

The EBDHS-PRM-LT30 PIR (passive infrared) presence
detector provides automatic control of lighting loads with
optional manual control. The EBDHS-PRM-LT30 is a high
sensitivity PIR detector suitable for high bay applications,
such as warehouses and factories, and where high
detection sensitivity is needed

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.

All functionality is fully programmable using an IR handset.

Product Guide

PIR 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

Measures the overall light level in the detection area

Status LEDs
The LED flashes Red to indicate the following:

Power Input & Switched Output Connector

Used to connect mains power to the unit and to connect a
switched load.

Switch Input Connector

Two input terminals can be used to manually override the
lights on or off (not fitted to EBDHS-PSUR-PRM).

Alignment marks

The sensor head
has 4 alignment
marks. These
correspond to the
4 outer passive
infrared sensors
under the lens.
Use these marks
to align with aisles
and corridors to
ensure the best
detection
characteristics.

Masking

The EBDHS-PRM-LT30 includes two clip-on masking shields to allow for precise masking of the detection shape.
The masks can be easily shaped to produce detection patterns suitable for applications such as aisles and corners and

for narrowing the detection diameter.

Important note. Ensure all infra-red (IR) programming is completed before affixing the masking shields to the

detector.
The masking shields may impair the light sensor and IR sensors by covering them. Ensure
correct operation before completing commissioning.
