2. Description and Operation
The EBDSPIR-HB-PRM PIR (passive infrared) detector provides automatic control of lighting loads with
optional manual control. This product has been specifically designed for the detection of movement in high
bay lighting applications such as warehouses and factories. It can be used on incandescent, fluorescent
and compact fluorescent lighting, and has the added benefit of being able to connect an external switch.
Two modes of operation are available:
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. If an external switch is connected, this
can override the lights off (after the detection time period has elapsed it will revert to automatic operation).
An integral adjustable photocell allows the lights to be kept off if there is sufficient ambient light.
Absence detection:
The load is manually switched on using an external switch. When the area is no longer occupied the load
will automatically switch off after the adjustable time period has elapsed. Pressing the switch again during
occupancy override the lights off (after the detection time period has elapsed it will revert to automatic
operation).
In both modes of operation a short button press turns the load on whilst a long button press turns the load
off.
An integral infra-red sensor in the unit allows the unit to be programmed using the optional DD-LCDHS-LR
programming handset. This gives complete flexibility over many of the operating parameters. Without the
handset, manual adjustments can be made to the sensitivity, lux and time settings using the controls on
the rear of the sensor head.

3. Wiring & Fixing
1. Wire the products using the diagram opposite.
2. To switch from more than one position simply wire two or more units in parallel using the Live,
Neutral and Switched Live wires only.
3. Position the sensor according to the detection pattern shown in section 5. Ensure that the marks
on the sensor line up with the direction of the aisle.
4. Avoid direct sunlight entering the sensor.
5. Do not site within 1m of forced air heating or ventilation.
6. Do not fix to a vibrating surface.
7. Mount using one of the two options overleaf.
8. Connect the sensor via the terminal blocks. Live supply to the L terminal; load to the L/OUT
terminal; Neutral to the N terminal on the green terminal block. External switch connections to the
switch terminal.
9. Use a small screwdriver to set the LUX level adjuster fully anticlockwise, the time to minimum (fully
clockwise) and the sensitivity to maximum (fully anticlockwise).
10. Power the unit up—the load should come on immediately.
11. Vacate the room or remain very still and wait for the load to switch off (should take no more than 2
minutes).
12. Check that the load switches on when movement is detected.
13. The LUX thumbwheel determines the ambient light level at which the lights turn on.
14. Select the time using the adjuster, fully anticlockwise is the maximum.
Absence detection
17. To use absence detection a retractive (momentary) switch must be connected between the 2
terminals on the diagram. Note that this will be switching mains voltage.
18. The unit ships with presence detection as default. To change to absence detection, press and
release the external switch 5 times within the first minute of power up. The LED will turn on solid
for 30 seconds to indicate absence mode has been selected.
19. To change back to presence detection, repeat the above procedure—the LED will flash for 30
seconds to indicate presence mode has been selected.
Note: the above adjustments can also be made using the DD-LCDHS-LR handset instead of the manual
adjusters or external switches. See section 4.
