2. Description and Operation
The EBDSPIR-AD PIR (passive infrared) presence detector provides automatic control of lighting loads
with optional manual control. It can be used on fluorescent and compact fluorescent lighting with 1-10V
analogue dimming ballasts. The unit detects movement using a PIR sensor and turns the load on. When
an area is no longer occupied the load will switch off after an adjustable time out period.
The detector can be used to control the light output of luminaires that are fitted with dimming ballasts. The
detector measures the overall light level in the detection area and calculates the correct output for the
luminaires, to achieve a preset lux level (maintained illuminance).
Two input terminals can be used to manually override the dimming levels and override the lights on or off.
An integral infra-red sensor in the unit allows the unit to be programmed using the optional DD-LCDHS
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.
The UHS user handset can be used to change output lux levels and override the lights on or off.
Two standard units are available:
EBDSPIR-AD - 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.
EBDSPIR-AD/ABS - absence detection:
The load is manually switched on. When the area is no longer occupied the load will automatically switch
off after the adjustable time period has elapsed. Note that the EBDSPIR-AD can be programmed to
absence detection using the programming handset.
In most applications the EBDSPIR-AD can be used with simple manual adjustment. However, the
EBDSPIR-AD unit has a comprehensive set of features that can be set using the DD-LCDHS handset.
Alternatively the units can be commissioned as follows:
On-site commissioning service - please contact our sales department for details.
Pre-commissioning service - the units will be despatched to site with the correct features set. The
part number will read EBDSPIR-AD/PRG followed by the project reference number. Please
contact our sales department for details.

3. Wiring & Fixing
1. Wire the products using the diagrams shown in section 5.
2. To switch from more than one position simply wire two or more units in parallel using the Live,
3. The detector should be sited so that the occupants of the room fall inside the detection pattern
4. Avoid direct sunlight entering the sensor.
5. Do not site within 1m of forced air heating or ventilation.
6. Do not site within 1m of any lighting.
7. Do not fix to a vibrating surface.
8. Mount using one of the two options above overleaf.
9. Connect the sensor via the terminal blocks. Live supply to the L terminal; load to the L/OUT
10. Use a small screwdriver to set the LUX level adjuster fully anti-clockwise, the time to minimum
11. Power the unit up—the load should come on immediately.
12. Vacate the room or remain very still and wait for the load to switch off (should take no more than 2
13. Check that the load switches on when movement is detected.
14. For dimming applications, set the light output level by using the LUX adjustment thumbwheel or
15. Select the time using the adjuster, fully anti-clockwise is the maximum.
16. Using the UHS or UHS3 infra-red handset: the override on button turns the unit on permanently;
Note: the above adjustments can also be made using the DD-LCDHS handset instead of the manual
adjusters. See section 4.

installed the smaller the detection range will be, subject to the parameters shown on the diagram.

minutes).
the handset. See section 4.5 for handset operation.
During operation the output level varies very gradually. However when the LUX level is
changed the unit automatically enters setup mode: in this mode the output level varies
rapidly. After the setup time the unit reverts to normal.
When adjusting the output, allow the output level to settle by changing very gradually.
To disable the maintained illuminance function completely, set the LUX level to maximum
(fully anti-clockwise).
the override off button turns the unit off permanently; the cancel button cancels the overrides.
When an override is selected an LED will flash inside the unit. The UHS handset can also be used
to set the lux levels—see Section 4.5
