2. Description and Operation
The EBDSPIR-HB-DD PIR (passive infrared) presence 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 DSI or DALI digital dimming ballasts over
1 or 2 channels. 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 dimming channel of 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).
The switching channel of the detector can either be used to isolate the supply to the dimming ballasts
(saving on the standby current of the ballasts) or to switch a separate channel of standard, non-dimming
luminaires.
Two input terminals can be used to manually override the dimming levels and override the lights on or off.
The flexibility of having two channels and two switch inputs allows the following example scenarios:
1. Dim an outside row of luminaires whilst internal fittings are switched
2. Provide absence detection for two separate channels (see below)
3. Maintained illuminance system with manual up/down controls
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.
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 most applications the EBDSPIR-HB-DD can be used with simple manual adjustment. However, the
EBDSPIR-HB-DD unit has a comprehensive set of features that can be set using the DD-LCDHS-LR
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-HB-DD/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 6.
2. To switch from more than one position simply wire two or more units in parallel using the Live,
Neutral, Switched Live and manual switch wires only. The dimming connection must be wired to
one unit only.
3. Position the sensor according to the detection pattern shown in section 7. 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 above 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. Dimming / external connections
should be made as required according to the applicable wiring diagrams shown in section 6.
9. Use a small screwdriver to set the LUX level adjuster fully anti-clockwise, the time to minimum
(fully clockwise) and the sensitivity to maximum (fully anti-clockwise).
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. For dimming applications, set the light output level by using the LUX adjustment thumbwheel or
the handset. See section 5.5 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).
15. For non-dimming applications the LUX thumbwheel determines the ambient light level at which the
16. Select the time using the adjuster, fully anti-clockwise is the maximum.
Note: the above adjustments can also be made using the DD-LCDHS-LR handset instead of the manual
adjusters. See section 5.
