2. Description and Operation
The EBDSPIR-PRM PIR (passive infrared) detector provides automatic control of lighting loads with
optional manual control. 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
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.

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, Switched Live and manual switch wires only.
3. The detector should be sited so that the occupants of the room fall inside the detection pattern
shown in section 5, at a recommended ceiling height of 2.8m. Note that the lower the sensor is
installed the smaller the detection range will be, subject to the parameters shown on the diagram.
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 overleaf.
9. 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.
10. 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).
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
minutes).
13. Check that the load switches on when movement is detected.
14. The LUX thumbwheel determines the ambient light level at which the lights turn on.
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;
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 4.3
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 handset instead of the manual
adjusters or external switches. See section 4.

4. Programming
All the following functions can be programmed using the remote control DD-LCDHS handset:
1. Detector Parameters (factory default in brackets):
1.1 Time adjustment 10 seconds to 99 minutes time delay (select 0 for 10 second
delay – use for commissioning only).
1.2 Sensitivity On (9) Sensitivity level when the detector is already operational
adjustable between 1 (min.) and 9 (max.)
1.3 Sensitivity Off (9) Sensitivity level for switching the detector on – adjustable
between 1 (min.) and 9 (max.).
1.4 Power Up On (Y) Select No for a 30 second delay on start up. If Yes is selected,
there will be no delay on start up and the detector will always
power up detecting.
1.5 Walk Test (N) An LED behind the detector lens will flash to show movement
has been detected (use for commissioning).
1.6 Disable Detector (N) Disables detection. In this mode the detector acts as a
photocell only. The lux preset determines the light level at
which the output is turned on. The sensitivity preset
determines the light level at which the output turns off. The
time preset prevents nuisance tripping and in this mode is
adjustable between 0-13 minutes.
1.7 Factory Default Restores factory default settings.
2. Switching functions (factory default in brackets):
2.1 Presence detection Auto switch on with detection, auto off after movement ceases
(default) and time delay ends.
2.2 Absence detection Manual switch on, auto off after movement ceases and time
delay ends.
2.3 Switch level on (9) Lux level setting to prevent the luminaires being switched on if
and 9). The luminaires will always be switched on at level 9.
2.4 Switch level off (9) Lux level setting to switch the luminaires off during occupancy

5. Detection Diagram
Area of lower sensitivity Area of high sensitivity
LOAD DOES NOT COME ON
Check to see if the live supply to the circuit is good.
Strap across the L and LIVE OUT terminal to turn
the load on.
If the supply and wiring are good, check the LUX
level setting. Increase the LUX level setting to allow
the controller to turn on at higher ambient natural
light level.
If the detection range is smaller than expected,
check the diagram above. Rotating the sensor
slightly may improve the range.
6. Fault Finding
LIGHTS DO NOT GO OFF
Ensure that the area is left unoccupied for longer
than the selected timer setting.
Make sure that the sensor is not adjacent to circulating air, heaters or lamps.
