Int roduction

The PDSM1500.1 utilises passive infra red technology to
detect heat radiation of moving human bodies.Upon
detection, the

lighting load will illuminate for
a use r-determined time period. An integral daylight
sensor ensu res all day or night-only operation.

Important Information: Light Pollution and
Considerate Lighting

Please be aware of the annoyance over-lighting an area
can cause to your immediate neighbours. Light
pollution caused by incor rectly installing a unit or
over-lighting an area can be limited by carefully
considering the location and position of your unit
before installation. The light spr ead on all halogen
oodlights can be reduced by angling the oodlight
downwa rds on the mounting bracket. This will also
concentrate the light on your property and limit the
potential inconvenience of the light shining into your
neighbours windows etc.
Please see Selecting a Location for information on
choosing the optimum location for any security light
controlled by this unit.

5. Selecting a Location

• The motion detector has number of detection zones, at various vertical
and horizontal angles as shown (see diagram A).

• A moving human body needs to cross/enter one of these zones to activate
the sensor. The best all-round coverage is achieved with the unit mounted
at the optimum height of 3 metres.

• Careful positioning of the sensor will be required to ensure optimum
performance (see diagram A detailing detection range and direction).

• The sensor is more sensitive to movement ACROSS its field of vision
than to movement directly TOWARDS (see diagram B). Therefore position
the unit so that the sensor looks ACROSS the likely approach path.

• Avoid positioning the sensor where there are any sources of heat in the
detection area (extractor fans, tumble dryer exhausts etc.) including opposite
any other light sources such as other security lights.

• Reflective surfaces (i.e. pools of water or white painted walls) and overhanging
branches may cause false activation under extreme conditions.

• During extreme weather conditions the motion sensor may exhibit unusual
behaviour. This does not indicate a fault with the sensor. Once normal weather
conditions return, the sensor will resume normal operation.

6. Installation & Connection

• An isolating switch should be installed to the switch the power ON & OFF.
This allows the sensor to be easily switched OFF when not required for
maintenance purposes.

• Remove the top cover of the sensor by twisting the top cover anti-clockwise
until the arrows (shown on diagram E) are aligned. The top cover can now be
removed from the sensor body.

• Mark the position of the fitting holes (see diagram D). Drill the holes.
Insert the rawl plugs into the holes.

• Pass the supply cable through the cable entry point on the foam gasket
and then the mounting plate, ensuring the grommet is used to maintain
the IP rating of the PIR sensor.

• Terminate the cable into the terminal block ensuring correct polarity is observed
and that all bare conductors are sleeved (see below details on connection).

There are 2 possible connection scenarios

5 6

Standard connection – 230v Mains Installation (see diagram G)

The factory fitted ‘bridge’ wire must not be removed.

Connect the 4 core mains supply cable to the block on the unit as follows:-

NEUTRAL (Blue) N

EARTH (Green/Yellow)

LIVE (Brown) L

Connect the fourth core cable from the lighting load to the L1 terminal block
on the unit as follows (see connection diagram G).

SWITCHED LIVE L1

6

Switching DC loads or loads which use a different phase or voltage
supply from the AC mains – Voltage free Installation (see diagram H)

Remove the factory fitted ‘bridge’ wire.

Connect the 3 core 230V 50Hz mains supply cable to the terminal block
on the unit as follows:-

NEUTRAL (Blue) N

EARTH (Green/Yellow)

LIVE (Brown) L

Connect the load in series with the load supply between L1 and L2 terminals.

Please note that the function of L1 and L2 can be views as a simple switch
controlled by the PIR sensor electronics.

• When wiring is complete, it is recommended that the ceiling mounting plate
is fitted to the sensor body and fixed to the ceiling as follows:
(See diagram ‘I’ for ceiling mounting assembly method.)

• Insert fixing screws through the sensor assembly into the wall plugs and secure.
Do not over-tighten, if using a power screwdriver ensure it is set to a low torque
setting so as not to damage the unit. Set the unit up as follows, before refitting
the decorative cover.

7. Setting Up

Walk Test Procedure

• Set the two adjustment controls on the underside of the unit (see diagram C)
to the following positions:
TIME – Fully anti-clockwise
DUSK – Fully clockwise.

• The unit will now operate during daytime as well as at night, illuminating the
lamp for approx. 5 seconds each time. This allows testing to be carried out to
establish whether the sensor is covering the required area.

• The lamp will immediately illuminate as the unit goes through its ‘warm-up’
period. After approximately 1 minute the lamp will extinguish. Try to remain
outside the detection area during the warm-up period.

• Walk around the sensor to establish the detection area. The sensor will detect
within an approximately 9m diameter circle from the centre of the sensor
location with a 3m ceiling. As you cross a detection ‘zone’ the lamp
will illuminate.

7 8

• Now stand still until the lamp extinguishes (this should take approx. 5 seconds).
Start moving again after 2 seconds. As you cross each ‘zone’ the lamp
will illuminate.

• Repeat the above, walking at various distances and angles to the unit.
This will help you to confirm the detection pattern.

Setting Up for Automatic Operation

• When walk tests are complete, the unit can be adjusted for automatic
operation:
The TIME setting controls how long the unit remains illuminated
following activation and after all motion ceases. The Time control knob
at fully anti-clockwise is Test Mode, slightly adjust to above the T is
minimum time approx.
1 minute, whilst the maximum time (fully clockwise) is approx. 30 minutes.
Set the control to the desired setting between these limits.

8

• The DUSK control determines the level of darkness required for the unit
to start operating. The setting is best achieved by the procedure below:
Set the DUSK control knob fully anti-clockwise. The unit will now start
operating at dusk.

• If you require the light to activate earlier, wait until the ambient light level
reaches the level of darkness at which you wish the lamp to become operative,
SLOWLY (a small step at a time) rotate the control in a clockwise direction until
a point is reached where the lamp illuminates in response to a hand moving
below the unit. Leave the control set at this point. At this position, the unit
should become operative at approximately the same level of darkness
each evening.

• Observe the operation of the unit. If the unit is starting to operate too early
(i.e. when it is quite bright), adjust the control slightly anti-clockwise. If the unit
starts to operate too late (i.e. dusk), adjust the control slightly clockwise.

• Continue to adjust until the unit operates as desired.

8. Masking the Sensor Lens

• To reduce the sensor coverage, preventing detection in unwanted areas,
mask the sensor lens using the lens mask sticker supplied (see diagram C).

• For your information, the centre section of the lens covers short range detection,
and the outer edge of the lens covers long range.

• Mask the sensor to suit your installation.

9. Troubleshooting Guide

Problem

• Lamp stays

ON all the
time at night.

• PIR keeps

activating for
no reason
(at random).

• PIR sensor will

not operate at all.

• The PIR sensor

will not operate
at night.

• Unit activates

during the daytime

Solution

Cover PIR lens with a thick cloth. If the light turns
out, check detection area for heat or reflective source.

If the light stays on, check the wiring.

See section 6.Installation & Connection

Turn off at the isolation switch. Turn back on again
after 30 seconds. Leave for approximately
15 minutes.

If the light activates, check area for false activation
from heat, wind or reflective source.

Check that the power is switched ON at the power
supply or isolation switch.

Turn OFF the power to the unit and check the
wiring connections.

Check the lamp. If the lamp has failed, replace.
Ensure that the lamp is seated correctly in the
lampholder. Please note that the unit will not detect
through glass. (e.g. in a glazed porch).

The level of ambient light in the area may be too
bright to allow operation at the current DUSK setting.
During the hours of darkness, adjust the DUSK
control slowly clockwise until the lamp illuminates.
Refer to previous section for more details.

Adjust the DUSK Control setting anti-clockwise to
lower the level of ambient light required
for activation.
