Introduction
The SLFM360 utilises passive infrared technology to
detect heat radiation of moving human bodies.Upon
detection, the attached lighting load will illuminate for
a user-determined time period. An integral daylight
sensor ensures 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 incorrectly 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 spread on all halogen
floodlights can be reduced by angling the floodlight
downwards 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.

nausea or dizzy spells or on medication with similar
side effects. If in any doubt, consult a qualified
electrician.
Not suitable for use with discharge lighting.
Selecting a location
The motion detector has a 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
SLFM360_Instruct_art_2.2.qxd 3/5/06 10:05 am Page 3

optimum height of 2.5m.
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 (ie 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.
Installation
IMPORTANT
Switch off the electricity at the fuse box by removing the
relevant fuse or switching off
the circuit breaker before proceeding with the installation.
All fittings should be installed by competent person in
accordance with IEE Wiring Regulations (BS7671)
After choosing a suitable location (see previous section)
install the unit as follows:
The unit is suitable for connection to a 230 V ac 50Hz
electricity supply. It is suggested that 3-core round
flexible cable of 1 sq. mm gauge is used. An isolating
switch should be installed to switch the power to the unit
ON & OFF. This allows the sensor to be easily switched

Connection
THERE ARE 2 POSSIBLE CONNECTION SCENARIOS
1. Standard connection (see diagram E).
The factory fitted “bridge” wire must not be removed.
Connect the 3 or 4 core mains supply cable to the
terminal block on the unit as follows:-
NEUTRAL (Blue) N
EARTH (Green/Yellow)
LIVE (Brown) L
Connect the fourth core (lighting live) of the four core
cable (if used) to the L1 terminal block or the second 3
core cable (from the lighting) to L1 (brown), N (blue)
and E (green/yellow).
2. Switching DC loads or loads which use a different
phase or voltage supply from the AC mains (see
diagram F). Remove the factory fitted bridge wire.
Connect the 3 core 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.
off when not required or for maintenance purposes and
allows it to be conveniently brought into manual
override.
Remove the wiring cover from the sensor by
depressing the catch on the side and lifting it clear of
the twin locators opposite the catch (see diagram G).
Mark the position of the 75mm diameter locating hole
centre taking care to avoid ceiling joists and other
obstructions within the 75mm diameter. Drill a pilot
hole to take the centre shaft of the hole cutter. Use the
hole cutter to cut the required hole.

Setting up
Walk Test Procedure
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 - 2
minutes 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 six metre
diameter circle from the centre of the sensor location with a
2.5m ceiling.
As you cross a detection "zone" the lamp will illuminate.
Now stand still until the lamp extinguishes (this should
take approx. 5 seconds).
Start moving again. 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.
Please note that the function of L1 and L2 can be
viewed as a simple unconnected switch controlled by
the PIR sensor electronics.
When wiring is complete, set the two adjustment
controls on the side of the unit (diagram D) to the
following positions:
TIME -Fully anti-clockwise.
DUSK - Fully clockwise.
Push back the locating springs (diagram E) and feed
the unit into the ceiling void via the 75mm hole. The
locating springs will now fold back and hold the
SLFM360 in place.

Setting Up for Automatic Operation
When walk tests are complete, the unit can be adjusted
for automatic operation :
To access the controls use a knife or thin flat blade
screwdriver to gently lever (see diagram E) the unit
clear of the ceiling. Hold in position against the spring
pressure while making adjustments.
The TIME setting controls how long the unit remains
illuminated following activation & after all motion
ceases. The minimum time (fully anti-clockwise) is
approx. 5 seconds, whilst the maximum time (fully
clockwise) is approx. 18 minutes. Set the control to the
desired setting between these limits.
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
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.

to operate too early (ie. when it is quite light), adjust
the control slightly anti-clockwise. If the unit starts to
operate too late (ie. dusk), adjust the control slightly
clockwise.
Continue to adjust until the unit operates as desired.
Once the unit is set up as desired, ease the unit back
into position under spring pressure.
Manual Override Mode
The light can be switched on for longer time periods by
use of the Manual Override Mode. This can be
activated at night by using the isolation switch.
Switch the isolation switch twice (off/on, off/on)
within 2 seconds. The unit will now illuminate
continuously until dawn or until it is switched back
into Detection Mode.
To return to Detection Mode switch the isolation switch
off and then back on again within 1 second.

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 wiring.
See Section 3.
Turn off at the isolation switch. Turn
back on again after 30 seconds. Leave
for approximately 18 minutes.
If 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.
