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.

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

SLFM360_Instruct_art_2.2.qxd 3/5/06 10:05 am Page 4

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.

SLFM360_Instruct_art_2.2.qxd 3/5/06 10:05 am Page 6

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.

SLFM360_Instruct_art_2.2.qxd 3/5/06 10:05 am Page 8

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.
