Timeguard SLW2400 User Manual

2400W PIR L IGHT

C O N T R O L L E R

Cat No. SLW2400

Introduction

The SLW2400 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 enables 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.

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 2.5m.

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

This unit will not detect through glass (e.g. in a glazed
porch).

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
detector 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.

Light pollution

To reduce the risk of light pollution, consider the
following when installing the any lights controlled

by this unit.
Position the light to ensure that the light emitted does

not encroach onto neighbouring properties.
Angle the floodlight downward to focus the

illumination onto the ground, not into the sky.
Consider using a lower wattage bulb (200W/300W for

a 500W floodlight) to save energy and reduce high light
output if not required.

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.

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 internal
switch should be installed to switch the power to the
unit ON & OFF. This allows the sensor to be easily
switched off when not required or for maintenance
purposes.

This product is designed to be mounted on walls or
under eaves, see diagram E. The sensor can be rotated
through 180 degrees to direct detection where required,
consider your location carefully before installation.

Remove the unit from its packaging.
Unscrew the wiring box fixing screw shown on

diagram F. This screw is captive, do not fully remove.
Detach the wiring box from the Sensor body.
Using the wall plate as a template, mark the position of

the fitting holes.
Drill the holes. Insert the wall plugs into the holes.
PIERCE & PASS THE CABLE(S) THROUGH THE

GROMMET(S) BEFORE PROCEEDING.
It is recommended that the grommet is pierced with a

screwdriver to ensure a better seal.
Attach the mounting plate to the wall using screws

provided. Do not overtighten the mounting
screws as this could damage the unit. If using a power

screwdriver, use the lowest torque setting.
This unit features an installation aid. Simply hang the

Sensor onto the wall plate by use of the clip

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 internal wall switch or
circuit breaker.

Switch the isolation switch (off/on, off/on) within 2
seconds. The unit will now illuminate continuously
until dawn or until it is switched back into Auto Mode.

To switch the unit back into Auto Mode, switch the
isolation switch off/on once within 1 second. The unit
will return to Auto Mode.

Operation and testing

Walk Test Procedure

The detector will adjust vertically through 180 degre e s
Adjust the detector to point at the desired elevation.
Angling down will limit forward looking range.
Set the two adjustment controls on the underside of the
unit (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 detection occurs. This allows testing to be carried
out to establish the best position for the sensor. 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
a r ea during the warm-up period.
Walk across the detection area approx 5 metres from the
unit. 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.

7

Repeat the above, walking at various distances and
angles to the unit. This will help you to establish the
detection pattern.
If the detection area is too small for your re q u i re m e n t s ,
try angling the detector head up. This will increase the
coverage distance. Angling the head downwards will
reduce the range should a smaller coverage area be
re q u i re d .

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 re m a i n s
illuminated following activation & after all motion
ceases. The minimum time (fully anti-clockwise) is
a p p r ox. 5 seconds, whilst the maximum time (fully
clockwise) is approx. 18 minutes. Set the control to the
d e s i r ed setting between these limits.
The DUSK control determines the level of darkness
re q u i red for the unit to start operating. The setting is
best achieved by the pro c e d u r e below:
Set the DUSK control knob fully anti-clockwise. The unit
will now start operating at dusk.
If you re q u i re 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
d i r ection until a point is reached where the lamp
illuminates when a hand is moved across the front of the
d e t e c t o r. Leave the control set at this point.
At this position, the unit should become operative at
a p p r oximately the same level of darkness each evening.
Observe the operation of the unit. If the unit is starting
to operate too early (ie. when it is quite light), adjust the
c o n t r ol 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 desire d .

Masking the Sensor Lens

To restrict the sensor coverage, preventing detection in
unwanted areas, mask the sensor lens using the masks
p r ovided in the accessory pack (see diagram D). For
your information, the top section of the lens covers long
range detection, the bottom covers short range. Similarly
the left and right lens sections cover the left and right
detection areas re s p e c t i v e l y.

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 wiring. See
Section 3.

Turn the unit off at the isolation switch.
Turn back on 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
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 setting anti-clockwise to lower
the level of ambient light required for
activation.
