60W MULTI

PIR BULKHEAD

TLB98-Black/TLW99-White

SECTION ONE

GENERAL INFORMATION

The unit utilises passive infrared technology to detect heat radiation of moving human
bodies.
Upon detection, the lamp will illuminate for a user-determined time period.
An integral daylight sensor ensures night-only operation.

PARTS INCLUDED

- Luminaire c/w PIR Sensor unit.

- Instruction manual. Please keep safe for future reference.

- 22W Compact Fluorescent Lamp

- Accessory Pack.

TOOLS & PARTS NEEDED

- Electric/hand-held drill & bits.

- Terminal or Electricians screwdriver

- Large slotted/philips screwdriver

- Wire cutters

Unit is for outdoor use only. Unit must be mounted on a non-flammable surface as a fixed
luminaire, and is not suitable for portable use.
The unit can get very hot during use. Ensure the unit has cooled before handling.
Ensure adequate ventilation space is allowed between the unit and any object above, in
front or to either side of the unit. Suggested space is 0.5m above, 0.3m to either side &

1.0m in front.
If in any doubt, consult a qualified tradesperson or electrician.

SECTION TWO

SELECTING THE 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 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.).
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.

CONNECTION

Remove the terminal cover (Fig D) to expose terminal block.
Connect the cable to the terminal block as follows (see connection diagram):

NEUTRAL (Blue) N
LIVE (Brown) L

An earth connection is not required. Cut back or simply secure to an alternative
earthing point

Ensure the connections are secure.
Replace terminal cover
Install the lightbulb
Refit cover ensuring it clicks firmly into place

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 1mm

2

gauge is used. A isolating 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.

Remove cover using a small screwdriver (Fig C) by gently easing the cover outwards.
Mark position of the fixing holes. (Fig D)
Drill the holes. Insert the wall plugs into the holes.
Pierce the grommet and pass the cable through the grommet.
Clamp the cable to the rear of the unit before securing the unit to the wall.
Fit grommet into its location hole ensuring a good seal.
Fix the unit to the wall. Take care not to overtighten the screws to prevent damage to the
unit. If using a power screwdriver, use the lowest torque setting.

OPERATION AND TESTING

WALK TEST PROCEDURE

The sensor will rotate from left to right, and tilt forward or backward. Adjust the sensor to
point in the required direction. (note diagram B)

The unit can be set up in daylight or at night. The adjustment knobs are factory set. Lux is
set to the 'moon' setting and Time is set to a minimum (fully anti-clockwise) see diagram E.

Turn the power to the unit on. The lamp will illuminate for approximately 30 seconds. This
indicates the unit is wired correctly.

After approximately 30 seconds the light will turn off.

The unit is now in Test Mode.

TEST MODE - THREE LEDS VISIBLE

The lamp will now illuminate for approximately 5 seconds every time movement is detected.
Walk across the detection area approximately 5 metres from the unit. Each time you are
detected the lamp will illuminate. Now stand still until the lamp extinguishes (this should
take approx. 5 seconds)
Start moving again, when you are detected again the lamp will illuminate.
Repeat the above, walking at various angles and distances to the unit. This will help you to
establish the detection pattern.

If the detection area is too small for your requirements, try angling the sensor head up.
Angling the head downwards will reduce the detection area should a smaller range be
required.

SETTING UP FOR AUTOMATIC OPERATION - THREE SCROLLING LEDS VISIBLE

When walk tests are complete, the unit will be switch into Automatic Mode.
Simply cease movement within the detection area for approximately 60 seconds. The unit
will then switch to Automatic Mode.

The diagram below also shows the required connections for the addition of slave luminaires.
When adding slaves, be sure not to exceed the maximum switchable load (see Technical
Specifications).
