Installation & Operating
Instructions
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.
- Accessory Pack.
- 2 x 230V 75W PAR30 ES Reflector lamps
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.
TEST MODE - 3 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 - 3 SCROLLING LED’S 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, ensure the
lamp is not illuminated. The unit will then switch to Automatic Mode, this is indicated by
the illumination of three scrolling LEDS in the top transparent area of the sensor head.
These LED's will scroll from left to right during daylight and darkness.
The TIME setting controls how long the unit remains illuminated following activation and
after all motion ceases.
(See diagram G. the time adjustment knob is indicated by the "Clock" symbol).
The minimum time (fully anti-clockwise) is approx. 5 seconds, whilst the maximum time
(fully clockwise) is approx. 5 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:
(See diagram G. the Dusk adjustment knob is indicated by the "Moon" and "Sun symbols).
Set the DUSK control knob fully anti clockwise. Wait until darkness falls.
When the ambient light level reaches the level of darkness at which you wish the lamp to
become operative (i.e.: at dusk) SLOWLY rotate the control in a clockwise direction until a
point is reached where the lamp illuminates. 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 light) adjust the control slightly anti-clockwise. If the unit
starts to operate too late (i.e.: when it is very dark). Adjust the control slightly clockwise.
Continue to adjust until the unit operates as desired.
The LED's will scroll from left to right, day and night; indicating the unit is in Automatic
Mode. The LED's will extinguish when the PIR activates the light for as long as the lamp is
illuminated.
MASKING THE SENSOR LENS
To restrict the sensor coverage, preventing detection in unwanted areas, mask the sensor
lens using the masks provided in the accessory pack (see diagram H). 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 respectively.
MANUAL OVERRIDE MODE - SINGLE LED ILLUMINATED
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 internal wall switch/circuit breaker twice (off/on, off/on) within 2 seconds. The
unit will now illuminate continuously or until it is switched back into Auto Mode.
SECTION THREE
INSTALLATION
After choosing a suitable location (see previous section) install the unit as follows:
Romove the wiring box cover by unscrewing the retaining screw (fig F) and with a
screwdriver gently push down and ease out. The unit is suitable for connection to a 230 V ac
50Hz electricity supply. It is suggested that 3-core round flexible cable of 1mm2 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 off when not required or for maintenance purposes.
Mark position of the fixing holes. (Fig C)
Drill the holes. Insert the wall plugs into the holes.
PASS THE CABLE THROUGH THE WALL BRACKET BEFORE SECURING WALL BRACKET
TO THE WALL.
Pierce the grommet and pass the cable through the wall bracket.
Allow approximately 70mm of cable to pass through the grommet. (A template for this wire
length is provided on the rear cover of this manual).
Fit grommet into its location hole ensuring a good seal.
Fix the mounting plate to the wall. Take care not to overtighten the screws to prevent
damage to the mounting plate. If using a power screwdriver, use the lowest torque setting.
*** 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.
CONNECTION
This unit is supplied with a hanging attachment (tether) to aid installation.
If it is not required, simply remove from the unit and discard.
Place the round end of the tether into the keyhole shape location hole on the wall bracket.
Ensure the tether is securely fixed into the slot before releasing the weight of the unit.
The unit can now be suspended below the wall bracket. (Fig D)
Connect the cable to the terminal block as follows (see connection diagram):
NEUTRAL (Blue) N
LIVE (Brown) L
An EARTH connection will only be required if metal encased slave luminaires which are not
double insulated are to be in use.
Ensure the connections are secure.
Place terminal block onto its securing pillar on the wall bracket (Fig E)
Remove and discard the tether.
Fit floodlight to wall bracket and secure by fixing screw (Fig F)
Install the PAR 30 lamps. Ensure the fixed rubber gasket is securely fitted to cover the metal
rim of the lamp and lampholder.
