4. Selecting The Location

The motion detector has various detection zones at different vertical and horizontal angles (see Diagram A). A moving human body needs to cross one of these zones to activate the sensor. The best all-round coverage is achieved when the unit is mounted at an optimum height of 2.5m. If mounted higher, the sensor may need to be angled down slightly, which will reduce forward coverage.

Careful positioning is required for optimum performance (see Diagram A for detection range and direction).

The sensor is more sensitive to movement ACROSS its field of vision than directly TOWARDS it (see Diagram B). Position the unit so the sensor looks ACROSS the likely approach path.

Avoid positioning the sensor near heat sources like extractor fans or tumble dryer exhausts. Reflective surfaces such as pools of water, white-painted walls, or overhanging branches may cause false activation under extreme conditions.

During extreme weather, the motion sensor may exhibit unusual behaviour. This does not indicate a fault; the sensor will resume normal operation once normal weather conditions return.

5. 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.

Remove the jumper plug from the floodlight.
Pass the mains supply and load cables through the holes provided on the PIR, ensuring that a cable gland, grommet or sealing compound is used to maintain the IP rating.

CONNECTION

Connect the mains supply cable to the terminal block on the back plate as follows (see connection diagram E):

EARTH (Green / Yellow) ⚪
NEUTRAL (Blue) N
LIVE (Brown) L

Connect the cable from the slave lighting load backplate as follows (see connection diagram E):

EARTH (Green/Yellow) ⚪
NEUTRAL (Blue) N
SWITCH LIVE (Brown) L1

Ensure that all connections are secure.
Connect the 3-way PIR plug by pushing the plug and socket inside the floodlight together until they lock. DO NOT FORCE. The plug and socket will only fit together one way around (See Jumper Plug diagram).
Secure the PIR to the luminaire using the 4 fixing screws supplied (see diagram G).

6. Commissioning and Operation

Walk Test Procedure

The sensor will rotate from left to right, and tilt up or down. Adjust the sensor to point in the required direction and angle down to limit forward range as required. The unit can be set up in daylight or at night.

Set the time adjustment to the minimum (fully anti-clockwise) and the light threshold to maximum (fully clockwise) (see Diagram C).

Turn the power to the unit on. The lamp will illuminate for approximately 35 seconds. This indicates the unit is wired correctly. The unit is in Automatic Mode when the light turns off.

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

Setting Up For Automatic Operation

When walk tests are completed, the unit can be set up for Automatic Mode.

The TIME setting controls how long the unit remains illuminated following activation and after all motion ceases (See Diagram C, the time adjustment knob is indicated by the "Clock" ⏰ symbol).

The minimum time (fully anti-clockwise) is approx. 3 seconds, whilst the maximum time (fully clockwise) is approximately 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 (See Diagram C). The DUSK adjustment knob is indicated by the "Moon" ? and "Sun" ☀️ symbols).

Set the light threshold to maximum (fully clockwise/Sun end), then turn the control anticlockwise about three quarters of the way round to the Moon end. This will give operation after DUSK approximately.

For a more accurate setting of the DUSK control, turn it fully anti-clockwise (Moon end) and leave for at least 20 seconds for the unit to settle.

When the ambient light level reaches that required for DUSK, adjust the DUSK control a small amount clockwise, pausing to try to get the unit to detect and turn the lights ON by moving a hand slowly backwards and forwards across the front of the detector lens for around 5 seconds.

Continue to turn the control small amounts in a clockwise direction, stopping after each adjustment to try to get the unit to detect as above. Eventually detection will occur and the DUSK level is now set as required.

7. 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 D).
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 area respectively.
Mask the sensor to suit your installation.

8. Manual Override Mode

The light can be switched on for longer time periods by use of the Manual Override Mode. This can be activated by using the internal wall switch or circuit breaker.
Switch the internal wall switch once (OFF/ON) within 1.5 seconds.
The unit will now illuminate continuously for 6 hours, or until switched back into Auto Mode.
To return to Auto Mode, switch the internal wall switch OFF and then back ON again within 1.5 seconds.
The unit will return to its Auto Mode and will operate as set up after the walk test procedure.

9. Detector Head Adjustment

The detector head can be panned 90° to the right and 90° to the left. It can also be tilted down up to 60°.

Diagram showing 90° left/right panning and up to 60° tilt down.

10. Accessing Terminals After Installation

This may be necessary to add further lighting, for instance. The following procedure for removing the unit from its backplate should be followed: Insert the wire through the hole indicated in Diagram F. The terminals are now accessible. If adding lighting, ensure the unit's rating is not exceeded.

11. Troubleshooting

PROBLEM	SOLUTION
Possible stays ON all the time night and day.	Check wiring connections. Wires to L and L1 terminals may be transposed.
Lamp stays ON all the time at night, or PIR keeps activation at random for no apparent reason.	The unit may be suffering from false activation. Cover the sensor lens completely with black PVC tape. This will prevent the sensor from "seeing" anything. If the unit now switches off after the set time duration and does not re-activate, this indicates that the problem was caused by false activation. The problem may be solved by slightly adjusting the direction/angle of the sensor head (see previous section). If, however, the unit continues to remain ON or operate randomly, the unit is faulty and should be replaced.
PIR sensor will not operate at all.	You may not be allowing the unit time to complete its warm-up period. Stand well out of the detection range and wait (the warm-up period should never exceed 5 minutes). Occasionally, winds may activate the sensor. Sometimes passages between buildings etc. can cause a "wind tunnel" effect. Ensure the unit is not positioned so as to allow detection of cars/people using public thoroughfares adjacent to your property. Ensure that the unit is mounted securely; even the slightest movement can result in a false detection. Check that the power is switched ON at the circuit breaker/internal wall switch. Turn OFF the power to the unit and check the wiring connections as per the diagram (see Diagram E). Ensure no connections are loose. Check the bulb. If the bulb has failed, replace (do not hold bulb directly with fingers, use a tissue or clean dry cloth). Ensure that the bulb is seated correctly in the bulbholder.
The PIR sensor will not operate at night.	Refer to section 4 for DUSK control adjustment.
Unit activates during the daytime.	Refer to section 4 for DUSK control adjustment.
PIR coverage is poor/sporadic.	Unit may be poorly located. See previous section "Selecting The Location" and re-locate the unit.
Detection range varies from day to day.	PIR sensors are influenced by climatic conditions. The colder the ambient temperature, the more effective the sensor will be. You may need to make seasonal adjustments to the sensor head position to ensure trouble-free operation all year round.
