Timeguard ECO36PIR User Manual

1. 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.
The bulb supplied with the ECO36PIR is a class B (high efficiency) unit of 36W power
consumption giving a similar but more diffuse light output to the lower efficiency 150W
halogen units previously in use.
PARTS INCLUDED
- PIR flood light unit.
- Instruction manual. Please keep safe for future reference.
- Spiral 36W lamp.
TOOLS & PARTS NEEDED
- Electric/hand-held drill & bits.
- Terminal or Electricians screwdriver
- Medium slotted/philips screwdriver
- Wire cutters
This product is suitable for wall mounting. (Unsuitable for soffit mounting).
2. SELECTING THE LOCATION
The motion detector has a number of detection areas, at various vertical and horizontal
angles as shown (see Figs. 1 & 2).
A moving human body needs to move between zones within one of these areas to activate
the sensor. The best all-round coverage is achieved with the unit mounted at the optimum
height of 2.5m. Forward looking range will be reduced by approx. 0.4m if the mounting
height is 4m with sensor angled slightly downward.
Careful positioning of the sensor will be required to ensure optimum performance.
See Fig. 1 detailing detection range (the ranges shown depend on the face of the
PIR lens being vertical to the ground).
The sensor is more sensitive to movement ACROSS its field of vision than to movement
directly TOWARDS (see Fig. 2). Therefore position the unit so that the sensor looks ACROSS
or to ONE SIDE of the likely approach path.
Avoid positioning the sensor where there are any sources of heat in the detection area
(extractor fans, central heating flues, 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.
The unit should be mounted with the following minimum clearances:-
Above and to each side 0.3m. In front 1.0m
