Timeguard SLFM360L - Manual (Page 5)

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.)
including opposite any other light sources such as other security lights.
Reflective surfaces (i.e. 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.
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. We recommend this unit be fitted by a
qualified electrician. Install in accordance with wiring and current
building regulations. Please read the instructions carefully.
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 and allows it to be
conveniently brought into manual override.
Remove the wiring cover from the sensor by depressing the catch
on the side and lifting it clear of the twin locators opposite the catch
(see diagram G).
