Where to fit your
security sensor
To achieve best results the Arlec Security
Sensor should be mounted in a ceiling, or under
eaves of a building, generally used to control an
existing light fitting. The Security Sensor should
be mounted 2.2 - 4 metres above the area to be
scanned (Refer Figure.1).

6m Max
To avoid nuisance triggering, the sensor
should not be installed near heat sources such
as barbecues, air conditioners, other outside
lighting, moving cars and flue vents.
Do not install near reflective surfaces such
as smooth white walls, swimming pools, etc.
The Arlec Security Sensor scanning
specifications (approximately 6 metres at 360°)
may vary slightly depending on the mounting
height and location.
The detection range of the unit may also alter
with temperature change. Before selecting a
place to install the Arlec Security Sensor, you
should note that movement across the scan
area is more effective than movement.

directly toward or away from the sensor
(Refer Figure.2A). If movement is made walking
directly toward or away from the sensor and not
across it, the apparent detection range will be
substantially reduced (Refer Figure.2B).

WarNiNg: Must be installed by a licenced
electrician or other person authorised by
legislation to work on fixed wiring of an electrical
installation.
1. Cut a circular hole into the ceiling, to
accommodate the sensor body (care should
be taken to avoid cutting into concealed
electrical wiring).
Note for electriciaN:

For best results and operation the following
steps should be taken:
1. Mount the sensor above the desired area
to be scanned.
2. Turn the light level control fully clockwise
and time control fully anti-clockwise.
3. Turn the wall switch ON, light will come ON
for 10 seconds and then go OFF, provided that
there is no movement in the detection area.
