IntroductIon
The Arlec MAL535 Movement Activated Sensor Light is a compact sensor light unit. It controls two
PAR38, 150W floodlight bulbs for wide area illumination. The MAL535 can be used to provide lighting
for security and general purposes in a variety of locations around the home or workplace.

IMPORTANT: Loosen all lock nuts and screws
on sensor and lamp holders before making
any adjustments.
NOTE: Always face control knobs on sensor
downwards to ensure correct operation.
LOcATION Of uNIT.
IMPORTANT: When mounting unit, ensure
that supply cable is held securely away from
the globes using cable clips ( not supplied).
To achieve best results for exterior use, your
Movement Activated Floodlight should be
securely mounted to a wall or eaves in close
proximity (max 300mm) to an existing bayonet
style light fitting.
For ideal operation the sensor head should
be located approx 2.5m above the area where
movement is to be sensed. This will provide the
best scanning sensitivity and detection area.
• Although this product is weatherproof it is
preferable to mount your Floodlight in a
sheltered or semi-sheltered location.
• To avoid damage to unit - do not aim the
sensor towards the sun.
• To avoid nuisance triggering, the sensor
should be directed away from heat sources
such as BBQ's, air conditioners, other outside
lighting, flue vents and moving cars.
• Do not aim towards reflective surfaces
such as smooth white walls or swimming
pools etc.
• The scanning specifications (10m at 180°
scan) may vary slightly depending on the
mounting height and location. (Refer Fig. 2)
The detection range of the unit may also alter
with temperature change.
• Before selecting a place to install the
Floodlight, you should note that movement
across the scan area is more effective than
movement directly toward or away from
the sensor. (Refer Fig. 3A). If movement is
made walking directly towards or away from
the sensor and not across, the apparent
detection range will be substantially reduced
(Refer Fig. 3B).
• Avoid locating your Floodlight in close
proximity to fluorescent light fittings or
ceiling fans on the same electrical circuit.
RFI interference may cause the Floodlight to
switch on inadvertently.

The light must be wired to its own light switch.
Do not interconnect with other lights on the
same switch.
