Arlec MAL535 Installation Instructions page 3

InStaLLatIon
Select a position within 300mm or so of an
existing light fitting with a bayonet socket.
The MAL535 plugs into that light fitting, effectively
replacing that light with a sensor light.
waLL MountIng
Place the junction box over the position for
mounting and mark the screw holes. Use the
two mounting lugs on the outside of the junction
box, and ensure the "TOP" marking points
upwards. Drill suitable holes and fit screws to
fix junction box to the mounting surface, again
ensuring the "TOP" marking is pointing upwards.
eave MountIng
Use a similar procedure to wall mounting, but
the "TOP" marking should point towards the
outside of the eave. We suggest 2 x spring
toggle screws (not supplied) be used to mount
your Floodlight under eaves. Take care not
to damage or pierce concealed wiring with
mounting screws, particularly when mounting
under eaves.

IMPORTANT: Be careful of electric shock
hazards. Always remember that the lights may
not switch ON during the daylight or the lights
may begin automatic OFF mode. Never touch
live areas unless the power plug is removed
or circuit breaker at main switchboard is in the
OFF position.
To connect to power, simply plug the cord
into a suitable outlet. Ensure that all
connections are protected from weather.
IMPORTANT: After mounting unit, ensure that
the cord is held securely away from contact
with the globes. Use cable clips (not supplied)
if necessary.

SettIng up
Do not overtighten or use excessive force
when adjusting sensor head or lamp holders.
Loosen lock nuts or elbow/joint screws to make
adjustment.
A. Adjust the direction of the sensor arm and
lampholders to suit the desired detection
area. Loosen lock nuts and elbow screws on
lampholder before making any adjustments.
Do not use excessive force when making
adjustments to lampholders (See Fig. 7).
B. Angle sensor slightly downward towards
the detection area. The sensor joint should
be rotated to adjust the sensor to face the
required detection area. If necessary, loosen
sensor arm joint clamp screw.
C. Angle lampholders from mounting surface
and direct them approximately downwards
away from sensor head.
D. Fit PAR38 globes and weatherproofing
rubber seals- do not overtighten.
E. Ensure that globes are positioned 40mm
or more from the sensor head or mounting
surface as shown in (Fig. 8). The globes
become very hot and must not be touching
or too close to sensor head.
F. After fitting globes, tighten elbow screws and
lock nuts- do not overtighten.

understanding the controls
Time - Time "ON" adjustment
The time "ON" control adjusts the time that
the lights will remain on after the unit has
sensed movement. To increase time, turn the
knob clockwise. To decrease, turn knob anti-
clockwise.
Lux - Light level adjustment
The "Lux" control adjusts at what level of light
the unit starts sensing at dusk. This control can
be also used for testing the unit during daylight
hours. To test unit, or operate during the day,
turn control knob all the way anti-clockwise.
Once unit has been tested the "Lux" control
should be set to approx half way, and adjusted
later if required.
Sens - Sensitivity adjustment
The Sensitivity control adjusts the level of
sensitivity of the infrared Sensor. This controls
the amount of movement that is required
to switch the lights on. With the knob set to
minimum (anticlockwise), the unit will only
detect large amounts of movement. It is
recommended that in most situations the unit
be operated with the "Sens" control set to half.
Setting the controls
1. Turn the "LUX" or light control to minimum,
turn the wall switch ON and wait for half a
minute for the control circuit to stabilise. At
this stage ensure that the time control is set to
"minimum". The Floodlights will now switch on
and remain on for about 10 seconds.
2. Turn the "SENS" control to minimum.
3. Direct the sensor toward the desired area
to be scanned by adjusting the elbow joint
and ball joint on the sensor arm. Loosen lock
nuts and screws before attempting to adjust
sensor arms.
