Arlec 2 Series MAL343 - Movement Activated Compact Sensor Manual

Where to fit your security sensor

To achieve best results for outside use the Arlec Security Sensor should be mounted on a wall, or under eaves of a building, generally used to control an existing light fitting. Ideally the Security Sensor should be mounted 2.4 metres (8ft) above the area to be scanned (Refer Fig.1A).

Always mount with the adjustable controls for LUX and TIME facing downward.
To avoid damage to the unit – do not aim the sensor towards the sun. Sensor can be angled above animal height to avoid nuisance triggering.
To avoid nuisance triggering, the sensor should be directed away from heat sources such as barbecues, air conditioners, other outside lighting, moving cars and flue vents.
Do not aim towards reflective surfaces such as smooth white walls, swimming pools, etc. The Arlec Security Sensor scanning specifications (approximately 12 metres at 180°) 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 Fig.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 Fig.2B).

Installing your security sensor

Must be installed by a licenced electrician or other person authorised by legislation to work on fixed wiring of an electrical installation.

1. Remove junction box base and position against wall or eaves.
2. Using the base as a template, mark and drill the two holes for the masonry plugs or screws. (More holes maybe needed for cable entry and exists. Care should be taken to avoid drilling into concealed electrical wiring.)
3. Run the mains lamp cable through the rubber grommits located in the mounting base.
4. Add silicone around rear of base and cable entry holes.
5. Mount the base using screws provided.
6. Terminate all wires in accordance with Fig.3.
   
   (240 volt mains supply via switch
   To new or existing lighting)
7. Re-assemble sensor and put plastic plugs into assembly screw holes to weatherproof the unit.

Note for electrician:
The security Sensor should be wired to its own switch. Before installation/maintenance, the electrical supply should be isolated. Switching off the wall switch is NOT sufficient isolation to prevent electrical shock.

Understanding the controls

LUX Level adjustment control

Adjusts the light level at which the SecuritySensor operates. Adjust to , the unit will operate day and night. Adjust to , the unit will operate only at night when movement is detected.

Time – time "on" adjustment

Varies the length of time the light will stay ON from about 10 seconds to 7 minutes. Turn anti-clockwise to increase ON-time – ideal setting is about 2 o'clock position (approximately 2 minutes). Whilst there is movement within range of the unit, the light will remain ON. When no further movement is detected, the light will switch OFF after the pre-set time has elapsed.


Be careful of electrical shock. Always remember that the light may not switch ON during daylight or the light maybe in the automatic OFF mode. Never touch live areas unless fuse is removed or circuit breaker is in OFF position at the switchboard main.

Setting the controls

For best results and operation the following steps should be taken:

1. Direct the sensor toward the desired area to be scanned.
2. Turn the light level and time control knobs fully clockwise.
3. Turn the wall switch ON, light will come ON for 30 seconds and then go OFF, provided that there is no movement in the 150° detection area.
4. Have another person move across the centre of the area to be scanned and tilt the sensor until the unit senses the presence of the moving person, causing the light to switch ON.
5. Adjust time control (TIME ON) to required setting.
6. Turn the light level control knob fully anti-clockwise.
7. Your Security Sensor is now ready for use, and will automatically operate when movement is detected at night.
8. The wall switch should remain "ON" for automatic operation.

Automatic mode

Turn your wall switch ON. This will put the sensor into 'automatic' mode and it will then start sensing after dusk. The light will switch ON and automatically switch OFF after the pre-set time elapses and will then operate automatically whenever heat movement is detected.

Manual operation (automatic override)

To override the automatic mode, the sensor must be switched ON in the automatic mode. Now switch wall switch OFF and back ON within one second. Your Security Sensor will now hold your light ON continuously just likes a normal light. This override function can be selected during daytime or night time. To return your sensor to the automatic mode, switch your wall switch OFF for at least 20 seconds, then switch it ON again. To switch your security sensor and lights OFF completely, switch your wall switch OFF.

Maintenance

To avoid dust build-up and ensure proper functioning of the Arlec Security Sensor wipe the lens lightly with a damp cloth every three months. DO not use solvents or abrasive cleaners on any part of your Security Sensor.

Reducing detection area

To reduce the 150° wide angle detection area, stick PVC electrical tape on the left, right or both sides of the sensor lens. This will reduce 150° detection in extremities of area to be scanned. After adding PVC tape some further adjustment of light level control may be necessary.

Specifications

*Power factor correction capacitors must be removed from fluorescent and connected at mains input of sensor.
