To continue the same train of thought as we were having while introducing the Time Lag Switches(which are a good solution for the saving of the energy consumption) and the general intro for the PIR motion detectors, today we want to talk about a specific model – the SLFM360 from Timeguard – principles of functioning, where to locate it, and other features.
360º Flush Mount Ceiling PIR Light Controller – Features
- The SLFM360 utilises passive infrared technology to detect heat radiation of moving human bodies.
- Upon detection, the attached lighting load will illuminate for a user-determined time period.
- An integral daylight sensor ensures all day or night-only operation.
- Light Pollution and Considerate Lighting: Please be aware of the annoyance over-lighting an area can cause to your immediate neighbours.
- Light pollution caused by incorrectly installing a unit or over-lighting an area can be limited by carefully considering the location and position of your unit before installation.
- The light spread on all halogen floodlights can be reduced by angling the floodlight downwards on the mounting bracket.
- This will also concentrate the light on your property and limit the potential inconvenience of the light shining into your neighbours windows etc.
- Please see Selecting a Location for information on choosing the optimum location for any security light controlled by this unit.
- This product is suitable for indoor use only.
- Connected load must not exceed maximum 2000W filament/incandescent or 500W fluorescent/low energy lighting.
- Do not attempt to install if you are suffering from nausea or dizzy spells or on medication with similar side effects.
- If in any doubt, consult a qualified electrician.
- Not suitable for use with discharge lighting.
Parts included in the SLFM360 PIR presence detector
- PIR Sensor unit.

- Accessory Pack. Includes wiring cover, 2 x cable clamps, 4 x clamp screws and 1 x lens mask sticker.
Tools and parts you need for installation
- 3 core flexible cable.
- Electric/hand-held drill & bits.
- 75mm or 3 inch diameter hole cutter.
- Terminal or Electricians screwdriver.
- Small Philips screwdriver.
- Wire cutters.
- Suitable mains interconnect cable.
Selecting a location for the PIR presence detector
- The motion detector has a number of detection zones, at various vertical and horizontal angles as shown.
- A moving human body needs to cross/enter one of these zones to activate the sensor.
- The best all-round coverage is achieved with the unit mounted at the optimum height of 2.5m.
- Careful positioning of the sensor will be required to ensure optimum performance.
- The sensor is more sensitive to movement ACROSS its field of vision than to movement directly TOWARDS. 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 (ie 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.
