difference in controllability: both motion and occupancy sensors can measure ambient light intensity so they will only trigger when certain pre- set lighting thresholds are reached; and both should offer the option to adjust the ON time. More important – the controls should be easy to find and use! With very low-profile flush mount detectors, the controls are hidden in the body of the unit, so look for good spring clips that hold the device securely while still enabling you to remove the unit from an aperture with ease should you need to adjust the settings and replace it securely without damaging the ceiling. Or perhaps, if super-sleek profiling isn’t vital, choose devices that offer external access to the controls without compromising on looks. We’ve proved that surface mount can still look sleek!

preferred where there is no direct ‘line of sight’ for PIR detection, such as through an office partition or washroom partitions etc. Timeguard has a stylish flush mount designed high-frequency microwave detector for LED lighting that fits neatly into a 64 mm ceiling cut out.

Anyplace, any time… We are probably all somewhat familiar with the basic configurations: flush or ceiling mount. Timeguard’s range will also cater for requirements for wall mounting, tamper-proofing etc. There is also a neat take on providing manual override with RF fobs that can be wired behind a standard light switch and concealed in the recessed or surface switch backbox and even work with no mains connection. Naturally, Timeguard offers all the options you’ll need and, as a leading manufacturer of outdoor automatic LED lighting the brand also has

weather-proof outdoor PIR detectors in its range. These include stand-alone models and plug-in modules for the LED Pro range of LED lighting, enabling installers to combine their choice of floodlight power and colour with PIR, RF or photocell actuators.

These RF control fobs can be hand held or fitted in a wall switch backbox where they will work even without a mains connection.
