Timeguard STFM360 Suretime Flush Mount 360° PIR

The Timeguard STFM360 Suretime Flush Mount 360° PIR is a compact ceiling motion sensor designed to control indoor lighting automatically. It detects movement and switches connected lights on, helping make everyday spaces more convenient while reducing the chance of lights being left on unnecessarily.

This flush-mounted PIR sensor is ideal for areas where hands-free lighting is useful, including hallways, landings, toilets, cupboards, storerooms, utility rooms, corridors, offices and communal indoor areas. Unlike a surface-mounted PIR, the STFM360 is designed to sit recessed into the ceiling for a cleaner, more discreet finish.

With 360° detection, the sensor provides wide coverage from a ceiling position. At a 3m mounting height, it offers a detection range of up to 6m, making it suitable for many standard domestic and light commercial rooms. The included 60mm ceiling cut-out requirement makes it suitable for neat flush installation in compatible ceiling types.

The adjustable ON time lets users choose how long the lights remain on after movement is detected, from 3 seconds to 18 minutes. The adjustable daylight setting, from 10 to 1000 lux, allows the sensor to be set so lights only activate when the room is dark enough. This helps avoid unnecessary switching during daylight hours.

The Timeguard STFM360 is suitable for LED lighting loads up to 200W and incandescent or halogen loads up to 1000W. It also includes a manual override pulse facility for extended light-on times, and up to 5 STFM360 PIR sensors can be wired in parallel, provided the total lighting load does not exceed the rating of a single unit.

Finished in white with a polycarbonate body, the STFM360 is a discreet PIR light controller for homes, rental properties, offices and shared indoor spaces. It is IP44 rated for restricted internal applications, Class 2 protected and supplied with a 2-year manufacturer guarantee.
