Hager OSFM/{ Occupancy Sensor
Hager claims that its new light sensitive occupancy sensor fills a gap in the UK lighting control market for a mid level option. The new OSFM/P is an occupancy sensor that combines switching switchstart luminaires in response to both movement and light levels. It has a detection diameter of 6m when used at 2.4m height. Hager has launched it as an alternative to its higher specification sensor OS2AP.
The occupancy sensor switches the lights on if the ambient light levels are below that set for the photocell and there is any movement. If the light level increases beyond a set lux level or there is no movement detected for a preset time out then the sensor will switch the lights off. It has a switching capacity of 6 amps and is suitable for all fluorescent loads.
Additional functionality includes an adjustable photocell to lux levels between 5 and 1000 lux and an adjustable time out period for the occupancy sensor to between 10 seconds and 45 minutes. It also has a walk test mode as an aid during commissioning. The sensor is programmed using an infrared remote controller and the end user can manually override the sensor using a wall switch or an infrared remote controller.
