This ceiling mounted PIR Motion Sensor has a 360° coverage angle and a 6 metre detection radius when at a height of 2.2 to 4 metres. It's capable of detecting infrared emissions from any heat source without emitting any radiation._x000D_ The detector activates its output circuit when a heat source moves in front of the switch and deactivates when the heat is no longer detected and some time has passed. _x000D_ _x000D_ Detection Angle: 360°_x000D_ Detection Distance: 3 to 6 metres. _x000D_ Minimum ON time: 10 seconds ±3 seconds._x000D_ Maximum ON time: 7 minutes ±2 minutes._x000D_ Installation Height: 2.2 to 4 metres._x000D_ Detection Speed: 0.6-1.5 m/s._x000D_ Charges: 300W LED and 1200W Incandescent.
