High-mounting PIR motion sensor (KNX version)
MSA237K 99 IR is a high-mounting PIR motion sensor with daylight detection function. Combined with the unique software algorithm of Merrytek, it can accurately detect human movements in almost all high-mounting scenario to trigger smart scene application in warehouse,lobby,workshop etc by KNX communication.

Initialization
When powered on,sensor indicator will turn off after flashing for 10S and will enter a 20S detection cycle,if there’s presence detected,then sensor will enter hold time calculating,if absence detected,then sensor relay will disconnect.During initialization,sensor will not detect moving signal and you can use our MH10 remote to adjust detection area、hold time and daylight sensor etc parameter.
Factory setting
Detection Area: 100%, Hold Time: 30S, Indicator Light: open
