24GHz Small-space presence sensor(ON/OFF version)
MSA215 99 is a 24GHz radar sensor based on Merrytek patented multi-array antenna. Its antenna has high gain and very narrow detection range.Combined with Merrytek’s unique software algorithm,it can accurately detect minor movements brought by human in almost all indoor spaces and best presence detection solution for workspace and toilet cubicle etc small-space scenes.

Product dimension
Initialization
When powered on,sensor indicator will turn off after flashing for 20S and will not detect moving signal during this time. After 20S,you can use our MH10 remote or dip switch to adjust detection area、hold time and daylight sensor etc parameter.
Factory setting
Detection Area:100%, Hold Time: 1Min, Indicator light: Open, Daylight sensor: Disable
Detection Signal
The product detects human moving, minor moving, and presence signals, and realizes the detection of human-existing/no-human in non-sleep state. The following is a description of the moving, minor moving and presence signals:
Wiring layout suggestion:
1. LN terminal stands for AC input, L’N’ stands for AC output,please wiring correctly
2. One sensor’s max loading capacity is 800w resistive loading and 400w inductive loading for one single load.if you want connect more load in one loop,we recommend to add an AC contactor in our output LN terminalto avoid momentary surge overload.
