Dual-technology PIR Black

 This detector registers infrared changes and movements in the detection field. If a person is in the detection field, the PIR activates the MW detector. Only after receiving a confirmed alarm signal from the MW detector does the Ajax MotionProtect Plus send an alarm signal to the Ajax hub. The combination of PIR and MW detection gives this detector a high level of reliability and verification in difficult conditions. For example, in blinding sunlight, in the event of sudden temperature fluctuations caused by heating or air conditioning, etc. PIR sensors feature a number of curtain fields. Thanks to this, the sensitivity of the detector remains the same whether the distance is small or large, and there is always effective detection, even in the presence of obstacles.
