Bosch Quad Passive Infrared PIR Sensor ...
The DS940Q is a wall-mount, Quad Passive Infrared Intrusion Detector. This detector employs two individual sensors, which operate like two PIRs in one. Each sensor is processed separately and both must activate to cause an alarm.
The DS940Q combines two PIRs that each use First Step Processing (FSP). First step processing (FSP) responds to human intruders while ignoring other sources of motion, minimizing false alarms.
You do not need to select the sensitivity levels for the application because FSP adjusts the detector's sensitivity based on signal amplitude, polarity, slope, and timing. Each sensor is processed individually, and both sensors must agree there is an alarm before the alarm relay is activated.
