Essential Info

The Aleph America APX-201 ceiling mount sensors are dedicated high ceiling PIR intrusion detectors. PIR devices can detect a person moving into or through a detection zone with high reliability. The slightest positive or negative thermal radiation change in contrast to a background triggers the sensor element. There is no interference between neighboring units due to the passive nature of the detection principle. The use of differential or dual-channel sensor technology and advanced digital signal processing reduce false alarms caused by turbulence. Similarly, precision optics accurately define the field of view, allowing consistent and long-range coverage. The sensor is pet immune with the choice switch to selectable sensitivity. The changeable pulse count and sensitivity adjustments allow absolute detection to all interior security applications.

This product is also available with 32 detection zones.
