PYR-2011A Wireless PIR Detector

The heart of the PYR-2011A is a high quality pyro-electric infrared energy sensor, an advanced digital nano-watt microcontroller, and an A to D signal analyzer.

This full sized wireless spherical sensor blends into any environment, keeping a low profile while providing state-of-the-art optics. An advanced spherical lens made out of patented materials provides white light immunity. The optic pattern includes look-down (creep) zone protection using a mirror and curtain zones with a unique snap-in curtain mask that enables focused detecting, such as across window surfaces or down corridors.

The PYR-2011A’s many features include a fully sealed sensor chamber, easy-to-operate magnetic walk and RF transmission test, dynamic and static transmission modes, selectable sensitivity level, cover and wall tamper detection and automatic low battery detection.
