PYR-3021 Hardwired Ceiling PIR Detector

This extra-wide ceiling unit is designed for easy and comfortable free-height installation and easy wiring, with no PCB adjustment required.  By using fuzzy logic algorithms, detection is improved and false alarms are greatly reduced.

The highly sensitive quad element sensor, encased in a fully sealed chamber, is combined with the state-of-the-art 360˚full vision Fresnel lens for increased detection.

The digital temperature compensation together with the adaptive filter insures equal detection in all situations.

The PYR-3021 has cover and ceiling tamper detection, and jumpers for selecting sensitivity and LED operation.

The easy-to-install and smooth curves design blends inconspicuously into most indoor residential and commercial environments.
