These detectors are streamlined conventional standalone PIR motion detectors that economically deliver reliable performance. A Fresnel lens produces sharplyfocused images throughout the field of view, providing a superior response to intruders. An embedded microcontroller performs First Step Processing (FSP), reducing false alarms and maximizing catch performance. Adjustable mounting height range, a two-piece design, and optional brackets make installation simple and flexible. Temperature compensation helps to maintain and enhance performance in variable climates.

The ISN-AP1-T model detectors offer a cover tamper switch.
