SATEL SLIM-R-DUAL-AC Dual Technology PIR & Microwave Motion Detector

With a 15 m x 24 m detection range at 90° and dual PIR + microwave technology operating at 24.125 GHz, the SATEL SLIM-R-DUAL-AC delivers Grade 2 security performance in a sleek, low-profile housing. This wired motion detector combines passive infrared and microwave sensing to reduce false alarms while maintaining reliable intruder detection.

Overview

The SLIM-R-DUAL-AC is a professional-grade dual technology motion detector designed for indoor security installations. It uses independent PIR and microwave channels that must both trigger to generate an alarm, significantly reducing false activations caused by environmental factors. The detector features adjustable sensitivity for both technologies, active IR anti-masking, and selectable pet immunity up to 20 kg, making it suitable for homes with small animals. Its polycarbonate housing is compact and unobtrusive, ideal for residential and commercial applications where aesthetics matter.
