The Recessed Shatterpro II is designed for use when sensor appearance is a consideration. The recessed model can be mounted directly into the wall or ceiling or can be used with the single gang box accessory. A trim ring is included.

Using Sentrol's patented Pattern Recognition Technology, the sensor listens for the actual pattern of breaking glass while eliminating most false alarm patterns. Recessed ShatterPro II sensors listen across the glassbreak frequency spectrum to differentiate the sound of breaking glass from most normal room sounds.

A simple hand-clap feature lets users confirm at any time that the Recessed ShatterPro II is operational.

Features:
- Recessed mounts in a 1" (2.5cm) hole for attractive, unobtrusive appearance.
- Pattern Recognition Technology for superior detection and greater false alarm immunity.
- Eliminates common false alarms by ignoring their patterns.
- Suitable for use in quiet occupied areas on the perimter loop.
- 25' - 360° range.
