Ajax GlassProtect (Jeweller) – Wireless Acoustic Glass Break Detector (White, 9NA)

Product Overview

The Ajax GlassProtect is a miniature wireless acoustic glass break detector designed to protect windows, glass partitions, and display cases across a radius of up to 9 meters (29.5 ft). Using an electret microphone paired with the proprietary DualTone two-factor sound analysis algorithm, it filters out environmental noise (such as barking dogs, passing cars, and thunder) by registering the distinct low-frequency thud of a physical impact followed immediately by the high-frequency ringing sound of shattering glass.

Operating over the proprietary Jeweller wireless radio protocol across open-space distances up to 1,000 meters, GlassProtect delivers immediate alarm alerts in under 0.15 seconds. Equipped with an external wired contact input (NC) for connecting third-party perimeter contacts, Grade 2 certified anti-tamper protection, and a pre-installed CR123A battery providing up to 7 years of autonomous operation, it provides discreet perimeter glass security in a clean white casing.
