About this product

Overview AJAX GlassProtect Jeweller is a compact wireless glass-break detector for indoor Ajax security systems. Its electret microphone listens for the characteristic sounds of impact and shattering glass, providing detection from 0.3 to 9 m across a 180° horizontal angle. Two-Stage Glass-Break Verification The DualTone algorithm checks for a low-frequency impact followed by the high-frequency sound of breaking glass within 1.5 seconds. This two-stage verification helps reduce false alarms from unrelated sounds, rather than treating every loud noise as a break-in. Adjustable Sensitivity Three sensitivity levels can be configured in the Ajax app by an authorised user or installer. Detection testing during installation helps establish suitable positioning and settings for the room. Important Glass Compatibility Limitation The detector does not detect glass breaking when the glass is covered with shockproof, sunscreen, decorative or any other film. A different detection solution is required for film-covered glazing. Additional Wired Detector Input Terminals support a compatible wired detector with normally closed contacts, allowing an existing opening, motion or vibration detector to
