Ajax GlassProtect Fibra White Wired Glass Break Detector

Ajax GlassProtect Fibra White - Wired Glass Break Detector

The Ajax GlassProtect Fibra is a hardwired indoor glass-break detector designed for reliable, tamper-resistant protection of windows, glass doors, and display cases. Using a sensitive built-in microphone paired with Ajax's intelligent DualTone recognition algorithm, it distinguishes genuine glass breakage from everyday household or street noise, keeping false alarms to a minimum. Connected via the secure Fibra wired protocol, this detector suits properties and commercial sites where a cabled security installation is preferred over wireless devices, delivering the dependability of a hardwired system with the smart features of the Ajax ecosystem.

Key Features

• Acoustic glass-break detection: A built-in electret microphone listens for the distinct sound signature of breaking glass.
• DualTone verification algorithm: Confirms an alarm only after detecting both the low-frequency impact sound and the high-frequency sound of shattering glass within 1.5 seconds, dramatically cutting false alerts.
• Adjustable sensitivity: Three sensitivity levels can be configured directly from the Ajax app to match the room and glazing type.
• Up to 9 metre detection range: Covers most standard rooms, retail floors, and showrooms from a single mounting point.
• Secure wired Fibra connection: Uses encrypted, authenticated communication over cable, resistant to jamming and signal interference common with wireless-only systems.
• Third-party detector input: Includes a terminal for connecting an additional wired NC (normally closed) sensor to extend protection.
• Low power draw: Operates on a 24V Fibra line with minimal current consumption, drawing power directly from the control panel.
• Compact, discreet white housing: Slim enclosure blends into most interior décor while housing a tamper-protected case.
• 24-month manufacturer warranty: Backed by Ajax's standard warranty for wired Fibra-line devices.

Ideal Applications

This detector is best suited to homes, offices, retail stores, and showrooms where glass windows, doors, or display cabinets need dedicated break-in detection alongside a wired Ajax security installation. It is particularly useful for installers running structured cabling who want the resilience of a hardwired sensor line combined with Ajax's smart monitoring, sensitivity tuning, and app-based alerts. As an indoor-only device, it is not intended for outdoor or unsheltered installation.

Frequently Asked Questions

Does the GlassProtect Fibra need a battery?
No. It is powered directly over the Fibra wired line from the compatible Ajax control panel, so no batteries are required.

Will normal household noise trigger a false alarm?
The DualTone algorithm requires both a low-frequency impact sound and a high-frequency shattering sound within 1.5 seconds, which helps the detector ignore dogs barking, traffic, or general background noise.

Can I connect another sensor to this detector?
Yes. It has a terminal for wiring in a third-party detector with a normally closed (NC) contact, allowing you to extend detection coverage on the same line.
