Ajax Superior GlassProtect Fibra

A premium wired glass-break detector in the Ajax Superior / Fibra line, designed for indoor security installations that require reliable, false-alarm-resistant detection over long wired distances. Only accredited partners may install, configure, or maintain these devices. Ajax Systems Support+2ajax.systems+2

Key Features & Functions

• Wired (Fibra) Communication Protocol
  Uses the secure, two-way Fibra bus protocol for fast and reliable alarm/event signaling. Supports data encryption, device authentication, and regular device polling. Ajax Systems Support+2ajax.systems+2

• Glass-Break Detection via Electret Microphone + DualTone Algorithm
  Detects characteristic glass break sounds using a two-step trigger: a low-frequency impact, followed by a high-frequency shattering sound within a short time window. Helps reduce false triggers (dog barks, traffic, etc.). Ajax Systems Support+2ajax.systems+2

• Detection Range and Angle
  Up to ~9 meters detection distance; ~180° horizontal coverage. Fits standard glass pane types of varying thickness (single, insulated, tempered). Sensitivity adjustable in 3 levels. ajax.systems+2ddq.cz+2

• Support for Third-Party Wired NC Contact Detector
  Has terminals for connecting a normally-closed (NC) wired sensor/detector, allowing integration of external sensors (e.g. vibration, movement, opening) on the same module. Ajax Systems Support+1

• High Cable Length over Bus Lines
  Wired signal communication supports up to 2,000 meters over U/UTP Cat-5 twisted-pair cable in radial (beam) topology. For ring topology, the maximum line length is shorter (~500 m). Ajax Systems Support+2Ajax Systems Support+2

• Tamper & Physical Security Protections
  • Two tamper switches: one for opening the housing, another for detachment from the mounting surface.
  • Perforated back-plate part triggers tamper when removing the detector. Ajax Systems Support+1

• Low Power Draw
  Operates with minimal current from the Fibra line. (Quiescent and peak current consumption are modest.) ddq.cz+1

• LED Indicator
  Visual indicator for status, alarms, and tamper events. Helps in installation and service diagnostics. Ajax Systems Support+1

Applications & Use Cases

• Glass-front windows, display cases, shopfronts, and other glass surfaces where fast detection of breakage is needed.

• High-security locations with risk of attempted smashing, vandalism, or break-in via glass.

• Facilities that require wired reliability and sturdy, tamper-resistant hardware for critical points of entry.

• Integrations where both primary event detection (glass break) and auxiliary detection via external wired NC contacts are beneficial (e.g. backing sensors).
