Key Features

• Triple-mode detection
    • Opening detection via dual sealed reed switches (magnet can be mounted on left or right) ajax.systems+1
    • Shock / vibration detection using a built-in accelerometer (multi-level sensitivity) ajax.systems+1
    • Tilt / angle change detection: detects vertical axis deviation to protect windows, skylights, or doors in ventilation mode. Ajax Systems Support+2ajax.systems+2

• External detector input
    Allows connection of a third-party wired normally-closed (NC) detector, providing more flexibility in sensor integration. Ajax Systems Support+1

• Wired Fibra protocol
    Secure two-way wired communication over the Fibra bus. Ensures fast and reliable alarm/event transmission, device authentication, encryption, and protection against spoofing and tampering. Ajax Systems Support+2ajax.systems+2

• Long communication line support
    The device supports wired connection lengths of up to 2,000 meters (using twisted pair U/UTP cat.5 cables) between the detector and an Ajax Fibra hub. Ajax Systems Support+2ajax.systems+2

• Multiple magnet options
    Includes both large and small magnet versions. The small magnet works up to about 1 cm distance; large magnet up to ~ 2 cm (depending on installation axis and whether the surface is ferromagnetic or non-ferromagnetic). Ajax Systems Support+1

• Tamper detection & physical security
    Has two tamper buttons: one for opening the casing, another for detachment from surface. Rear mounting plate has perforated feature to trigger tamper if someone tries to detach. Ajax Systems Support

• Adjustable sensitivity & settings
    Shock sensitivity has multiple levels; tilt angle threshold is configurable (from ~5° up to ~25° depending on settings) by professional or authorized user. ajax.systems+1

• LED indicator
    LED signals device status / events / alarms. Ajax Systems Support

• Compatibility
    Works only with Superior Hub Hybrid (2G) and Superior Hub Hybrid (4G) via the Fibra line. Not compatible with radio-only hubs or wireless range extenders. Ajax Systems Support

Technical Specifications

Applications & Use Cases

• High-security commercial or industrial premises, where door/window intrusion attempts may involve forced entry (shock), partial opening (tilt), or bypassing opening sensors.

• Locations where doors/windows are frequently left ajar (ventilation mode). Tilt detection helps ensure system can be armed while still protecting such compromised openings.

• Installations requiring wired reliability and long cable runs (Fibra line) rather than relying on wireless signals.

• Sites needing integration with other wired NC detectors (external sensors) via the same circuit.

• Projects that require professional, certified installation (Superior / Fibra lines) to meet regulatory or insurance grade standards.
