Ajax DoorProtect Fibra White Wired Door & Window Opening Detector

Ajax DoorProtect Fibra White Wired Opening Detector

The Ajax DoorProtect Fibra White is a wired magnetic opening sensor built for reliable, professional-grade intrusion detection on doors, windows, skylights, and vaults. Part of Ajax's Fibra wired product line, it combines the resilience of a hard-wired connection with the fast, encrypted two-way communication that Ajax systems are known for. Designed for indoor installation, it pairs with a compatible Ajax hub to deliver instant, addressable alarm notifications the moment a monitored opening is disturbed.

Key Features

• Dual reed switch design: Two independent reed switches detect openings and provide redundancy, so protection continues even if one switch fails.
• Fibra wired protocol: Encrypted, sabotage-resistant two-way communication with the hub, supporting cable runs of up to 2,000 metres over U/UTP Cat.5 cabling.
• Flexible magnet kit: Includes a large magnet (effective up to roughly 2 cm) and a small magnet (up to roughly 1 cm), installable on either side of the detector to suit different door and window types.
• Third-party NC input: An additional normally-closed (NC) terminal lets installers wire in extra motion, opening, or vibration detectors without needing separate power.
• Anti-chatter protection: Built-in filtering reduces false triggers caused by vibration or loose-fitting doors and windows.
• Tamper protection: Onboard tamper switches trigger an alarm if the casing is opened or the unit is forcibly removed from its mounting surface.
• Chime / shopkeeper's bell mode: When paired with a compatible siren, the detector can sound a short tone whenever a monitored door opens while the system is disarmed.
• Fast, addressable alerts: Events are reported almost instantly, identifying the exact device, room, and security group to the user or monitoring station.

Reliable Protection for Doors and Windows

DoorProtect Fibra White is well suited to homes, offices, retail premises, and commercial sites where a dependable wired opening sensor is preferred over battery-powered alternatives. It's commonly installed on entry doors, side and back doors, ground-floor windows, skylights, cabinets, and secure storage such as safes or vaults. Because it runs on the Fibra wired bus, it's an ideal choice for new-build or renovation projects where cabling is already planned, and for sites needing long cable runs, high device counts, or an extra layer of protection against wireless jamming.

Frequently Asked Questions

Does DoorProtect Fibra work wirelessly? No, it is a fully wired detector that communicates with a compatible Ajax hub over a physical Fibra cable connection, not radio.

Can I connect another sensor to this detector? Yes, it includes an additional NC input, allowing a third-party wired detector such as a motion or vibration sensor to be integrated through the same unit.

Which hubs is it compatible with? DoorProtect Fibra is designed to work with Ajax hubs that support the Fibra wired protocol, such as Hub Hybrid models; it is not compatible with standard wireless-only hubs or third-party systems.
