Ajax DoorProtect Fibra Black Wired Door & Window Opening Detector

Ajax DoorProtect Fibra Black – Wired Door & Window Opening Detector

The Ajax DoorProtect Fibra is a hardwired opening detector built for reed-switch based intrusion detection on doors, windows, skylights and cabinets. Instead of relying on batteries or radio, it connects to an Ajax Fibra-enabled hub over a simple 4-core cable, giving installers the tamper resistance and reliability of a wired system while retaining the fast setup and two-way communication typical of Ajax devices. Finished in black, it blends into dark door and window frames and suits both residential and light commercial security installations.

Key Features

• Fibra wired technology – a proprietary wired protocol that combines the dependability of a physical connection with app-based remote configuration and two-way communication with the hub.
• Dual reed switches – two independent reed switches improve reliability, so detection continues even if one switch were to fail.
• Flexible magnet placement – the included magnet can be fitted to the left or right of the detector, and two magnet sizes are supplied to suit different mounting gaps.
• Third-party detector input – a normally closed (NC) terminal lets installers wire in an additional third-party detector, such as a vibration or motion sensor, to extend coverage.
• Long cable runs – supports wiring distances of up to roughly 2,000 metres when using standard U/UTP Cat.5 cable, useful for larger properties.
• Anti-sabotage protection – built-in tamper detection reports attempts to remove the detector from its mounting surface or open the casing.
• Fast alarm reporting – triggers and forwards alarm signals to the hub in a fraction of a second, activating connected sirens and notifying users and monitoring stations.
• Line-powered design – draws power directly from the Fibra line, removing the need for batteries and related maintenance.
• Durable construction – rated for a very high number of open/close cycles, supporting long service life on frequently used doors.

Where It's Used

DoorProtect Fibra Black is typically installed on entry doors, ground-floor windows, server room doors, storage cabinets and skylights where a discreet, tamper-resistant wired sensor is preferred over a wireless unit. It's a strong fit for offices, retail premises, warehouses and homes already using an Ajax Fibra wired security setup, particularly where long cable runs or high device density make a wired bus more practical than battery-powered detectors.

Frequently Asked Questions

Does this detector need batteries?
No. DoorProtect Fibra is powered over the wired Fibra bus from the hub, so there are no batteries to replace.

Which hubs is it compatible with?
It is designed for Ajax hubs and modules that support the Fibra wired protocol, such as compatible Hub Hybrid models.

Can I connect another sensor to this device?
Yes. It includes a normally closed (NC) input that allows connection of a third-party wired detector for extra coverage.
