What's confirmed
- Model/MPN: 44392.03.BL1

- Communication: Fibra wired protocol (Ajax's wired hub-and-device architecture)
- Brand: Ajax
Specification note
This listing covers the wired Fibra variant, distinct from wireless DoorProtect models sharing the same product family name — confirm the exact SKU (44392.03.BL1) when cross-referencing against existing Ajax deployments or hub compatibility sheets, since Fibra devices require a Fibra-compatible hub or expander rather than Ajax's radio protocol.
For installers standardising on Fibra wiring across a site, this detector keeps the DoorProtect opening-sensor function on the same wired backbone as other Fibra-line devices, simplifying cable runs and central monitoring through one hub topology rather than mixing wired and wireless zones.
Beyond the confirmed name, MPN and colour above, no further technical specification (detection range, tamper status, operating voltage, dimensions) is available in current listing data — check the Ajax datasheet for 44392.03.BL1 before specifying on a job where these figures are required.
