Fire Detection System · Fire Fighting
Autronica BD-31 Optical Smoke Detector is a fire detection system. It is installed in protected spaces or the fire-detection control area according to the vessel's approved fire-detection plan. Its purpose is to detect or manually report fire conditions and transmit the corresponding alarm and location information to the bridge or fire-control station. Detector technology, loop architecture, address configuration, voting logic and interfaces depend on the exact approved system. The exact model designation distinguishes detector or panel function, loop compatibility and approval from neighboring fire-detection components; refer to the manufacturer documentation for the exact figure.

What our service work and the manufacturer documentation say about keeping this model running.
Inspect detectors, call points, panels, loops, power supplies and interfaces according to the approved fire-system test plan. Keep sensing openings clean and protect devices from paint, steam and dust during maintenance. Function-test alarms, zone identification, sounders and required output relays using approved test tools and procedures. Check backup batteries and power-failure indications and record any isolated zone or disabled device. Restore all bypasses and isolations after work. Refer to the manufacturer documentation for the exact figure for test frequencies, detector limits and replacement procedures.
Keep approved detector heads, bases, manual-call-point elements, loop modules, fuses, batteries, relays and selected panel components compatible with the installed system. Replacement devices must preserve addressing and type approval. Maintain approved test tools and detector-specific service accessories.
