AOV Fire Alarm Interface
The AOV fire alarm interface is the link that opens smoke vents when detection confirms a fire — without it, vents may never operate automatically. iComply design, install, test and fault-find AOV fire-alarm interfaces across Stockport and the North West, coordinating cause-and-effect so the right vents open for the right zones under BS 5839 and smoke-control practice.
About AOV Fire Alarm Interface
The AOV fire alarm interface is the link that opens smoke vents when detection confirms a fire — without it, vents may never operate automatically. iComply design, install, test and fault-find AOV fire-alarm interfaces across Stockport and the North West, coordinating cause-and-effect so the right vents open for the right zones under BS 5839 and smoke-control practice.
Interface work includes input modules, relay connections, monitored circuits, double-knock or zone-specific logic where designed, and joint testing with fire-alarm engineers. We clear faults that leave AOVs isolated after alarm engineers’ visits, and document the cause-and-effect matrix for the responsible person. New systems are commissioned end-to-end; existing buildings get surveys when vents fail to respond during fire drills or simulated alarms. Fixed quotes cover cable, modules and testing once the strategy is clear.

AOV Fire Alarm Interface FAQ
Why didn’t the AOVs open during a fire-alarm test?+
Possible causes include missing interface wiring, disabled outputs, wrong zone mapping or panel faults — we trace the signal path.
Who is responsible for the interface — fire or AOV contractor?+
Both sides must work together; we take ownership of the AOV panel end and coordinate joint tests.
Is the interface monitored for faults?+
Good practice is monitored connections so open-circuit or removal of the link raises a fault — we implement as specified.
