AOV Fault Finding

Need AOV fault finding when vents will not open, panels chatter faults or annual tests fail? Icomply diagnose automatic opening vent and smoke control problems for North West residential and commercial buildings. Methodical tracing from panel to actuator identifies whether the issue is power, wiring, mechanics, weather damage or configuration—so you fix the real cause, not the symptom.

About AOV Fault Finding

AOV faults range from a single seized roof vent to whole-system panel failures after electrical works. Our engineers test standby batteries, output voltages, field continuity, end-of-line supervision and actuator current draw, then inspect hinges, chains and lids for mechanical binding. Temporary isolation of defective circuits can restore partial compliance while parts are sourced. Findings are written up with priorities for the responsible person. Where systems are repeatedly failing, we recommend capital replacement with clear scope. Stockport-based coverage includes Greater Manchester, Cheshire, Lancashire and Merseyside, with reactive attendance and fixed remedial quotes after diagnosis.

●Systematic electrical and mechanical diagnosis of AOV failures
●Panel, battery, wiring and actuator current testing
●Interim risk measures and phased remediations
●Honest upgrade recommendations for end-of-life systems

AOV Fault Finding FAQ

Why did my AOV pass last year but fail now?+

Batteries age, seals stick, water ingress corrodes actuators and third-party works can damage cables. Annual testing is designed to catch gradual failure.

Do you need drawings to fault-find?+

Drawings help but are not essential. We can reverse-trace circuits on site; as-fitted notes improve speed on complex towers.

How quickly can you attend?+

Life-safety faults are prioritised subject to access and capacity. Contract customers can secure enhanced response targets.
