Frequently asked questions
How often should an AOV system be tested?+
AOV systems should be subject to a weekly user test and a full functional service at least twice per year, with annual certification, in line with BS 7346-8.
Can you replace failed actuators and vents?+
Yes — we hold stocks of common actuators, control panels and vent units, and can carry out same-day or next-day replacements where required.
Do you work on residential blocks?+
AOV systems on residential common areas and stairwells form a significant part of our workload, including both new installations and refurbishments.
Will my AOV system integrate with the fire alarm?+
Yes. AOVs are typically interlinked with the fire alarm system to provide automatic activation, with manual override controls at fire service entry points.
