AOV's (BS7346-8)

At Pyrocel, we don’t just do AOV servicing—we do it properly, professionally, and with the kind of attention to detail that keeps your building safe and compliant.

Automatic Opening Vents (AOVs)—also known as smoke vents—are a critical part of your fire safety system. When there’s a fire, they automatically open to release smoke and heat, keeping escape routes clearer for longer and helping fire crews do their job. But for them to work when it matters most, they need expert servicing.

That’s where we come in.

✅ We carry out thorough inspections, function tests, and preventative maintenance to ensure everything operates exactly as it should.

✅ Whether your AOV system is linked to smoke detectors, fire alarm panels, or manual override switches, we make sure it’s compliant, reliable, and ready.

So if you’re looking for a team that treats your smoke vents with the same care and precision as the rest of your fire safety setup—you’ve found us.
