Your System is in Safe Hands

A Smoke Ventilation System only protects people and property when it’s in full working order. Keeping your system in operational condition is vital and one of your legal obligations under “The Regulatory Reform Order (Fire Safety) 2005” if you’re responsible for a building.
With expert servicing from PLYMOUTH FIRE PROTECTION, the maintenance of your system is in safe hands and your legal compliance is assured.


Your building's occupants' safety relies on your regular maintenance of the Automatic Opening Ventilation (A.O.V) System. Systems should be serviced and maintained to conform with BS7346, BS9999, BS9991, EN12101 and current Building Regulations Approved Document B. It is recommended that an A.O.V. System is regularly serviced and maintained by specialised personnel on a regular basis.
PLYMOUTH FIRE PROTECTION Maintenance Division provides tailored maintenance schedules to give peace of mind to the buildings owners and occupiers with all preventative maintenance completed to BS7346 and BS9999.


With vital decisions to make, we will advise and support you from the early stages of each project. PLYMOUTH FIRE PROTECTION have experience in project managing all types of smoke and natural ventilation solutions. These cover new build and refurbishment projects of any size or type and are able to adhere to all new British and European Standards.

FACT: Smoke Ventilation Systems save lives. If they are not maintained in accordance with current guidance / regulations, the Management Company or the owners of the premises are legally responsible.

Natural, smoke and heat exhaust ventilation systems must adhere to BS7346 Part 1:1990 & BS 9999 2008. Each site requires a preventative maintenance schedule carried out only by a competent engineer on a 6 monthly basis.

As such PLYMOUTH FIRE PROTECTION provides a range of maintenance contracts, designed to fulfil your most critical requirements in both technical and economic terms.
