Low and high-rise residential apartment blocks will house a large number of tenants where it is vital to their life safety that the AOV system is not only maintained but upgraded as necessary to suit todays regulations. Similarly, schools and offices may need frequent remedial AOV work.

As most AOV servicing is done by fire alarm companies, an AOV specialist would be required when a fault in the AOV system has occurred which can’t be understood by the company servicing the system.

In these cases, an independent smoke ventilation expert must ensure the correct repairs are undertaken and the correct regulations are followed. Once checked and handed over, a valid AOV commissioning certificate will be issued.
