WHAT WE DO
Automatically Operated Vents
COMMERCIAL & RESIDENTIAL
High Quality AOVs
Automatically operated vents, commonly referred to as AOVs, play a critical role in managing smoke movement within a building during a fire. Smoke is responsible for the majority of fire related fatalities, and in a high rise building the risk of smoke spreading through stairwells, lobbies and corridors is particularly acute given the distances involved and the time required to evacuate occupants from upper floors. AOVs work by opening automatically in response to a signal from the fire detection system, creating a clear path for smoke to escape at high level while drawing fresh air in at low level to maintain a cleaner environment in the escape routes below. This principle, known as natural smoke ventilation, reduces the risk of stairwells becoming untenable and allows both building occupants and firefighters to operate more safely during an incident.

Automatically Operated Vent Installations
The effectiveness of an AOV system is entirely dependent on how well it integrates with the building’s fire detection and alarm system, and how reliably each vent operates when called upon. DRFSC installs AOV systems as part of a coordinated fire strategy, working closely with fire engineers, architects and alarm system designers to ensure that vent positions, opening sizes and control logic are all properly aligned with the overall approach to smoke control for the building. We install and commission systems in accordance with BS 7346 and the relevant parts of Approved Document B, and ensure that all control panels, actuators and override facilities are functioning correctly before handover. Our teams are experienced in the complexities of phased evacuation buildings, where the sequencing of AOV operation must be carefully coordinated with other fire systems to support the intended evacuation strategy.
