Commercial smoke control to protect your people and premises 

An AOV (Automatic Opening Vent) smoke control system is required by law – Approved Document B of the Building regulations and BS 9991:2011 – in multi-storey residential buildings, student accommodation. Its main job is to protect stairwells and allow safe evacuation if a fire breaks out.

Keeping halls, corridors, lobbies and stairways clear of smoke in the event of a fire is key to ensuring staff, visitors, residents and guests can escape quickly and safely – while also giving emergency services the best possible visibility. Read on to find out exactly how an AOV system works, and why JLA is best placed to give you full peace of mind across all your fire safety procedures.

Smoke is the biggest killer in fires, and can spread through an entire commercial premises in minutes. Automatic Opening Vents are critical to keeping access areas clear in an emergency, protecting those inside from smoke inhalation and giving them the clearest possible evacuation routes. The automatic extraction vents are also an effective way to reduce heat in a burning building.

What is an AOV system?

An AOV system is designed to empty your building's emergency escape routes of smoke in a fire, and types of vents can range from automated roof hatches and louvres to wall-mounted, end of corridor vents or even internal shaft doors.

Is your business AOV compliant?

In the past, simply fitting a suitable actuator was acceptable way to turn a window into an 'AOV'. In 2013 though, the Construction Products Directive (CPR) stipulated that construction products such as AOVs must be covered by a harmonised European standard (hEN), to be CE marked and tested by a recognised third party.

How do smoke ventilation systems work?

When a smoke detector/sensor or manual break-glass unit is activated within a building, our AOV system's smoke control panel kicks in automatically, opening the vent(s), actuators and vents within the affected area or stairwell to enable swift ventilation. The opening of the AOV quickly clears smoke, allowing those inside the building, particularly on higher floors, safe passage out of the danger area.

Quick, automated smoke control also allows fire fighters and emergency services to move and manoeuvre freely for efficient rescue and recovery.

Benefits of an AOV smoke control system

  • Removes smoke and potentially harmful chemical fumes from the building (replenishing oxygen and reducing Co2 levels)
  • Regulates temperature and humidity by circulating cool, clean air around evacuation routes 
  • Improves visibility to allow fire service and paramedics to do their jobs, get to any trapped individuals more easily and attack the fire quickly
  • Helps Fire Incident Commanders (and your own Responsible Person) to implement the most efficient fire evacuation and incident plan
  • Limits damage to property structure and contents
