Automatic Opening Vent (AOV) Systems – Keeping Escape Routes Clear in an Emergency

In the event of a fire, smoke can be more dangerous than flames. Automatic Opening Vent (AOV) systems are designed to clear smoke and heat from escape routes, making it safer for people to evacuate and for firefighters to access the building.

At 24/7 Fire and Security Protection Ltd, we design, install, and maintain AOV systems that are tailored to your building layout, fire strategy, and legal requirements — ensuring your system works exactly when it’s needed most.

Professional Installation – By our trained, DBS-checked engineers.

Commissioning & Certification – Ensuring everything operates as designed and meets compliance.

Ongoing Maintenance – Keeping your AOV system operational and certified year-round.

How AOV Systems Work

When smoke or heat is detected by the fire alarm system, an AOV automatically opens vents, windows, or skylights to release smoke and hot gases. This helps to:

  • Keep escape routes clear and visible.
  • Reduce heat build-up to slow the spread of fire.
  • Improve conditions for firefighting crews.
  • Limit smoke damage to property and contents.

Where AOV Systems Are Required

  • Apartment Blocks & Multi-Storey Buildings – Protecting stairwells and communal corridors.
  • Shopping Centres & Public Venues – Supporting safe evacuation during high footfall.
  • Warehouses & Factories – Clearing smoke from large open areas.
  • Commercial Buildings – Maintaining safe escape routes for staff and visitors.

Protect your premises, staff, and visitors with a professionally designed and maintained fire alarm system.
