Smoke Ventilation That Works When It Matters
An Automatic Opening Vent system is designed to open designated smoke vents, windows or hatches when required by the building’s fire strategy. In the right application, smoke ventilation can help remove smoke and hot gases, support clearer escape routes and assist firefighting operations.
AK Fire Safety supports both new and existing systems, from initial surveys and upgrades through to planned servicing, testing and fault diagnosis.

What an AOV Service Visit Can Include
Every system is different, so the exact maintenance scope depends on the installed equipment, manufacturer information, building fire strategy and site requirements. Typical checks may include:
- Automatic vent and actuator operation
- Control panel status and fault indicators
- Smoke detection and manual control inputs
- Firefighter or emergency override controls
- Standby batteries and power-supply condition
- Fire alarm and other system interfaces
- Cause-and-effect functions where applicable
- Visible damage, obstructions and access issues
- Service findings and remedial recommendations
AOV Fault or Breakdown?
If a smoke-control system is showing a fault or a vent is not operating correctly, contact our team for support. We can assess the issue and identify the most practical next step.
Designed and Maintained Around the Fire Strategy
Smoke-control requirements are building- and system-specific. Relevant references can include BS 7346-8 for the planning, design, installation, commissioning and maintenance of smoke-control systems, parts of the BS EN 12101 series for smoke and heat control equipment, and the applicable building fire strategy and statutory guidance.
The correct approach depends on the premises, system design, fire strategy, manufacturer requirements and any project-specific approvals. We avoid treating every AOV installation as identical and can review existing arrangements before recommending work.
