Smoke Control & Safe Escape

AOV Systems

Automatic Opening Vents that clear smoke from stairwells, atriums, and escape routes — designed, installed, and maintained so people can evacuate safely when every second counts.

Keep Escape Routes Clear

Smoke Ventilation Built for Real Buildings

From a single stair core to multi-storey atriums, SAFECORE designs AOV solutions that open on fire alarm signal, extract or vent smoke, and keep means of escape tenable for longer.

AOV Systems We Design & Install

Smoke control is never one-size-fits-all. We match vent type, location, and control strategy to your building form, fire strategy, and escape routes.

Core

Roof Vents & Skylights

Roof-mounted AOVs and smoke-ventilating skylights that open to release smoke from cores, atriums, and large internal volumes — essential for multi-storey escape.

  • Roof lights & smoke vents
  • Natural smoke ventilation
  • Weather-sealed actuators
  • Manual & automatic control
Popular

Stairwell & Lobby Control

Dedicated smoke ventilation for protected stairs and lobbies so escape shafts stay clearer for longer, supporting phased evacuation and firefighter access.

  • Stair core AOV design
  • Lobby & corridor interfaces
  • Cause-and-effect programming
  • Battery backup where required
Advanced

Façade & Atrium Systems

Window and façade AOVs for atriums, malls, and glazed spaces where smoke layering and air inlet paths must be carefully engineered.

  • Façade window actuators
  • Atrium smoke layering design
  • Inlet & extract balance
  • Integration with BMS options

End-to-End Service

From Strategy to Commissioned System

SAFECORE manages the full AOV lifecycle so vents open when they should, stay closed when they should not, and remain serviceable for years of reliable operation.

Survey & Fire Strategy Input

We review escape routes, shafts, roof access, and existing fire alarm interfaces — then propose AOV positions aligned with your fire strategy and building form.

Supply & Installation

Vents, actuators, control panels, cabling, and weather seals installed by experienced engineers with tidy roof and façade workmanship.

Controls & Cause-and-Effect

Panels programmed so the right vents open on the right fire signal — coordinated with detectors, manual call points, and smoke zones.

Commissioning & Handover

Full open/close tests, fire-alarm interface verification, and clear operating notes for facilities and fire wardens.

Planned Servicing

Scheduled inspections of actuators, batteries, seals, and controls so AOVs remain ready to operate when smoke is present.

Fire System Integration

Link AOVs with fire alarms, emergency lighting, and access release so smoke control supports a complete evacuation package.

How AOVs Protect People

Smoke Control Where Escape Depends On It

Automatic Opening Vents reduce smoke logging in vertical shafts and large voids, helping keep stairwells and routes usable for longer during a fire.

Stairwell Protection

Vent smoke from protected stairs so occupants and firefighters can move with better visibility and cooler conditions.

Atrium Smoke Layering

Roof and high-level vents help manage smoke layers in tall open spaces and multi-level voids.

Fire Alarm Trigger

AOVs open automatically on confirmed fire signals — no reliance on someone remembering a manual switch under stress.

Manual Override

Local or panel overrides support testing, maintenance, and controlled operation by trained staff when needed.

Weather & Security

Systems stay closed and secure in normal conditions, with seals and locking designed for everyday building use.

Battery Backup

Where specified, backup power keeps critical vents operable if mains fails during an incident.

Integrated With Your Fire Alarm

Open Automatically When Smoke Is Detected

A well-designed AOV system is part of the fire strategy — not a standalone gadget. We wire and programme interfaces so the right vents respond to the right zones.

  • Fire alarm zone inputs and outputs mapped correctly
  • Cause-and-effect tested at commissioning
  • Manual control for service and drills
  • Fault monitoring and status indication options

Why AOVs Matter

Smoke Kills Visibility Before Fire Reaches You

Most fire fatalities are linked to smoke. Automatic vents help keep escape routes clearer, support firefighting, and form a critical part of many multi-storey fire strategies.

Building regulations and fire strategies often require smoke ventilation for stairs, atriums, and large enclosed volumes. An AOV system is the engineered response — automatic, coordinated, and testable.

We help developers, landlords, and facilities managers deliver compliant installations with clear documentation, reliable commissioning, and ongoing servicing that keeps systems ready.

Safer Escape

Reduce smoke logging so people can find and use stairs and exits.

Fire Strategy Support

Deliver the smoke control measures your design and risk assessment require.

Firefighter Access

Clearer shafts and approaches for emergency response teams.

Proven Operation

Commissioning and service records that demonstrate the system works.

Where We Work

AOV Systems for Every Environment

Whether you need a single stair AOV upgrade or a full atrium smoke control package, we design around your building and fire strategy.

Residential Blocks

Stair core and lobby smoke ventilation for multi-storey housing and mixed-use buildings.

Offices & Commercial

Atriums, feature stairs, and escape shafts with integrated fire-alarm control.

Retail & Hospitality

Common Questions

AOV Systems FAQs

Straight answers to the questions we hear most often from facilities managers, developers, and building owners.

What is an AOV system?

An Automatic Opening Vent (AOV) system opens roof vents, skylights, or façade windows automatically — usually on a fire alarm signal — to vent smoke from stairs, atriums, and other spaces so escape routes stay clearer for longer.

Do AOVs always need to link to the fire alarm?

In most life-safety applications, yes. Automatic opening on detection or alarm is the core purpose. We also provide manual controls for testing and maintenance. Exact cause-and-effect depends on your fire strategy.

What is EN 12101?

EN 12101 is the European standard family covering smoke and heat control systems, including natural smoke vents and related products. We specify and install solutions appropriate to that framework and your building requirements.

Can you upgrade an existing stair AOV?

Yes. We can replace failed actuators, refresh control panels, improve weather seals, re-programme interfaces, or redesign systems that no longer match how the building is used or what the fire strategy requires.

How often should AOVs be serviced?

Planned periodic inspection and functional testing is essential. Frequency depends on manufacturer guidance, risk assessment, and building use. We offer scheduled service visits with open/close tests and written records.

Do you cover Sussex and the wider UK?

Yes. We design, install, and maintain AOV smoke ventilation systems across Sussex and further afield across the UK. Contact us with your postcode for availability and lead times.
