Frequently Asked Questions

What is a Brett Martin Mardome Smoke Vent (AOV)?

A Brett Martin Mardome Smoke Vent (Automatic Opening Vent, or AOV) is a specialised roof dome designed to open automatically during a fire. Connected to a smoke detection system or fire alarm control panel, it exhausts heat and smoke out of the building to keep escape routes clear and reduce structural damage.

Are Brett Martin Mardome smoke vents compliant with UK Building Regulations?

Yes. All Brett Martin Mardome AOV smoke vents are fully tested and certified to BS EN 12101-2 standards, ensuring full compliance with UK Building Regulations Approved Document B (Fire Safety) and Approved Document L (Conservation of Fuel and Power).

What components do I need for a complete smoke vent installation?

A complete AOV smoke vent installation typically requires:

  1. Mardome AOV Smoke Vent Roof Dome (with integrated actuator mechanism).
  2. AOV Control Panel (5 AMP or 8 AMP, supplying backup battery power).
  3. Fireman’s Priority Switch / Break Glass Unit (for manual override by emergency services).
  4. Optical Smoke Detector (for automatic localised triggering).

Can Mardome smoke vents be used for daily comfort ventilation?

Yes. Mardome AOV systems can be configured with dual-purpose controls, allowing the rooflight to open partially for daily background ventilation while retaining full emergency priority override in the event of a fire.
