Mechanical Fire & Smoke Control

Mechanical fire and smoke control is designed to stop the spread of fire and smoke throughout a building, usually to protect occupants whilst they are evacuating or sheltered in place.

Why do you need it?

Buildings that have these systems need to be regularly maintained according to building regulations BS 9991 and BS 9999. Buildings need to have maintained mechanical fire & smoke control to be safe for the users of the building.

With suitable mechanical fire and smoke control in place, your buildings will be protected during the event of a fire and offer the occupants safe passage to the exits of the building.

How do we do it?

Working with various manufacturers of each type of system gives us a unique advantage that we can offer maintenance on different types of systems (even on closed protocol systems).

1, 2, 3, 5- & 10-year contracts ensure peace of mind that your buildings systems are always maintained by a professional team with the skills, accreditations and experience necessary to keep your mechanical fire and smoke control systems operating properly and safely.

Fire Dampers

To stop the spread of fire through compartment walls (normally situated within ductwork). Working by a fusible link, mechanical fire dampers shut in the event of a fire.

MFSD’s

Similar to fire dampers but controlled by an interface linked into the fire alarm which allows the dampers to close on fire alarm activation. Motorised fire and smoke dampers stop the spread of smoke as well as fire.

Smoke Extract Systems

Smoke extract systems are designed to remove smoke from a building in the event of a fire, giving occupants the opportunity to leave the building safely. Extract systems have fans at the top of a mechanical shaft that extracts smoke and stops smoke from travelling to other areas of a building.

Stairwell Pressurisation Systems

Stairwell pressurisation systems are designed to stop smoke entering into a stairwell by fans pressurising an area. This helps occupants evacuate especially when they are using stairwells to exit the building rapidly in the event of a fire.

Smoke Vents

Smoke vents can work on actuators or gas pistons and a manual reset (actuators are common in modern buildings). Smoke vents that work on actuators can be opened and closed as necessary. If these is smoke in a building, smoke vents can be opened and activated remotely to remove smoke.

AOVs

AOVs are automatic opening vents. An automatic opening vent system is a system designed to remove smoke from a building. AOVs are usually used to control the removal of smoke from a building during the event of a fire. When a signal is tripped (such as a fire alarm), an AOV system will automatically open vents, windows and other exits to allow smoke to leave the building safely.
