An AOV (Automatic Opening Vent) smoke ventilation system is designed to remove smoke and heat from a building during a fire. It works by automatically opening vents, windows, or louvers when smoke is detected, allowing smoke to escape and fresh air to enter. This helps to keep escape routes clear and reduce the spread of smoke, making it easier and safer for occupants to evacuate and for firefighters to access the building.

AOV smoke ventilation systems are commonly required in multi-story residential buildings, commercial properties, and public buildings, such as shopping centers and schools. They are particularly important in buildings with enclosed stairwells, corridors, and atriums where smoke can accumulate quickly. Local building codes and fire safety regulations will specify which buildings require these systems and the standards they must meet.

AOV smoke ventilation systems should be tested and maintained regularly to ensure they are operational during an emergency. It is recommended to perform weekly visual inspections, monthly functional tests, and annual comprehensive maintenance checks by a qualified professional. Proper maintenance includes checking the condition of vents, sensors, and control panels, as well as ensuring the system responds correctly to smoke detection

It is highly recommended to hire a professional installer for AOV smoke ventilation systems. Professional installation ensures that the system complies with local fire safety codes and standards, and that it is correctly integrated with the building's fire alarm and control systems. Incorrect installation can lead to system failures during a fire, compromising the safety of building occupants and emergency responders.
