Smoke vents and automatic opening vents (AOVs) are important facets of smoke safety systems. They should be installed in all commercial buildings where the fire regulations say that they are required. Often, they can be installed anyway to make a building even safer. They can all be linked together with the rest of the fire safety system in order to make sure all the different parts are working together to ensure the ultimate protection for people inside a building.
AOVs can be linked up to fire alarm systems and will open when they sound. They can be set to open in other situations as well, creating a way for smoke to exit a building. Smoke vents perform much the same function. AOVs might also be used for access to a roof area or another hard to reach part of the building, making it easier to get in and out.
