Statistics reveal that 90 percent of fire related fatalities are dued to smoke poisoning from fires within structures. The importance of smoke vents and SHEV systems, therefore, could not be underestimated.

The SHEV system and smoke vents also permit fire fighters and first -responders to enter the location, meaning that passages are sufficiently clear for them to attend to occupants in need as well as get to the resource of the fire in order to extinguish it.

After detection of smoke, these AOVs will certainly open up automatically via electrical actuators (electric motors) or magnetic locks. Firefighters are given the ability to bypass this system at various manual call points placed throughout the structure. A system such as this will certainly be connected to a main control board as well as a battery data backup, ensuring that the SHEV will certainly function also if the keys supply falls short.

There are several various feasible locations for automated position smoke vents, consisting of: the automated position window, which launches smoke right into the atmosphere; the smoke shaft and AOV, where smoke flows via a window or door to the vent then out right into the atmosphere; and the stairwell AOV, where smoke flows though an AOV on top of a stairwell.

Also in the lack of a natural smoke vent system, this permits improved safety conditions allowing occupants to leave the structure and firefighters and first -responders to access the scene and accomplish their job quickly and efficiently.
