Em-Vent electrically operated smoke vents are designed to reduce smoke build-up, thus providing a safer escape route for occupants, and access for fire-fighting personnel. The system can also be utilised to provide natural ventilation.
A typical smoke ventilation system includes opening vents (OVs) or automatic opening vents (AOVs) located at the highest point of an escape route staircase or at the top of a smoke shaft. Smoke detectors and manual control points are normally located on each floor.
The system can be controlled by the Em-Vent Control Panel, ideally suited to stand-alone
smoke vent installations. In the event of a fire, the smoke detectors on the relevant floor instruct the control panel to operate the automatic opening vents, creating an upward air flow, venting smoke and toxic gases.
Em-Vents can be supplied with the Em-Dome glazed rooflight, bringing the added benefit of natural daylight into the building.
