SMOKE ANGEL PRESSURISATION & VENTILATION SYSTEM
Helping you escape safely!
Where there's smoke, there's fire...
It's a fact... one follows the other.
And left to its own devices, hot toxic smoke can quickly spread and fill a buildings escape routes and trapped people will be unable to breathe or see.
It may be the flames we fear, but more often than not, it's the smoke that kills.
It can quickly spread into escape corridors, lobbies and staircases in residential and commercial buildings rendering escape by those routes difficult if not impossible.
That's why smoke control plays a key role in fire safety and one of the principle life saving solutions is...
PRESSURISATION
...the only accepted method of smoke control where the objective is to prevent smoke entering the escape routes in the first place creating a pressure differential to prevent smoke spread as opposed to naturally ventilating or mechanically extracting smoke from the escape routes and protected spaces.
If the protected spaces stay clear of smoke for occupants to escape, fire service access is enhanced.
Pressurisation is used worldwide as an active form of smoke control which can be applied to all building height although most commonly used on buildings over 8 to 10 storey's where natural ventilation systems for many reasons are unreliable.
DUAL PURPOSE
The Smoke Angel pressurisation system is automatically activated with operation initiated by smoke detectors located within the common corridors or lobbies. The staircase is pressurized with secondary pressurisation of the surrounding areas during the means of escape phase.
Upon fire service arrival the supply fan can be reversed to provide smoke exhaust capacity as appropriate or required for smoke clearance purposes. The Smoke Angel fan being temperature rated for operation at 300ºC for 2 hours.
The Smoke Angel system is suitable for both existing buildings and new build to provide a highly effective and unique form of smoke control.
SYSTEM OVERVIEW
The Smoke Angel is an all-inclusive solution for the stairwell pressurisation and smoke clearance in residential apartment buildings of various heights and layouts with potential effective secondary pressurisation being provided to lobby areas.
The Smoke Angel Systems have been designed and components manufactured to comply with the European Standard EN 12101-6:2005 which has the status of a British Standard. The fans conforms to EN12101 – Part 3 and are CE marked and F300 rated. With the option of an E2 motor in accordance with impending legislation effective from June 2011.
The Smoke Angel is provided with standby power in the control panel and requires a single power supply only.
