Portadown stair and corridor smoke control
21,097 people were the published usual residents of Portadown in 2021. The place sits in County Armagh, Northern Ireland. The source line is Northern Ireland settlement population (published Ireland list, NI jurisdiction). Classification on that source: Settlement. Fire safety law and building regulations in Northern Ireland are not the English Approved Document B set. We quote to the strategy and the rules that apply there, and we say so on the visit record.
Natural vents and fans are different machines
A chain actuator on a stair window is a natural ventilator, usually talked about under BS EN 12101-2. A car-park or basement extract fan is powered smoke control, usually BS EN 12101-3. We will not price one as the other. The phone call has to establish which machine is actually on the building.
The fire-alarm contact is a named input
Most stair vents should open from a volt-free contact the cause-and-effect describes, often fire in the stair or a lobby, not “any device in the building”. We test the input the drawing names. After an alarm-panel change, that relay is the first thing that goes missing.
Automatic opening vents are life-safety smoke control, so this sits with fire protection and is quoted across the UK. Population figures are the published resident counts named above. They are not a survey of vents in Portadown.
