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 New Ollerton.
