Automatic opening vents for Enniskillen
Enniskillen (County Fermanagh, Northern Ireland) has a published usual-resident population of 14,082 in 2021. Source: Northern Ireland settlement population (published Ireland list, NI jurisdiction). That figure is residents, not a count of blocks with smoke vents. 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.
Actuator swap after the vent will move
Force is in newtons and travel is in millimetres. A replacement that looks similar can stall if the stroke is short or the hinges have dropped. We free a dragging casement before fitting a new chain. Obsolete 24 V bodies are identified from the label.
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 Enniskillen.
