AOV repairs and tests in Port Talbot
Port Talbot (Wales, Wales) has a published usual-resident population of 38,104 in 2019. Source: ONS towns 2019. That figure is residents, not a count of blocks with smoke vents. Classification on that source: Medium. Workplace profile in the ONS towns file: Working. Deprivation band on the same file: High Deprivation. Coastal classification: Larger other coastal towns. ONS records population change of 7% between 2001 and 2019 for this built-up area. Wales has its own building regulations. A smoke vent is still judged against the fire strategy for that building, not against an English town page.
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 Port Talbot.
