Cil-y-coed stair and corridor smoke control
Cil-y-coed (Wales, Wales) has a published usual-resident population of 11,720 in 2019. Source: ONS towns 2019. That figure is residents, not a count of blocks with smoke vents. Coastal classification: Smaller non-coastal towns. ONS records population change of 4% 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. Classification on that source: Small. Workplace profile in the ONS towns file: Mixed. Deprivation band on the same file: Low Deprivation.
Manual control at the landing
Residents and the fire service use the manual point, often at stair level, not the panel in a locked riser. We operate that switch as well as the panel output. A vent that only moves from the engineer’s laptop is not commissioned.
Rain sensors lose to a fire input
Comfort mode may shut a vent when it rains. Smoke mode has to win. On a visit we simulate the fire-alarm contact and watch whether a wet sensor still holds the stair vent closed. If it does, the panel logic or the sensor wiring is wrong, and the roof hatch is not a smoke vent until that is fixed.
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 Cil-y-coed.
