AOV repairs and tests in Hyde (Tameside)
Hyde (Tameside) (North West, England) has a published usual-resident population of 35,576 in 2019. Source: ONS towns 2019. That figure is residents, not a count of blocks with smoke vents. Deprivation band on the same file: High Deprivation. Coastal classification: Larger non-coastal towns. ONS records population change of 13% between 2001 and 2019 for this built-up area. Classification on that source: Medium. Workplace profile in the ONS towns file: Residential.
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 Hyde (Tameside).
