Batteries, not a green LED
AOV panels are supposed to open the vents after the mains has failed. We check battery date, charge voltage and whether the connected actuators still move on batteries. A silent fault LED after a reset is not evidence the standby supply can throw a roof vent.
Shafts are a sequence
A smoke shaft works only if the inlets and the outlet open in the combination the design states. Opening the head vent while every lobby damper stays shut is not a pass. We do not enter a shaft that has no safe access, and we write “not accessed” rather than “satisfactory”.
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 Northfleet.
