Mixed-use schemes in Greater London put shops under flats. The smoke control has to match that stack, including sites around Lewisham. See also Catford (0.0 miles), Bromley (3.6 miles), Lambeth (4.2 miles).

Panel, actuator, vent and interface are quoted as separate lines when Lewisham only needs one of them. Full replacements are quoted when the system cannot be kept.

There is no single AOV house brand on this page. SE Controls, Nuaire, Brooks, Geze, D+H, Colt, TROX and the others below are all in scope. The survey says which one is installed.

Cause-and-effect with the fire alarm is tested on the day, including what happens if the signal clears. We do not leave a stair vent that only works from a key switch nobody can find.

Replacement actuators have to suit the vent size and the reveal. A like-for-like guess from a photo is how shafts get the wrong stroke.
