Thank you ? I'll definitely make sure the system is properly checked to ensure it's configured properly.

We have no manual controls whatsoever! So a switch is needed at the main entrance to operate the staircase AOV, and switches needed in each lobby to operate the lobby AOVs. Does that mean a switch is not needed at the top of the stairs to operate the staircase AOV? Are you able to point me in the direction of the regulations re this? The contractor we had hoped to use has said we need a control at the top of the stairs and if this isn't necessary we'd like to avoid the additional expense. Interestingly he neglected to say we need controls in the lobbies, so it looks like this is already going to cost more than expected ?. We need to get this right first time! NS

Hi I'm looking for some clarification about the need for and locations of manual smoke vent controls in a four-storey single-staircase property with protected lobbies. Smoke detectors are installed in the lobbies only. On activation AOVs in both the staircase and lobbies open. There is no audible alarm. Where should the AOV manual override switches be located? NS
