Hi all

 I have an unusual situation with some internal fire doors. We have some doors where we want to restrict access unless it is a real emergency through part of the day, however later in the day we want people to have free access through the doors. The next day it returns to restricted and then later free access again and so on.

 Initially we thought of using break glass, so the door can be used as a fire door, but this then causes a problem when we want free access.

 Is anyone aware of any locks that might accommodate this. I think it is unlikely, but you never know.

 A manager wants to keep the normal single action door lock we have, but just put a small plastic chain with a sign on across the door frame at the restricted times. I’m not keen on this, even though it is feeble plastic it contravenes the single action to open a door requirement.

Thank you all including those that sent PM’s. We have now looked and considered the various electronic systems and key pad override options suggested by you. We have realised because of the setup, whatever physical thing we put on, at whatever cost, we still end up relying on the employees not just overriding the system. These doors have to be a fire door for emergencies at all times, it is just particular occasions we want free / restricted access which may vary day to day. The other odd thing about it is the fire exit route could be in either direction through the doors, depending on where the fire is (which would be easily spotted).

Therefore, if we are relying on people to do the right thing we are thinking we just need to put a sign on the door saying “No access unless in an emergency”. If the sign was metal and hanging on a metal chain on the door (so not blocking the door) and nothing to combust, it should be ok. We then give the employees that may use this a briefing on the sign and why it is there. When later in each day we are happy for free access we simply turn the sign around. We will of course have to ensure it is turned back when needed. We may have to get the signs specially made, but that is ok. I would prefer a red / white sign not green and white, but not sure about that at moment.

I think this will work! and not contravene any fire requirements and be cost effective. Does anyone know of any legal reason this could not be done?

Thanks all for your input, there may be some other areas some of those devices may be useful for.
