Having caught up on this - it makes sense to want a door closer on the outside but before we do that we need to address the locking situation.
As some may know, the current lock takes some force to close, as the act of closing the door tensions a spring which is the force used to unlock it when you scan your fob. This means a door closer won’t work at the moment at all - it’ll not be strong enough to lock the door, and if there is one strong enough, it’ll be really hard to open.
There is a solution…
@Marcus6275 and I have been looking at reinstating the crash bars on the front doors so that it becomes an operable fire exit again. The big push to exit button is not a release button. It requires software to be running and is not the same as green “break glass” buttons.
To get crash bars again (they were take off on moving in to fit the current system), I bought a fail secure (if the power goes off, it stays locked) strike, essentially a latch that can release if powered up. Steve from metalworking fashioned a holder for it and having tested it on the snackspace doors, it will work.
However, before we reinstate the crash bars, we would need to update the entry system software; at present the lock needs a pulse of 0,5s to unlock at which point it’ll remain unlocked forever until someone opens and closes the door, but with the new lock as long as power is applied it’s unlocked and the second power stops, it locks again even if the door wasn’t opened and closed.
I can’t do this software update though - only two people in the space have the ability to update the software on the current lock. The software update needs to be done at the same time as fitting the new lock, so it will require some organisation. Once we get this software update, we can release the lock for 10s giving people enough time to open the door.
We can then fit the crash bar on the left (normally opening) side of the door and strike on the right side (the normally fixed door).
Once we have the new locking setup in place, we can install a door closer to the left door, which will mean that the door will guaranteed close and lock itself.
Tangent - right hand side door
Eventually, to get the right side door fitted with a crash bar, we will need to move the entire access system off the door as it currently obstructs the existing mounting holes.
I’ve been updating the keypad system to accommodate a keyfob reader meaning we could have a replacement already operable, but this will naturally take a while given I’m not in Manchester any more. If someone wants to assist with this, they can mount the square fob reader I have underneath the keypad with the wires coming through the wall to the inside.
