Internal Fire Door - Coded Locks

[Guest TomRankin]

Hi there,

I work at a gym and we need to put some security on our changing room doors. They are both fire doors and there are fire routes leading from inside the changing room out of them. I want to put a coded lock on the door which will have a handle on the inside to allow exit. Is this permitted with it being a fire route? Does the handle have to be a certain type, size etc? 

Thanks in advance for your help!

This would comply to  BS EN 179 - Emergency exit devices - with a code needed to get in, but a simple push to exit

Be mindful that installation of a codelock could possibly affect the fire resisting performance of the door.
