Door lock thumbturn or door release button

[Guest George]

Hello,

We live in a block of 15 flats and have a communal main front door. 

Currently there is a door release button next to this communal door, so we can exit the building without using a key to get out.  Good for getting out in an emergency situation and for every day use too..

My question is .. would a thumbturn lock on the door also be required or is the door release button sufficient? 

Thanks very much,

George

I am assuming this door is locked using a magnetic lock therefore it is subject to BS 7273-4 and requires a manual release  which looks like a manual call point box but coloured green. Check out the above BS for more information.

Thanks Tom for the suggestion.
