Thanks Tom for your helpful reply. I will check that doors latch from when pulled open a few degrees to wide open. That link provides a checklist to use when I inspect the firedoors. Thanks.

Hi A fire door closer needs to be able to latch the door from any angle. Does this include the smallest angle - ie when the latch rests against the strike plate. On inspections I check that our firedoors close from wide range of angles but not this small an angle. Thanks for any replies - I have not found an answer so far by searching the web.
