Fire door not opening - fixed

[@brocky78]

Good job I have been asked to look at a stick fire door a dble door can see all latches when I push on either bar top to bottom they all free retract fully go back in place onto little rubber stopper that would otherwise not stop opening when pushed on bars , but still the left door which doesn't have a bar running all the length of the door does not open can move it slightly have checked a similar door in the building from same manufacturer to see while open if there are any hidden bolts which pop out as I push on the bar while the door is open but there are none it is very annoying , any ideas , please? Also on other door the left door one without the bar running length of the door opens on its own without needing second door open , the people working there said it not been opened over a year at least or more , don't want to break the glass pushing to hard !

Look up the make and model installation pdf, that should be a good place to start
