Most fire alarm pull stations (conventional) have dual contacts. 1 can be used to activate the alarm and the other to open the mag ckt.
in your particular case, a relay seems to be the answer.
As far as releasing doors,in older buildings,unless being re-certified,most jurisdictions will not require the release upgrade.
If this is a new install,relays are in order.
Inspired from another site. Re- OSHA standard,Hospitals and such.
"1926.34(a)
"General." In every building or structure exits shall be so arranged and maintained as to provide free and unobstructed egress from all parts of the building or structure at all times when it is occupied. No lock or fastening to prevent free escape from the inside of any building shall be installed except in mental, penal, or corrective institutions where supervisory personnel is continually on duty and effective provisions are made to remove occupants in case of fire or other emergency.
