I don't get into NFPA 72 too much, so I'm hoping someone can help me with this question. Some access control systems for doors are required to be connected to the fire alarm system. For example, when a door has an electromagnetic lock that is released by a sensor which detects an approaching occupant, one of the additional releasing requirements is that the lock unlocks upon actuation of the fire protection system.
A question came up regarding the distance between the access control panel and the fire alarm contact. I found this in NFPA 72:
21.2.4* Emergency control function interface devices shall be located within 3 ft (1 m) of the component controlling the emergency control function.
Is the "emergency control function interface device" the fire alarm contact? And is the "component controlling the emergency control function" the power supply/panel for the access control system? And the actual locks could be installed in remote locations?
Thanks, as always!
