The requirements of the model codes specific to access controlled egress doors are essentially the same but in the 2015 edition of the ibc the section title was changed to sensor release of electromagnetically locked egress doors.
Access controlled egress doors.
The reason for the change was to help avoid confusion about when this section should be applied.
The door has to be able to be opened by releasing hardware attached to the door leaf which is typical of mechanically latched doors and is a requirement for electrically controlled egress doors.
In other words when power fails or the possibility of a fire is.
Access controlled egress doors is found in both international building code ibc and national fire protection association nfpa 101 life safety code as section 1008 1 4 4 and 7 2 1 6 2 respectively.
Egress controls will also include a rex that signals the access control system that there is a valid exit.
If there is a loss of power to the egress control it cuts power to the lock as well.
It is typically applied to doors with electromagnetic locks released by a motion sensor.
The code requirements for access controlled egress doors now called sensor release apply to locks that are unlocked by a sensor which detects an approaching occupant.
It makes this decision independent of the access control system.
Another question we sometimes get relates to standby power.
Access controlled egress doors are a different type of special locking arrangement in which the primary means of releasing the lock is not manual but requires a sensor on the egress side that unlocks the door hardware.
Access controlled egress door assemblies lsc 7 2 1 6 2 and ibc 1010 1 9 9 an access control locking arrangement requires the egress side of the door to be provided a sensor to unlock the door upon detection of an approaching occupant.
It is typically applied to doors with electromagnetic locks that are released by a motion sensor.
Electronically controlled egress nfpa 101 expects all electronically controlled access doors to be fail safe to assure egress.
