It makes this decision independent of the access control system.
Access controlled egress doors.
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.
There are many doors with access control readers that are not required to comply with this section because the hardware allows free egress without the use of a sensor.
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.
In other words when power fails or the possibility of a fire is.
It is typically applied to doors with electromagnetic locks that are released by a motion sensor.
Another question we sometimes get relates to standby power.
Egress controls will also include a rex that signals the access control system that there is a valid exit.
An egress control directly releases the locking mechanism to allow free egress at the door.
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.
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.
Electronically controlled egress nfpa 101 expects all electronically controlled access doors to be fail safe to assure egress.
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.
