Access Controlled Egress Doors
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.
Access controlled egress doors. 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. The access controlled egress doors section is found in both the international building code ibc and nfpa 101 the life safety code. In other words when power fails or the possibility of a fire is. The reason for the change was to help avoid confusion about when this section should be applied.
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. 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. Egress controls will also include a rex that signals the access control system that there is a valid exit. 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. An egress control directly releases the locking mechanism to allow free egress at the door. 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. 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.
If there is a loss of power to the egress control it cuts power to the lock as well. It makes this decision independent of the access control system.
