Electromagnetic Lock with Door Hardware Release
Type of Lock: This section is specific to electromagnetic locks that are released when door-mounted hardware is operated. The door-mounted hardware may include a lever handle, panic hardware or other device equipped with a request-to-exit (REX or RX) switch or electronic touch sensor.
Code Requirements: The use group or occupancy type must be one where this application is allowed. The door must be equipped with listed hardware mounted on the door leaf, which incorporates a built-in switch to directly release the electromagnetic lock and unlock the door immediately. The release device must have an obvious method of operation and must be readily operated with one hand under all lighting conditions. The code requirements that address this application do not require the lock to unlock upon actuation of the fire alarm or sprinkler system, but the lock must unlock upon loss of power to the switch in the door-mounted hardware.
Common Code Pitfalls: Because this section was added fairly recently, there may be AHJs who are not aware that it is intended to address the specific application of electromagnetic locks released by hardware mounted on the door.
