The MX-23-NBL dual failsafe feature is available only from MICROAXS. Conventional failsafe locking bolts rely solely on a spring to retract the bolt while the MX-23-NBL bolt will unlock with or without the assistance of the spring. This is the only electric bolt lock listed by the California State Fire Marshal for locking of perimeter entrance and emergency exit doors after-hours.
