The V EMERG RELEASE allows emergency access for manual gate operation in the event of power outages.  Normal emergency access is achieved through a limit switch sending on OPEN command to the gate operator when the EMERGENCY Know Box door is opened.  In the event of a power outage a manual lever inside the Knox Box is activated by sending pneumatic pressure to a stainless-steel cylinder mounted to the operator which mechanically pushes the lock solenoid up thereby retracting the locking pin and allowing the gate to be opened manually.  Once the pressure is relived the locking pin will drop back to normal condition. The remote manual release overrides the inherent operator manual release whether is secured with a padlock or not.
