The 3101C Series is designed to satisfy egress codes and high security needs at the same time. The next-generation 3101C system integrates totally-redesigned and updated electronics with DynaLock's proven and forgiving egress-sensing technology. In a typical installation, the door is normally closed and latched by the existing mechanical door hardware and magnetically secured by the 3101C Lock. Attempting to exit by by unlatching and pushing on the door will activate the 3101C delay egress timer. The audible and red LED will pulsate for 15 seconds (30 seconds field selectable). After the time delay has elapsed, the lock will release and the audible will sound continuously with a green LED, until the door is shut and the lock is reset. Reset and/or bypass are accomplished with a built-in keyswitch or remote signal. The system unlocks automatically when the 3101C is integrated with the building emergency fire alarm system or power is removed. Fire alarm contacts on the 3101C Lock are field selectable for NO and NC signals.
