3121C DynaLock Electric Strikes, Bolts, Magnet

The 3121C Series is designed to satisfy life safety codes and high security needs at the same time. The next generation 3121C system offers better technology, resistance to electrical surges, and a virtually maintenance free sensing system. In a typical installation, the door is normally closed and latched by the existing mechanical door hardware and magnetically secured by the 3121C Lock. Attempting to exit by applying 15 Lbs. or less pressure to the door will cause the door to become unlatched, and activate the 3121C 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 key switch or remote signal. The system unlocks automatically when the 3101B is integrated with the building emergency fire alarm system or power is removed. Fire alarm contacts on the 3121C Lock are field selectable for NO and NC signals.
