The 3101B Series is designed to satisfy life safety codes and high security needs at the same time. The next generation 3101B system offers better technology, resistance to electrical surges, and a virtually maintenance free sensing system. The 3121B features a satin aluminum finish.

In a typical installation, the door is normally closed and latched by the existing mechanical door hardware and magnetically secured by the 3101B Lock. Attempting to exit by applying 15Lbs. or less pressure to the door will cause the door to become unlatched, and activate the 3101B 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 3101B is integrated with the building emergency fire alarm system or power is removed. Fire alarm contacts on the 3101B Lock are field selectable for NO and NC signals
