Dynalock 3121B-DSM2-LP2 Delay Egress System Electromagnetic Lock, Double Outswinging Door, Double Coil, Satin Aluminum

The Dynalock 3121B-DSM2-LP2 is designed to satisfy life safety codes and high security needs at the same time. The next generation 3121B system offers better technology, resistance to electrical surges, and a virtually maintenance free sensing system. The unit features a satin aluminum finish.

The 3121B-DSM2-LP2 is designed for double outswinging doors and does not feature a center mullion. The unit is equipped with a door status switch and a low power coil.

In a typical installation, the door is normally closed and latched by the existing mechanical door hardware and magnetically secured by the 3121B Lock. Attempting to exit by applying 15Lbs. or less pressure to the door will cause the door to become unlatched, and activate the 3121B 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 3121B is integrated with the building emergency fire alarm system or power is removed. Fire alarm contacts on the 3121B Lock are field selectable for NO and NC signals.
