DynaLock 3101 B Series
DynaLock’s 3101B Series 1500 Lbs. Delayed Egress Holding Force Electromagnetic Locks are designed to satisfy both life safety codes and high security needs. The next generation 3101B system offers better technology, resistance to electrical surges, and a virtually maintenance-free sensing system.
In a typical installation, the door is closed and latched by the existing mechanical door hardware (typically an exit device) and magnetically secured by the 3101B Lock. Attempting to exit by applying 15 pounds or less pressure to the exit device push plate will cause the door to become unlatched, and the pressure and door movement will be sensed by the 3101B internal sensor.
If the pressure is applied beyond the preset nuisance delay of 1 or 2 seconds, it will 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.

SECURITRON iMXDa/ iEXDa
Securitron’s iMXDa Delayed Egress embodies state-of-the-art electromagnetic locking with integrated exit delay. With any attempted exit initiating an alarm and a brief delay before the lock releases, personnel are able to respond before an exit or loss occurs. It is ideal for memory care wards, hospitals, dormitories, airports, childcare facilities and retail or warehouse environments.
The Securitron iMXDa incorporates Securitron’s BondSTAT and Door Position Sensor (DPS) Magnalock® technology along with an intelligent microprocessor, alarm options and a trainable door movement feature. The unit features 1,200 lbs. of holding force, auto sensing dual voltage (12/24 VDC) and provides a variety of easily selectable operating functions.
Installation requires no alteration or replacement of existing latching hardware and the iMXDa is UL listed for use on a fire-rated opening with existing fire-rated latching hardware. Mounting has been simplified with the use of an interlocking mounting bracket.
The iMXDa can be programmed to initiate at a specific range of door movement in a simple one-step operation.
When an occupant triggers the iMXDa by pushing the door to the selected initiation range, he will first trigger a loud audible beeping warning for 3 seconds. After the 3 second period completes, the iMXDa will go into a response time mode featuring a constant audible alarm for 15 or 30 seconds according to code, after which the iMXDa releases the door for egress, the audible alarm stops and the LED changes state to indicate the door is open.
