A typical Delayed Egress application would be an Alzheimer’s wing in a hosptial or in a nursing home. The system is designed to allow a person to exit, but only after a 15 second delay with an alarm sounding. This allows time for a nurse or assistant to arrive at the door before it unlocks.
Most often, you will find exit bar hardware on the door as well. This helps secure the door. But it also makes an inviting device for people to push whether they knowingly want to exit or not. In most cases, people simply walk up to the door and press on the bar because that is what it looks like they are supposed to do. The pressure they put on the door activates the Delayed Egress lock by sounding an alarm and also starting the timer count down from 15 seconds to zero. At zero, the door will unlock.
Some cities allow a 30 second delay and the 3101B will accomodate this time as well. The timer is field selectable for either 15 or 30 seconds.

Microprocessor Controlled: An advanced digital processor on-board manages all lock functions, without the need for an external system controller. Custom factory programs are available to meet varying job requirements and local building codes.
Low Installation Cost: The user friendly micrometer style adjustment wheel simplifies calibration of delay egress sensor and works with existing door hardware. Does not require touch or electrified exit devices, electric hinges, door cords or special power supplies.
Watchdog Circuit: Will signal malfunction with pulsating LED and audible for maximum dependability.
Selectable Nuisance Delay: 1 or 3 second to deter false alarms.
Opto-Electronic System Sensor: Featuring a new concealed optical sensor unaffected by wind, warpage or door sag.
Holding Force: 1500 Lbs. high security holding force per lock effectively deters forced access or egress.
Lifetime Warranty: American Made in the USA by DynaLock, with over 20 years experience in the manufacture of electromagnetic locks.

From The Manufacturer . . .
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.
