The primary function of the EDK is to allow teachers classroom entry control with an adminstrative instantaneous "lockdown" override.  The EDK can also be applied to perimeter and common area openings which may require immediate security when the situation requires immediate prevention of building or classroom entry. 

 

The exit device always allows egress to permit occupants to leave an area while in a lockdown or deactivated mode.  The storeroom function trim requires a key to gain entry.  Optional card and keypad trims are available.

 

 

When the device is de-energized; entry requires use of a key to retract the latch, allowing the door to be pulled open.  After entering the class room, the teacher can activate the EDK feature with the key switch built into the device.  When energized, and after the pushpad is depressed, the pushpad and the latch bolt remain retracted, providing quiet push-pull operation.  The built-in indicator allows the teachers and facility personnel to determine the security status of the device. 

 

 

 

Relocking all devices is accomplished by using either the administrative keyswitch or any of the lockdown pushbutton switches.

Door remains latched until built-in keyswitch is set to the access allowed position and the pushpad is depressed.
