Von Duprin 967246 (ESL) Emergency Secure Lockdown Kit For 36″ 99 Series Exit Devices

Von Duprin 967246 (ESL) Emergency Secure Lockdown Kit For 99 Series Exit Devices, Less Cylinder

The Von Duprin® Emergency Secure Lockdown (ESL) option is ideal for high-occupancy spaces, such as auditorium-style classrooms with access control. These large spaces often don’t have a way to locally lockdown the room without tapping into the building’s access control system. ESL allows occupants to quickly secure the opening in the case of an emergency.

In the event lockdown is necessary, students or teachers can turn the thumb turn (or cylinder key) of the ESL option installed in the exit device. This action interrupts power to the QEL motor, electronically undogging (extending the latchbolt) to secure pull side of the door as well as sends a signal to the access control system. The status indication assures the occupant the exit device has been put into secure lockdown mode. Free egress out of the room is maintained from the exit side of the door, while access into the room can only be performed with a key.

The ESL can be installed on openings containing both a Von Duprin QEL exit device, and an electronic access control system with credential reader. 1 In addition, where a key cylinder or thumb turn is in use, Von Duprin directional indicators aid the user in determining which way the key or thumb turn must be rotated to secure the opening.
