Product Overview
Emergency Secure Lockdown Kit for Von Duprin 33A QEL 48" Exit Devices, Visual Indicator, Red with White Icon and "LOCKDOWN" Text, Satin Brass Finish, Field Reversible
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 visual indication assures the occupant the exit device has been put into secure lockdown mode.
An option ideal for high-occupancy spaces such as auditorium-style classrooms with access control, ESL allows occupants to secure an opening in case of emergency.
