Von Duprin 9827/9927 Surface Vertical Rod Exit Device, Exit Only, Electric

Product Overview

Von Duprin 9827/9927 Surface mounted vertical rod device for all types of single or double doors, UL listed for panic exit hardware. Devices are ANSI A156.3 2001 Grade 1. Covers stock hollow metal doors with 86 or 161 cutouts. The 9827 device has a smooth mechanism case and the 9927 device has a grooved case. The surface vertical rod device is non-handed. A fluid damper decelerates the pushpad on its return stroke and eliminates most noise associated with exit device operations on all devices. The Chexit system is designed for use on delayed exit application, ideal for controlled areas. All controls, auxiliary locking, local alarm, and remote signaling are self-contained in the Chexit, providing safe, secure, easy to install and simple to operate door control and exit hardware. Chexit controlled exit device for use on panic or fire exit hardware applications. The Chexit device includes a 6" x 20" decal for application on door, "PUSH UNTIL ALARM SOUNDS. DOOR CAN BE OPENED IN 15 SECONDS." The EL/QEL feature allows for the remote unlatching of exit devices. A control station operator can flip a switch to retract the latch bolt and immediately change an exit door to push-pull operation. Different than the popular EL which uses a powerful, continuous duty solenoid, the QEL quiet operation is achieved using an electric drive motor which retracts the latch bolt either momentary unlatching or for extended periods of time. This feature is an alternative to manual dogging. EL/QEL devices are also useful with automatic door operators, and may be applied to fire-rated applications when under the control of an automatic fire alarm system. UL approved for Class II circuit applications. The EL/QEL option does not include the power transfer from door to frame, the power supply, or the control operator. Refer to EPT-2 power transfer and the PS914 power supply.
