This 78 Series Wide Stile Exit Device features Quiet Electric Latch Retraction (QEL), allowing for silent operation in environments where noise reduction is crucial. Certified to ANSI/BHMA A156.3 2014 Grade 1 and UL listed for fire exit hardware, it ensures compliance with safety standards. The RX model includes surface vertical rods and a night latch lever trim, designed to fit doors measuring 48 inches by 84 inches. It offers right-hand reversible handing and can be seamlessly integrated with access control systems or building automation for effortless egress. The QEL functionality allows for momentary or extended latch retraction, providing a modern alternative to mechanical dogging. Crafted in a sleek satin chrome finish, this device not only enhances security but also complements a variety of architectural styles. It features deadlocking latch bolts with a 5/8-inch throw and is designed for durability, equipped with options for rod and latch guards to protect against impact damage. Backed by Allegion services, the Von Duprin RX-QELA-7827L is a reliable choice for professionals seeking high-performance exit devices.

KIT - 78 Series Wide Stile Fire-Rated, QEL (Quiet Electric Latch Retraction), SVR (Surface Vertical Rods) Exit Device, RX (Request to Exit Switch), 780L-NL-06 Night Latch Lever Trim (Requires 1-1/4in Mortise Cylinder), RHR Right Hand Reverse/Reversible Handing (Snap Ring Tool Required), 48in x 84in, No Dogging, Grade 1, 626/US26D Satin Chrome

The 7827-F fire exit surface mounted vertical rod device are certified to ANSI/BHMA A156.3 2014, grade 1 and UL listed for fire exit hardware. Vertical rod and latch guards are available to protect the bottom rod of the exit device from damage by impacts of carts or gurneys passing through doors. Rod and latch guards can be used on hollow metal or tin clad composite fire doors. Quiet electric latch retraction (QEL) provides electronic control of an exit device for environments where limited operational noise is desired. These devices always provide mechanical egress. The electrified latch retraction can also be activated by an access system or building automation system to unlatch the exit device momentarily. Often the QEL is used with a credential reader and access control system to unlock the door momentarily for authorized users. The QEL can also be configured to electronically retract the latch for an extended period of time to allow free entry. This is a convenient alternative to mechanical dogging. If manual dogging required on a panic rated QEL device, the hex dogging option is available, to order specify HD-QEL. The QEL option is available on panic devices and fire rated devices. UL approved for class II circuit applications. The 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 PS902 or 914 power supply. The 900 series power supply with the 2RS, 4RL or 4R board is the minimum required. Other option boards available for other functions, see 900 Series power supply for additional information. The QEL has a low in rush current, so it can be used with standard Schlage power supplies. Calculate the peak current draw of all devices in the system to determine the required amperage of the supply. The -2RS option board is designed to control two electric latch retraction devices and provide time delay between the firing of outputs is required. The power transfer is also sold separately.
