Von Duprin QELA-7547NL-OP-F-626-48 75 Series Fire-Rated Exit Device with QEL, CVR, 388 Night Latch, Satin Chrome

Von Duprin QELA-7547NL-OP-F-626-48 KIT is a robust exit device designed for narrow stile fire-rated applications. This model features the Quiet Electric Latch Retraction (QEL) for minimal operational noise, making it an ideal choice for environments where discretion is paramount. Certified to ANSI/BHMA A156.3 2014, Grade 1, and UL listed for fire exit hardware, this device guarantees reliable performance in emergency situations. The QELA-7547NL is equipped with a deadlocking latch bolt that provides a 5/8" throw, ensuring strong security without compromising on ease of use. Its field-selectable functions allow for versatility, shipping with exit only, dummy trim, and night latch configurations. The device is suitable for door sizes ranging from 2' 6" to 4', with a centerline height of 39-13/16". Designed for quick electronic control, the QEL can integrate with access control systems, allowing authorized users to unlock the door momentarily. The device also supports features like latch bolt monitoring and request to exit, enhancing its functionality. Finished in a sleek satin chrome, it complements various architectural styles while providing reliable fire-rated protection for your building's exits.

KIT - 75 Series Narrow Stile Fire-Rated, QEL (Quiet Electric Latch Retraction), CVR (Concealed Vertical Rod) Exit Device, 388 Night Latch Cylinder Assembly, (Requires Rim Cylinder), 48in x Up to 96in, No Dogging, Grade 1, 626/US26D Satin Chrome

The 7547-F fire exit concealed vertical rod device are certified to ANSI/BHMA A156.3 2014, grade 1 and UL listed for fire exit hardware. 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.
