Von Duprin QELA-7847L-NL-F-626-48-RHR-06 KIT is a fire-rated, Quiet Electric Latch Retraction (QEL) exit device designed for high-traffic environments where noise reduction is essential. This advanced system features concealed vertical rods and includes the 780L-NL-06 night latch lever trim, requiring a 1-1/4 inch mortise cylinder for operation. With a right-hand reverse handing and an adjustable length accommodating doors from 48 inches up to 96 inches, this device is versatile and user-friendly. Engineered to meet ANSI/BHMA A156.3 2014 Grade 1 and UL certification for fire exit hardware, the QELA-7847L offers both mechanical egress and electronic control, making it ideal for integration with access systems. The QEL allows for momentary latch retraction, enhancing accessibility for authorized individuals while ensuring secure exits. Constructed with a satin chrome finish, this device not only provides durability but also complements modern architectural aesthetics. The unit’s deadlocking latch bolt features a 5/8 inch throw for added security, while the no-dogging design maintains safety compliance. This product is suitable for various applications, including panic devices and exit alarms, and is designed for hollow metal doors with a thickness of 1-3/4 inches.

Notice: The info below is not item specific.

The 7847-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.
