KIT - 78 Series Wide Stile Fire-Rated, QEL (Quiet Electric Latch Retraction), Rim Exit Device, 785DT Dummy Pull Trim, 48in, No Dogging, Grade 1, 626/US26D Satin Chrome

The 78-F rim fire exit devices 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.
