Von Duprin QEL3327AEO Surface Vertical Rod Exit Device, Quiet Electric Latch Retraction

Von Duprin QEL3327AEO Grade 1 Surface Vertical Rod Exit Device, Narrow Stile Pushpad, Exit Only, Less Trim, Less Dogging, Quiet Electric Latch Retraction, Non-Handed

Quiet electric latch retraction (QEL)
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.

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 PS902/914 with the 2RS, 4RL or 4R board is the minimum required. Other option boards available for other functions,
see PS902/914 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.
