Von Duprin LXQEL3347AL Concealed Vertical Rod Exit Device with 360L Trim, Quiet Electric Latch Retraction, Latchbolt Monitor

Von Duprin LXQEL3347AL Grade 1 Concealed Vertical Rod Exit Device, Narrow Stile Pushpad, Classroom Function, Lever with Escutcheon, Less Dogging, Quiet Electric Latch Retraction, Latchbolt Monitor

Latch bolt monitoring (LX)
The LX feature is used to signal the use of an opening. This device is equipped with one internal SPDT switch which monitors the latch bolt. The device can be connected to a security console, or may be used as a single door alarm when used with a horn and power supply. A continuous current electric transfer must be used for transferring power from the frame to the door.

The LX switch option should not be used to control a load, but as a signalling switch (0.5 amps. resistive maximum).

The LX switch is available in a low current (LC) switch. Most commonly used in computer operated monitoring systems.

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.
