Electrified Options
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. 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.

QEL Electrical load
Voltage: 24VDC
Current: 1.0 A Inrush (0.5 sec.) / 0.14 A Holding / 2.0 A Calibrate (3 sec. one time)

Electric latch retraction (EL)
The EL feature allows for the remote unlatching of exit devices. A control station operator can flip a switch to retract the latch bolt and immediately change an exit door to push-pull operation. A powerful, continuous duty solenoid retracts the latch bolt, either for momentary unlatching, or for extended periods of time. The EL feature is an alternative to manual dogging.

EL devices are also useful with automatic door operators, and may be applied to fire-rated applications when under the control of an automatic fire alarm system. UL approved for Class II circuit applications. The EL option does not include the power transfer from door to frame, the power supply, or the control operator.

Solenoid specifications:
Continuous duty – 24 VDC 
Current inrush – 16 amps
Current holding – 0.3 amps

Solenoid resistance:
-grn-yel 1.2 – 2.2 OHMS
-grn-org 100 – 150 OHMS

Switches
Request to exit (RX)
The RX feature is used to signal the use of an opening. This device is equipped with one internal SPDT switch which monitors the pushpad. 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 electrictransfer must be used for transferring power from the frame to the door.

The RX switch option should not be used to control a load, but as a signalling switch (0.5 amps. resistive maximum). The RX switch is available in a low current (LC) switch. Most commonly used in computer operated monitoring systems.

Double request to exit (RX2)
The RX2 feature uses two RX switches.

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.

Electrical rating for all switches
1. Standard – 2 amp maximum @ 24VDC
2. Low Current (LC) - below 50 Milliamps @ 24VDC
