• QEL Quiet electric latch retraction
• The QEL 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. Different than the popular EL, the QEL quiet operation is achieved using an electric drive motor which retracts the latch bolt either momentary unlatching or for extended periods of time.
• The QEL option does not include the power transfer from door to frame, the power supply, or the control operator.
• The PS902/914 power supply with the 2RS, 4RL or 4R board is the minimum required
