Product Ordered after 7/10/2012 - Product identified by label on QEL motor

You no longer need to use the 900-2Q option board (no longer available) with the PS900 power supplies to operate the QEL+ devices. You can use either the 900-2RS or the 900-4RL boards to operate the new style or current QEL+ device. 

If a customer uses a power supply from another manufacturer, Von Duprin will still warranty all parts and components from the Von Duprin QEL exit device.  The warranty will be voided if the customer uses a power supply that does not meet the specification requirements of the QEL. 

"The new Von Duprin QEL requires a 24 volt, 2 amp regulated power supply. An option board/control switch is still required per the needs of the application, but the new QEL does not require a dedicated -2Q board. The QEL can be powered with any properly working 24V, 2 amp regulated power supply."

The attached table shows the number of QEL+ exit devices that can be used with PS900 series power supplies. An existing 900-2Q will operate the current QEL+ device.
