SEPARATION OF CIRCUITRY
Non power limited inputs and Class 2 outputs need to maintain a minimum 1/4" to comply with NEC power separation requirements.

Up to two latch retraction devices can be used with the 782. If only one device is to be used, wire to the “DEVICE ONE” location at
TB3, terminals 7 and 8.
Note: When using 7000P or Corbin Russwin ED4000/ED5000 x M94 series exit devices with red and black leads, be sure to observe
polarity when connecting “DEVICE ONE” and “DEVICE TWO” to TB3. (Refer to the wiring diagram located on the lid of the controller.)
THEORY OF OPERATION
7000P Series Exit Device (Electric Latch Retraction) or Corbin Russwin ED4000/ED5000 Series Exit Device x M94 (Latch Pullback)
The 782 operates at two states. The rst, initial, state delivers a high energy retraction force to the solenoid. This initial retraction
force requires a high inrush current of several amps. Once the solenoid is fully retracted, the device switches to a low power holding
state requiring less than an amp. The device stays in this holding state until power is removed and the device disengages.
STANDARD OPERATION
The 782 provides a choice of two methods of electric latch retraction: Paired or Independent System.
PAIRED SYSTEM LATCH RETRACTION
This method allows one input to control two devices sequentially for use on double door applications. A momentary switch closure
across terminals 15 and 16 of TB3 will pull back DEVICE ONE rst, followed by DEVICE TWO. Use this method for a pair of doors using
devices on both leaves. The 782 comes from the factory already set up for this method. Jumper PJ1 should be set to “Paired” for this
mode of operation.
