THASE ENTERPRISE 8000 SERIES HAGER 4500 AND 4600 SERIES PDQ 6200 SERIES

STANLEY COMMERCIAL QED100, QED200 AND QED300 SERIES

PROVIDES SIMULTANEOUS ELECTRIC LATCH RETRACTION AND DOGGING (PUSH BAR DEPRESSED)

Installation:

• 1. Separate the mechanism case from the baseplate assembly.
• 2. Remove the manual dogging assembly, if present, from the baseplate assembly and discard.
• 3. Attach the mounting plate of the 1550K-MDT Kit to the baseplate assembly using the supplied screws and lockwashers through the holes that secured the manual dogging assembly.
• 4. Attach the connecting link to the center link of the baseplate assembly using the supplied clevis pin and retaining rings.
• 5. Attach the mechanism case to the baseplate assembly. Verify the flanges on the motor bracket are located with the baseplate assembly in the same mounting grooves of the mechanism case.
• 6. Install the ratchet clip into the mechanical dogging hole of the cover plate.
• Apply the supplied technical assistance labels to the chassis cover and the end cap. Do not remove any regulatory labels adhered to the device.

Motor Drive Electric Latch Retraction Adjustment:

• 1. Verify the device is properly adjusted for mechanical operation. Electric operation should not exceed the mechanical operation or there will be a high risk of damage to the device. We suggest setting the latch retraction under electric operation at 1/16" less than the latch retraction under mechanical operation.
• 2. Locate the adjustment screw in the rear of the motor assembly. Rotate the adjustment screw clockwise to increase the latch retraction or counterclockwise to decrease the latch retraction.

Onboard Indicator Light Assignments:

Maintain input power to the exit device and check the onboard indicator lights.

Remove input power before attempting a solution.

Green (Power)	Yellow (Sensor)	Red (Error)	Indication	Possible Solution
Off	Off	Off	No Power.	Connect the wiring between the power supply and the exit device.
On	On	Off	Normal Operation. The push bar is retracted to the dogged position and dogged; the latch is retracted by default. The device is allowed 2 attempts.
On	Off	On	Error in operation. The push bar did not retract to the dogged position within 2 attempts.	Rotate the adjustment screw counterclockwise to decrease the latch retraction.
On	On	On	Error in operation. Without power being removed, the push bar went from being dogged to unintentionally being extended, and then the push bar did not retract to the dogged position within 2 attempts.	Clear the jam condition manually.
On	Blink	On	Error in operation. The push bar did not extend from the dogged position when the power was last removed. The device will not attempt a retraction.	Clear the jam condition manually.
On	Blink	Simultaneous	Error in operation. The input voltage dropped below the specification during operation.	Decrease the wire run or increase the wire gauge.
On	Alternating Blink		Error in operation. An electronics fault was detected.	An electronics replacement is required.
