ELECTRIC EXIT DEVICE KIT INSTALLATION INSTRUCTIONS MOTOR DRIVE ELECTRIC LATCH RETRACTION

1550K-MDP

PRECISION 2000 AND 5000 SERIES

PROVIDES SIMULTANEOUS ELECTRIC LATCH RETRACTION AND DOGGING (TOUCHBAR DEPRESSED)

Installation:

• 1. Separate the device channel from the touchbar assembly.
• 2. Remove the manual dogging components, if present, from the touchbar assembly and discard.
• 3. Remove the manual dogging adjustment screw, if present, from the dogging bar and discard.
• 4. Attach the motor bracket of the 1550K-MDP Kit to the touchbar assembly using the supplied screws through the holes that secured the manual dogging components. Verify the flange of the connecting link is positioned forward of the dogging bar.
• 5. Attach the device channel to the touchbar assembly.
• 6. Install the ratchet clip into the mechanical dogging hole of the filler plate.
• 7. Apply the supplied technical assistance labels to the active case cover and the end cap cover. 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 touchbar 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 touchbar 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 touchbar went from being dogged to unintentionally being extended, and then the touchbar did not retract to the dogged position within 2 attempts.	Clear the jam condition manually.
On	Blink	On	Error in operation. The touchbar 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	Simultaneous Blink		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.
