Installation
Attach Brake to the Control Station (Key Lock Box)
To prevent possible SERIOUS INJURY or DEATH from a closing door:
• The constant-pressure-to-close switch MUST be installed within sight of the door, out of reach of children, at a minimum height of 4.92' (1.5 m) and
away from ALL moving parts of the door.
• The constant-pressure-to-close switch MUST NOT be accessible to the public.
• Install the entrapment warning placard on wall next to the control station in a prominent location that is visible from the door.
1. Determine the mounting location for the control station. Remove the brake handle from the brake release cable. Locate the end of the dead shaft where the
brake and power cables will be pulled through. If there is a solid mounting plate or obstruction at the end of the shaft, drill a 1/2" (12.7 mm) or larger hole
through the end plate, making sure the hole being drilled makes it through the center of the shaft. Feed a fi sh tape through the end of the shaft to the hole
drilled just past the rear of the motor. Connect the brake and power cables to the fi sh tape.
2. Pull the brake cable and power cable wires through the 1/2" (12.7 mm) hole that was drilled in the dead shaft behind the motor and down to the desired
location of the lock box.
3. Run the brake cable and door control wires to the lock box location. Insert the brake cable through the rear knock out and secure to the brake release arm
with the hex socket plug and aluminum drum. Check that the brake line is installed correctly by pulling the brake lever to release the internal brake clutch.
The door should open manually. If the brake did not release, tighten brake cable. Release the hex socket plug, pull the brake line to create more tension.
Reset the hex socket plug.
4. Fasten the entrapment warning placard next to the lock box.
