1. Install the PMK 550 base plate
a. Using a 5/32 inch hex wrench, remove the four cover
screws from the center of the PMK 550 and slide the two
halves apart. Remove them from the base plate.
N If the PoleVault switcher and its power supply
are already installed, go directly to step 2d.
b. To mount the PoleVault switcher, invert the base plate
and attach the switcher to the plate by inserting the two
supplied 4-40 x 3/16 inch screws up through the plate
and into the top of the switcher. The switcher should be
mounted on the same side as the base plate’s pipe collar.
N The top of the switcher should be secured to the
plate so that when the plate is inverted to hang
from the ceiling, the device will be in its correct
orientation.
Use only the supplied screws to avoid damaging
the switcher.
c. Attach the associated power supply with the supplied
Velcro strap and pads, by passing the strap through the
appropriate slots and around the power supply. Tighten
until snug.
d. Using a 3/32 inch hex wrench loosen the four pipe
collar set screws , and slide the plate up the pipe until
the base plate is touching the drop ceiling.
e. Level the plate and secure it in place with the four set
screws located on the collar, ensuring that a minimum of
three set screws are tightened firmly against the pole.
