The Extron PMK 550 Pole Mount Kit, designed for use with the Extron PoleVault™ System, allows for easy mounting of PoleVault
products to a projector pole. The PMK 550 is compatible with both the PVS 204 series and PVS 305 series of PoleVault switchers.
When installed it mounts the PoleVault system switcher, the associated power supply, and an accessory device within an
enclosure below a suspended ceiling.

Items included in the kit are:
Covers (2), Base plate (1), Mounting plate (1),
Tie wraps and pads (to secure power supply),
4-40 Screws (to mount devices) (3), Cover Screws, (4)
NOTE: For full device installation, configuration,
menus, connector wiring, and operation
details of the PoleVault switcher, see the
relevant PoleVault System Installation Guide
available at www.extron.com.
Installation
To install the PMK 550 in a PoleVault system:
1. Remove the four cover screws from the center (see gure 1).
Slide the two halves apart and remove them from the base plate.
NOTE: If the PoleVault switcher and its power supply are
already installed, go directly to step 5.
2. To mount the PoleVault switcher, place the mounting plate, with the
raised tabs upwards, on top of the switcher top and pass the two
supplied 4-40 x 3/16 inch screws into the top of the switcher (see
gure 2, top). Secure the mounting plate but do not overtighten.
3. Hook the combined plate and switcher into the PMK 550 base plate.
Secure it to the base plate with two screws.

NOTES:
• Any installed switcher should be secured to the plate
in an upside down position so that when the plate is
rotated to hang from the ceiling, the device will be in
its correct orientation (see gure 2, bottom).
• Use only supplied screws to avoid damaging the
switcher.
4. Attach the associated power supply with the supplied tie wraps and
pads, by passing them through the appropriate slots and around the
power supply (see gures 2 and 3). Tighten until snug.
