Verify On-Site Equipment
Once the equipment installation site is identified and a dedicated AC outlet, earth
ground, adequate lighting and ventilation are available, verify that all equipment
required is on-site and was not damaged during shipping:
Unpacking the KSU - The Key Service Unit is shipped in its own protective carton and
contains the following:
Open the carton and verify that all items are complete and undamaged. Remove all
packing material and store for future use in the event that return shipment is
required. This should be performed at the installer's office with a 48-hour burn-in
period prior to installation.
Check that the type and quantity of boards received is correct. DO NOT unpack the
individual boards at this time.
Verify optional equipment is received and is in good condition.
Verify that a Power Line Surge Protector is on-site.

1. Backboard MDF Installation
A wooden backboard is recommended for all installations and must be installed when
the location has masonry or plasterboard walls. A 1/2 in. plywood material is sufficient for
most installations.
1. Mount the backboard at a convenient height, about 3 ft. above the floor. It can be
bolted in various places to distribute the weight of the system.
2. Space should be available on the bottom side of the backboard for the MDF cabling
and for optional equipment such as a music source and battery backup.
3. It is recommended that the location of each major item be roughly sketched on the
backboard as an installation layout.
4. Locate the Telco-provided CO/Centrex lines at the demarc and extend them to the
MDF location.
