Step 1 Plan Your System
Draw a floor plan of your business, showing the location of the network interface jacks,
where your local telephone lines come into the building or office. Install your controller
close to these jacks. Be sure an AC outlet not controlled by a switch is available.
Show on the floor plan the location of each telephone in your system and the distances of
the wiring run from the controller to each telephone location.
Below is a sample floor plan to guide you in making your own floor plan.
NOTE: If you need to install SPIRIT Commmunications System telephones in another building,
but not more than 1000 feet from the controller, an in-range, out-of-building (IROB) pro-
tection device is required. Contact your AT&T representative and order part number 31304.
INCOMING TELEPHONE LINE
(also called Network Interface Jacks)
NOTE: Be sure cords do not cross hallways. Do not run cords inside air plenums and ducts or
along hot pipes.
Step 2 Check Outlet Grounding
Your SPIRIT Communications System control unit has been protected against AC line
and central office line voltage surges caused by lightning strikes or other power
anomalies, provided the system is properly grounded.
Using a circuit tester, check (or have checked by a qualified technician) the outlet into
which your SPIRIT system control unit will be plugged. If the circuit tester detects
any of these faults, have this corrected before installation of the control unit:
— open ground
— reversed polarity
— open hot
If necessary, have a qualified electrician repair the electrical outlet in the manner
specified by the applicable electrical codes to prevent service interruption and continue
warranty protection. If you have two-wire outlets with no ground wire, a non-switched,
three-wire grounded outlet should be installed.
