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. You will want to install your
controller close to these jacks.
Show on the floor plan the location of each telephone in your system. Also show the
distances of the cable run from the controller to each telephone location.
Below is a sample floor plan to guide you in making your floor plan.
NOTE: If you need to install SPIRIT Communications System telephones in another building
an in-range, out-of-building (IROB) protection device is required. Contact your AT&T
representative and order part number 31304.
INCOMING TELEPHONE LINES
(also called Network Interface Jacks)
NOTE: Be sure cords do not cross walkways. Do not run cords
inside or on top of 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 the following faults, have them corrected before installation of the control unit:
— open ground
— reversed polarity
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.
