Installation Preparation
Installing the NSQ412 is easy as long as you do a little planning before starting. Locate each station within ten feet of
an a. c. power outlet and seven feet of the telephone jacks. The maximum amount of telephone wire that can be
between two stations is 600 feet.
IMPORTANT: Taking full advantage of the system features requires that the telephone number connected to Line 1 be
the same on all stations. If this is not done, the Privacy, Intercom, Page and Transfer will not work properly. In addition,
it is strongly recommended that no other devices operate on Line 1 besides the NSQ412 stations. Any interference on it
can degrade the system performance. The system can be used on a DLS line if either: 1) Line 1 is not the DSL line; or
2) Line 1 wiring connected to all stations is behind the DSL filter port.
There are many different wiring configurations that a telephone jack can have. The station will support both a home run
(the phone line is run from a connecting block to each station) and daisy chain (the phone line is run from one phone to
the next) wiring configuration. Many older homes and businesses have just one telephone line on each jack. Newer
homes and businesses typically have two or three lines per jack. You must identify how your telephone jacks are wired
before connecting them to the NSQ412. If you cannot determine this, call your telephone service provider for assis-
tance.
It is a good idea to document the phone wiring for each NSQ412 location. This can be done using the following work
sheet. Record the telephone number for each line and the jack it is found on for each station.
