Installing the Keypads
Up to 31 addressable keypads (addresses 00-30)
may be used (you may need to use an auxiliary
power supply if the 750mA aux. output is
exceeded). The following keypads may be used:
2-line alpha display, 6139/6160/6160V
NOTE: Refer to the Alpha Vocabulary list found in the
#93 Menu Mode in the Programming Guide for list of
the words annunciated by the 6160V.
To wire the keypads, perform the following steps:
Step Action
Determine wire gauge by referring to the
Wire Run Length/Gauge table below.
Wire Run Length/Gauge Table
Wire Gauge Length
#22 gauge 450 feet
#20 gauge 700 feet
#18 gauge 1100 feet
#16 gauge 1750 feet
1
2 Wire keypads to a single wire run or
connect individual keypads to separate wire
runs. The maximum wire run length from
the control to a keypad, which is homerun
back to the control must not exceed the
lengths listed in the table.
3 Run field wiring from the control to the
keypads (using standard 4-conductor cable
of the wire gauge determined in step 1).
4 Connect the keypad(s) to terminals 6, 7, 8,
and 9 on the control board, as shown in
Figure 3-4.
The length of all wire runs combined,
regardless of the wire gauge, must not
exceed 2000 feet when unshielded quad
conductor cable is used (1000 feet if
unshielded cable is run in conduit, which
acts a shield, or if shielded cable is used).
If more than one keypad is wired to one run,
then the above maximum lengths must be
divided by the number of keypads on the
run (e.g., the maximum length is 225 feet if
two keypads are wired on a #22 gauge run).
