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
•
1A aux. output is exceeded (for Canada 650mA).
Use a 2-line alpha display, 6160CR-2 (for fire only) or 6160 (for burglary only).
•
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
#22 gauge
#20 gauge
#18 gauge
#16 gauge
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 keypad(s) to terminals 11, 12, 13, and 14 on the control board, see Figure 3-5.
NOTE: In a Fire Application and when using only one keypad, it must be connected to Keypad Port 2, and must
be mounted within 20 feet of the cabinet wired in conduit. The keypad on Port 2 is electrically isolated from
those on Port 1 and will continue to function even if wiring problems prevent the other keypads from working
properly.
• 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).
