Section 5:
INSTALLING THE KEYPADS
This section provides the following information:
•
A list of wired keypads that may be used
•
Instructions for wiring and mounting the keypads
•
Instructions for addressing the keypads
•
A preliminary check-out procedure to ensure that the keypads are
functioning properly in the system
Keypads That May Be Used
•
Two Line Alpha Display: 6139 (gray) or 6139R (red) (check with local AHJ for
approval of keypad color)
•
Up to 16 addressable keypads may be used in the system, independent of
auxiliary power considerations (you may need to use an auxiliary power
supply if the 1 amp aux. output is exceeded)
Wiring To The Keypads
1. Determine wire gauge by referring to the wiring length/gauge chart below.
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
home-run back to the control must not exceed the lengths listed in the table.
Wire Run Length Table

Length
#22 gauge
450 feet
#20 gauge
700 feet
#18 gauge
1100 feet
#16 gauge
1750 feet
1. The length of all wire runs combined must not exceed 2000 feet when
unshielded quad conductor cable is used (1000 feet if unshielded cable is run
in conduit or if shielded cable is used.)
2. If more than one keypad is wired to a run, then the above maximum
lengths
must be divided by the number of keypads on the run (i.e. the
maximum length
would be 225 feet if two keypads are wired on a #22
gauge run).
3.
Run field wiring from the control to the keypads (using standard 4-conductor
cable using the wire gauge determined in step 1).
4.
If using only one keypad, it may be connected to either Keypad Port 1 or 2,
and must be mounted on or within 3 ft. of the cabinet. If using multiple
keypads, connect one to Keypad Port 2 and mount it on or within 3 ft. of the
cabinet. Set the main keypad to an address of 00 (this address cannot be
disabled in programming). Additional keypads can be mounted where
desired and must be connected to Keypad Port 1 terminals (11, 12, 13, 14),
as shown in Figure 4. 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.
