Section 3 - Installing the Control
3-3
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).
Use a 2-line alpha display, 6139/6160 (gray or red)
(check with local AHJ for approval of keypad color).
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 keypad(s) to terminals 11, 12, 13,
and 14 on the control board, see Figure 3-4.
NOTE:
If using only one keypad, it may be
connected to either Keypad Port 1 or 2, and
must be mounted on, or within three feet of
the cabinet. 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).

Addressing the Keypads
The keypads will not operate until they are
physically addressed and enabled in the
system's
Device Programming
in the
#93 Menu
Mode
.
Set each keypad for an individual address (00-30)
according to the keypad's instructions. Set an alpha
keypad for address 00 and other keypads for higher
addresses (00 and 01 are enabled in the system's
default program). Any keypads set for address 02 and
above will appear blank until they are enabled in the
system's program. Each keypad must be set for a
different address.
Do not set any keypads to address 31
(nonaddressable mode). They will interfere
with other keypads (as well as other devices)
connected to the keypad terminals.
If an “OC” or “OPEN CIRCUIT” message is
present on a keypad, data from the control is
not reaching the keypad. Please check your
wiring.
Supplementary Power Supply for Additional Keypads
When the control’s auxiliary power load for all devices
exceeds 1A, you can power additional keypads from a
regulated 12VDC power supply (e.g., ADEMCO
AD12612 (1.2A)). Use a UL Listed, battery-backed
supply for UL installations.
Connect the additional keypads as shown in Figure 3-5,
using the keypad wire colors shown. Be sure to observe
the current ratings for the power supply used.
Make connections directly to the screw
terminals as shown in
Figure 3-5
. Make no
connection to the keypad blue wire (if
present).
Be sure to connect the negative (–) terminal
on the power supply unit to terminal 7 (
–
) on
the control.
