Installing The Keypads; Figure 6: Using A Supplementary Power Supply - Honeywell VISTA-128BPT Installation And Setup Manual

VISTA-128BPT/128BPT-SIA/250BPT INSTALLATION AND SETUP GUIDE
Supplementary Power Supply for Additional ECP Devices
When the control's auxiliary power load for all
devices exceeds 750mA, 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
6, 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
6.
• Be sure to connect the negative (–)
terminal on the power supply unit
to terminal 7 (–) on the control.

Installing the Keypads

1. Determine wire gauge by referring to the Wire Run Length/Gauge table above.
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 6.
VOICE KEYPAD NOTES:
• 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.
• The 6160V keypad is not to be used in SIA installations.
• 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).
