4. In Table 4, enter the total calculated subtotals of
all listed outputs from Tables 1 through 3, then
add to get the combined current.

Determining the Size of the Standby Battery
The cabinet supplied with the VISTA-128B PLUS panel
can house batteries of up to 12V, 14AH (two 12V, 7AH
batteries wired in parallel). The VISTA-ULKT kit
provides a cabinet that can house batteries of up to
12V, 17.2AH and that may be used with this panel. The
total standby current drawn from the auxiliary power
and polling loop outputs combined must be limited to
270mA when 14AH batteries are used; and to 390mA
when 17.2AH batteries are used.
DO NOT use Gates batteries (sealed lead-acid
type). These batteries require a different
charging voltage than is supplied by the panel.
UL
Household Fire or Combination
Household/Fire/Burglary installations require
the use of a backup battery that is capable of
providing 24 hours of standby time followed by
4 minutes of alarm time. UL1023 Household
Burglary-only installations require the use of a
backup battery that is capable of providing 4
hours of standby time followed by 4 minutes of
alarm time.
Use Table 5 to determine the required backup battery
capacity and use Table 6 to determine the battery
model number. A dual battery harness is supplied
that allows two batteries to be wired in parallel for
increased capacity.
5. Using the total calculated from Table 4, calculate
the battery capacity required for the installation.
