Backup Battery
The system employs one or more 6.5 AH (Model 1265) or 7.0
AH (Model 1270) sealed lead-acid storage battery. Connect
the battery to the control panel PCB via the red (+) and black
(-) leads. The battery should be replaced every 3 - 5 years.
When connecting two or more batteries in parallel, use the
Model S5054 Auxiliary Battery Harness. Both batteries must
have the same AH (Ampere-Hour) rating and should have
the same lot number or date code. Figure 4, below, shows
correct method for wiring the batteries in parallel.
NOTE: Up to 2 batteries may be connected in parallel to
obtain the desired standby (backup) time.
Table 1 shows the current requirements for the Sierra
S5832SG control panel and accessories. Additional infor-
mation about Standby Battery requirements and Audible
times may be found in Table 2 - AH Requirements, at the top
of the next column.

AH Requirements for Backup
Table 2 - AH Requirements
Determining Standby Battery Requirements
To calculate the size (AH rating) of your system's Backup
Battery, enter the Number (Qty) of devices of each type in
the chart above. Multiply the number of devices times the
AH rating for the desired backup period (Qty x AH = Total)
and enter the total in the last column. To determine the
total AH rating of the battery, add all values in the last
column.
Total current from all sensors must be considered when
calculating AH rating. For example:
10 sensors @ 10 mA = 100 mA
4 sensors @ 25 mA = 100 mA
Total current all sensors = 200 mA
AC Power
The Sierra S5832SG receives its power from a 16.5 VAC 40
VA transformer. Connect the transformer to the AC In termi-
nals on TB1 of the PCB (see Figure 1), using 18 AWG (1.02
mm) wire. (Some systems may have the transformer and
mains fuse block installed and pre-wired from the factory.)
Connect the AC transformer to an unswitched receptacle.
Do not share the secondary of the transformer with other
devices.
NOTE: AC input requirements may vary by country. Refer to
the Compliance section for additional wiring information.
