Sierra S5832SG Backup Battery, AH Requirements for Backup, Sierra Accessory Loading, AC Power

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.

Sierra Accessory Loading

C & K Model 1265 or 1270

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:

Product Current Consumption		Max. Standby	Max. Active
S5832SG Control Panel		125 mA	125 mA
S5010	Alpha Keypad	30 mA	50 mA
S5020	Icon Keypad	30 mA	50 mA
S5030 LED Keypad		30 mA	50 mA
S5050	REMM (up to 2)	100 mA (each)	100 mA
(Relay/Event Memory Module)
S5058	ZEM (up to 3)	40 mA (each)	40 mA**
(Zone Expansion Module)
S5070 Single-line Digital		35 mA	60 mA
	Communicator
S5070-2 Dual-line Digital		35 mA	70 mA
	Communicator
SN915-BUS RF Receiver		125 mA	170 mA
	** ZEM VOUT Terminals can supply up to 300 mA (max.)
Table 1 - Standby Battery Loading

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.

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.
