Battery capacity
You must do the battery capacity calculations separately for each part of the system that has a separate power
supply and standby battery. See
Battery calculation worksheet
on page 16 for a sample worksheet. To
determine the correct battery capacities for you system, do the following:
1. Determine the exact configuration of your system.
2. Use a separate battery calculation worksheet for each part of your system that has a separate power
supply and standby battery:
a. In the top row of the worksheet, list the primary component (control panel or expansion module)
that is powered by the standby battery. Expansion modules include zone expander modules, relay
modules, keypads, and card readers.
b. Add rows for all expansion modules or other devices that are powered by the primary component
on that worksheet.
c. Add rows for any type of notification appliance that is connected to corresponding circuits on the
primary component on that worksheet. Include rows for auxiliary power circuits that have attached
devices.
3. Starting with the first worksheet, repeat the following procedures for each worksheet.
a. In the row for the primary component, enter the current listed for that device in the
Total standby
current
column. For the control panel worksheet, this value is 200mA.
b. In rows for any expansion modules, enter the operating current for the module in the
Standby
current
column. Multiply the value in the
Standby current
column by the attached quantity of
modules of that type. Enter the result in the same row in the
Total standby current
column. If any
row contains AL-1191 or AL-1193 card readers, enter 80 mA in the
Active current
column for that
row. Multiply any value in the
Active current
column by the number of attached card readers and
enter the result in the same row in the
Total active current
column.
c. In each notification appliance row, enter the alarm current drawn by a single device in the
Alarm
current per device
column. Multiply the value in the
Alarm current per device
column by the
number of devices used on that circuit for each row. Enter the result in the same row in the
Total
alarm current
column.
d. In rows listing devices that are attached to auxiliary power terminals of the primary component,
enter the operating current for each device in the
Standby current per device
column. Multiply the
value in the
Standby current per device
column by the number of devices attached to that auxiliary
power circuit and enter the result in the same row in the
Total standby current
column.
e. At the bottom of each worksheet, total the values in the
Total standby current
column, the
Total
alarm current
column, and the
Total active current
column.
