Power calculations must be completed to determine standby and alarm current loads for the system to ensure
that the system power supply is capable of providing the required quantity of power during normal system
operation and fire alarm conditions. The power requirements cannot exceed the capabilities of the system
power supply. Amp-hour requirements must be calculated as well to determine proper back-up battery size
selection.
The following battery calculation form provides the current draw (standby and alarm) of each compatible
device that can be connected to the system. To calculate the required standby and alarm power, as well as
required back-up battery size for the system, simply list the number of each type of device that will be
connected to the system in the quantity column(s) and perform the required calculations.
