Battery Capacity Calculations - Kidde Gemini II Design, Installation, Operation, And Maintenance Manual

BATTERY CAPACITY CALCULATIONS

A-1 CALCULATION BASIS
The MCP and RHU of the Gemini II System operate on 120 Vac/240 Vac 50/60 Hz power. Each of these units is provided
a battery backup to supply the 24 Vdc operating voltage in case of loss of the AC main power.
The following sections should be used to calculate the exact battery capacity required for a specific system, depending on
its application. First, select the duration for which standby and alarm power is required using Table A-1.
*Note: Central Station and 90 hour standby period may not be used for Canadian applications.
