Calculating autonomy

The battery capacity is chosen as a function of the desired autonomy of the fire alarm system in

the event of a mains failure, for example 24 or 72 hours.

First calculate the total power consumption.

main PCB:

zone in operation:

relay PCB:

integral operating panel:

External operating panel:

current for external devices: e.g. door magnet 75 mA

Example: CM+ with 10 zones, 1 integrated and 1 external operating panel, 1 door magnet = 56

mA+ 3.5 mA+ 3.5 mA+ 75 mA = 148 mA = 0.14 A

Assuming that autonomy has to be for 24 hours: this means that the capacity required is 0.14 A

x 24 hours, which is 3.4 Ah.

The batteries must furthermore be capable of supplying power for 30 minutes in the event of an

alarm:

for example with 10 sirens rated at 40 mA: 10 x 0.040 A x 0.5 hours = 0.2 Ah

A safety factor of at least 1.2 is applied to arrive at the capacity required:

1.2 x ( 3.4 Ah + 0.2 Ah) = 4.3 Ah. A 7 Ah battery set would therefore be a good choice.

7.5 mA +10 mA per activated relay

5 mA

6 mA per activated relay

3.5 mA
