Battery capacity at end of battery life = ( Iq x 24 ) + Fc( Ia x 0.5 )
= ( 769ma x 24 ) + 2( 1049ma x 0.5 )
= 1 1050ma
Note:
☞
1,000ma = 1 Amp
= 19.506Ah
New battery capacity requirement = 19.5 x 1.25
= 24.375 Ah
Rounded up to nearest available 25 Ah
PRIMARY POWER SOURCE CALCULATIONS
Battery Charger Current
Requirement: Battery is charged for 24 hrs. to provide 5Iq + 0.5Ia
=
( 5x Iq ) + Fc( 0.5 x Ia )
= ( 5 x 769 ) + 2( 0.5 x 1049 )
= 3845 + 1050
Ah Requirement = 4.895Ah
Battery Charging Current Required = 4.895
24 x e
e is the battery efficiency, 0.8 = 0.26A ( rounded )
Power Supply Requirement
Select the greater of 1 or 2
1. Ia + non- battery backed ancillary alarm loads
2. Iq + non – battery backed quiescent loads
If the power supply is used as the charger the current rating of the supply shall be
[(
1 or 2 ) + battery charger current ].
