Total 'standby' and 'alarm' current:
7
Divide 'standby' mA and 'alarm' mA by 1000:
8
Select 'standby' time required (24 or 60 Hr.):
9
Standby Amp-Hr. - multiply 7 × 8 = (Amps × Hr.):
10
Select 'alarm' time required (5 min. = .08 Hr.):
11
Alarm Amp-Hr. - multiply 7 × 10 = (Amps × Hr.):
12
Total Amp-Hr = standby Amp-Hr (9) + alarm Amp-Hr. (11):
13
Multiply the total Amp-Hr. by the safety margin:
14
Total battery Amp-Hr required to support the system:
NOTES:
1. Select a battery with an Amp-Hr. rating that is equal to or larger than the calculated minimum Amp-
Hr. battery required. Note: The maximum battery allowed is 12 Ah.
2. For the relay module, add 8 mA as 'Standby' for each relay programmed for 'Trouble' and add 8 mA
as 'alarm' for each relay programmed for 'alarm'.
3. The Class A modules do not add any 'Standby' or 'alarm' current above that calculated for each zone.
4. When the CFP-161 is used as a Polarity reversal transmitter, add the current draw of the remote
receiver input in the 'standby' mode.
5. For panels used in a 'Remote Station' application (60 Hr. standby), the dialer may be
installed but no current may be drawn from the AUX+ output.
