• The formula for defining the minimum battery capacity for achieving “n” hours of self-sufficiency is:
(Consumption when idle x no. hours x 1.25) + (Consumption during alarm x minutes of alarm x 0.02)
1000
Example of how to calculate minimum battery
capacity. The following data is required:
• Total control unit and means of alarm consumption
when idle (all components that are not self-
powered) in mA* in the example:190mA
• Length of self-sufficiency required in hours: in the
example 24h
• Total consumption during alarm in mA: in the
example 1240 mA*
• Duration of an alarm cycle in minutes: in the
example 5 minutes
* From technical data sheets or by supplying the
system without 220V power mains network and
inserting a current measurement tester between the battery and the control unit
(190 mA x 24 hours x 1.25) + (1,240mA x 5 minutes x 0.02)
5,700 + 124
=
=
5.82 Ah

• This means that to ensure 24h autonomy the battery to use must have a rated capacity on its label equal to or
greater than 6 Ah.

11.1 CALCULATING SYSTEM AUTONOMY
• The purpose of this paragraph is to offer a method for calculating the consumption of a system and as a
consequence pinpoint actual self-sufficiency during a mains 230V~power failure.
• First of all the consumption data during service must be collected for all elements in the alarm system. There
follow several examples of indicative consumption data taken from the product instructions or obtained by
measuring with a multimeter (see chart below).
WHEN IDLE:
1 Control unit ....................................................................................................................... 70 mA
1 Connector ......................................................................................................................... 15 mA
2 infrared sensors ................................................................................................................ 20 mA
1 dual sensor ....................................................................................................................... 32 mA
1 telephone dialing device ................................................................................................... 30 mA
1 outdoor self-powerd siren ................................................................................................. 22 mA
1 indoor siren ....................................................................................................................... 0 mA
Total consumption when idle: ............................................................................................... 190 mA
DURING ALARM:
Consumption when idle: ...................................................................................................... 190 mA
1 telephone dialing device ................................................................................................... 50 mA
1 indoor siren ....................................................................................................................... 1000 mA
Total consumption during an alarm ...................................................................................... 1240 mA
