4 DESIGN: CALCULATIONS AND TESTS
4.1 SIZING OF THE POWER SUPPLIES AND THE BATTERIES
All the tests and calculations to be carried out in order to ensure that the power supplies and batteries to be installed are
capable of powering all the devices for the period of time specified by standard EN50131 are illustrated below.
4.1.1 Battery sizing
The system must be sized so as to guarantee, in case of a blackout, the minimum time of autonomy required by standard
EN50131, depending on the selected grade of security. Therefore, in order to guarantee minimum duration of the battery,
the system powered directly by the control panel must comply with the following requirements.

) the time of autonomy can be halved to 30 hours if the system is remotely assisted with a guarantee of intervention in
case of blackout.
