Check that the load for each output is in the allowed limits
Refer to devices’ producer data sheets to know necessary current in standby and working mode. Check
that current is less than 1,55 Ampere.
Current absorption for standby or alarm can’t be more than power supply capacity in any case. If
calculated current is more than 1.55 Ampere (supplied by power supply unit) excess current is retrieved
by batteries.
Sum of all currents obtained must be multiplied per 1.25 to take into consideration batteries’
manufacturing tolerances.
