Power Supply Set Dimensions External Load Absorption
C.7 External Load Absorption
C.8 Calculation of Total System Absorption
The table below indicates the power supply sets that can be used according to the total alarmed sys-
tem current calculated.
C.9 Calculation of Battery Capacity
According to the European and US standards, the operating time of H-S81-HS control panel with
primary voltage failure is:
• Standby: 24 h
• Alarm: 5 minutes = 0.083 h
