💢 12V Saina fire alarm panel backup battery

🔸 Input voltage of 220 volts AC city electricity

🔺 The intensity of the output current is 4.5 ampere hours

🔸 In fire alarm systems, the output voltage should be 24 V DC, so two 12 V batteries should be used

🔹 As long as the city electricity is connected, the panel is responsible for keeping the batteries charged at the appropriate voltage
