Voltage Drop for Fire Alarm Systems | Fire Alarms Online
The suggested maximum allowable voltage drop on a fire alarm circuit is 10% or the voltage drop included in the fire alarm control panel installation guide, whichever is less. "Lump Sum Method" Step #1) Take the total current of the circuit. You can achieve this figure by adding up the current draw of each device on the circuit.
Battery Monitor[512], Alarm
I had 2x US3000 for half a year without voltage alarms and 100% SOC. SVS was on, not sure why. I added a third US3000 and now I had voltage alarms for a week, always at low charging currents. SOC reaches 97%. SVS is off now. Battery monitor is Pylontech. When I had SVS on, behavior was the same. It seems SVS off causes 52.0 V instead of 52.4 V.
