9.3 Exhaust System
When the concentration of combustible gas is detected to reach 10% LEL, the combustible
gas detector in the BESS sends a signal to the station-level alarm host for fire warning
through the BSC external terminal, while the signal is transmitted to the EMS to shut down
the BESS and turn on the exhaust system (start the air intake equipment and exhaust
equipment).
