Description
I-9333 Interface can connect with C-9404(Ex) Sounder and C-9403(Ex) Sounder Strobe in explosion-proof system. Receiving the start command from fire alarm control panel or the closed contact signal from "S", "G", I-9333 Interface will activate explosion-proof devices in field and transmits the action information to the fire alarm control panel.
When 24VDC power fault or connection fault between the interface and field sounder or sounder strobe occurs, it will send fault signal to fire alarm control panel and illuminate Fault LED.
Built-in safety barrier, it is a relative device to restrict the energy to the explosive environment.
