230VAC terminal and ground terminal for chassis protection.
BAT, GND:
24VDC battery input terminal.
LOOP IN, LOOP OUT:
Class A loop, able to connect up to 128 addressable devices. The
loop device protected by isolators will not lose when short or broken circuit occurs, and the

24VDC auxiliary power output, the maximum output current is 500mA.
FAULT OUTPUT:
Voltage-free contact output, COM is the common terminal, NC is normally
closed contact, NO is normally open contact. When there is fault signal, normally open
contact is closed; when the fault is removed, it opens. It can be disabled, and does not output
when fire alarm occurs in disabled state.
ALARM OUTPUT:
Passive contact output. COM is the common terminal, NC is normally
closed contact, NO is normally open contact. When there is fire or supervisory signal, the
normally open contact is closed. It can be disabled, and does not output when fire alarm or
supervisory condition occurs in disabled state.
EARTH:
Terminal for checking ground fault, which is enabled by shorting it with a cable.
