SIGANL OUT: signal output interface, access to the standby amplifier input port.
Note: When using the standby power amplifier, you need adjust its volume to the appropriate
position to ensure the amplifier is 100V output.
System Fault Output—When fault occurs, it will trigger and output a short circuit signal.
System EVAC Output—When fire alarm is triggered, this port will output a short circuit
signal.
Emergency Rest Input—when short-circuit signal is input, the fire alarm emergency
status will be reset.
IMPEDANCE: The button of impedance Calibration, when it is pressed, the system will
calibrate and record the current impedance automatically.
IP REST: The button to reset IP address, when it is press, the system will reset the IP
address of all the slave devices.
LAN: connection supports the TCP/IP protocol network interface
EXTEND: The port of connecting with slave devices.
CAN: The port of connecting with remote microphone interface.
