1.If fire-fighting equipment output signal is active power, the signal source need to change over the line connection, for example to connect through a relay to change the
line connection,and connect the relay NO point to 401,402, when NO contact point closed ATS transfer to OFF position. When the fire linkage function is active, the ATS
will stop working,if want the ATS to working again, must first clear up the fire-fighting signal and then the ATS will recovery normal operation. If it is intelligent type , need
switching Manual/Auto button one time.
2. When the backup power is Auto start generator, when normal power is good 501 and 502 open; When Normal power is fault, 501 and 502 closed
3. RS485 Communication interface manual please refer to communication protocol.
