Pan Ocean Three Rivers GBQTL2100 fire mainframe displays the fault as - ""Sound and light alarm type does not match"" How should I deal with it?

Please check whether the far-sound indicator on the panel is lit; whether there is a fault message of this alarm or sound-optical alarm on the mainframe;

Whether there is a 24V power supply at the site of the alarm or sound-optical alarm;

Check whether the type of the control module of the alarm has been set as a far-sound or sound-optical alarm;

Please also check whether there is an output of an alarm/ sound-optical alarm in the linkage setup.

The controller and the service provider are the upper machine, and the controlled and the served are the lower machine, which can also be understood as the relationship between the master and the slave, but the upper machine and the lower machine are convertible.

Working principle:

1, how the two machines communicate, generally depends on the lower machine, TCP/IP is generally supported, but the lower machine generally has a more reliable unique communication protocol, buy the lower machine, will come with a large number of manuals on CD-ROM, tell you how to use the unique protocols to communicate.

2, usually the upper and lower computer communication can use different communication protocols, there can be RS232 serial communication or RS485 serial communication. When the computer and PLC communication, not only can use the traditional D form of serial communication, but also can be used more suitable for industrial control of two-wire PROFIBUS-DP communication.
