LCD Chinese character display, featuring two sets of isolated RS485 communication interfaces. RS485-1 is used to connect multiple high-altitude water cannons or large space detectors, enabling.
Equipment inspection and various manual operations; RS485-2 can enable networking between the DK694 host and multiple manual operation panels.
It is equipped with a hardware clock that can record corresponding events that occur at any time, such as fire alarms, malfunctions, and other event information.
It has both manual and automatic functions. In manual mode, the water pump and valve power supply can only be activated after confirming the fire alarm and startup information of the machine. In automatic mode.
