What line is the centralized fire alarm controller connected to the area controller?
Two are all Bay GST200 controller connection, need to connect network card, ordinary twisted pair can.
If it is not the same brand or can not be directly networked, the signal of the general gas fire control panel to be exchanged with the fire alarm controller is provided:Primary alarm monitoring signalTwo alarm monitoring signalPressure switch monitoring signalAlarm action control signalSound light alarm control signalThus, the signal of the main gas disk can be displayed on the fire alarm control panel.
That should see you two controllers can communicate, if it is the same brand products, and have 485 interface network you can, but when programming should pay attention to the logical relationship between the host cross editor, specific to the type of engine and the system design decisions for you.
