Is the fire alarm and linkage controller the main fire engine?
The concept of fire engine is larger, and the main engine of fire alarm system and fire extinguishing system can be called fire engine.
For example, the controller is equivalent to the human hand, feet, is used for practical work; and fire engines are similar to the human brain, is used to judge and send instructions.
A larger fire control system, there will be more than a general controller, but the fire engine is generally only one. Of course, the controller and fire engine are also likely to be integrated into a very small fire system.
NoThe controller is an actual control, alarm, probe, or device. The fire master is used to provide logical handling and control instructions for the controller.
In the system, the controller that controls all alarm and linkage devices is the host. Several controllers can also form a network in which there is only one host. The other controller is an extension.
