If you want to get the answer about the above question quickly, you can watch the below video at first !
Then, let you can read the article about how does a fire control panel system work.
firstly, we should know what does a fire control panel system do ?
A fire control panel system also called fire alarm control panel (FACP), fire alarm control unit (FACU), or simply fire control panel system is the controlling component of a fire alarm system. … The panel may also supply electrical energy to operate any associated initiating device, notification appliance, control, transmitter, or relay.
Next, we should know about how is a fire control panel system wired?
The fire control panel system is wired to a minimum of two sounder circuits which could contain fire alarm bells, electronic sounders （siren alarm，strobe alarm）or other audible devices. It is these devices which sound the alarm when triggered. … The detection circuit is wired as a loop and up to 25 devices may be connected to each loop. Such as our SR-P01 series （please click fire control panel system to get more info）
Okay, now let’s take a brief look at how does a conventional fire control panel system work ？
Conventional panels represent a building as a series of regions known as detection zones. When a smoke detector or pull switch in a zone activates, the electrical current to the fire control panel system changes, and the control panel indicates that a device somewhere in that zone has been activated
The words is relatively simple, it may be difficult to explain, I suggest you watch the above video directly. thank you ！
