Do you know the theoretical knowledge of conventional control panel ？
Conventional control panels have been around ever since electronics became small enough to make them viable. Conventional control panels are used less frequently in large buildings than in the past, but are not uncommon on smaller projects such as small schools, stores, restaurants, and apartments.
Conventional control panels is designed to operate with conventional automatic fire detectors and manual call points. The conventional control panels has outputs provided for external executive devices.
A conventional control panel employs one or more circuits, connected to initiating devices (usually hardwired smoke detectors, wired heat detectors, duct detectors, manual pull stations, strobe siren alarms, fire alarm bell , and sometimes flame detectors) wired in parallel. These sensors are devised to dramatically decrease the circuit resistance when the environmental influence on any sensor exceeds a predetermined threshold. In a conventional control panel fire alarm system, the information density is limited to the number of such circuits used.
The above is the theoretical knowledge about the conventional control panel ！If you don’t understand these knowledge or you think that there are errors in this article, please point out, thank you ！
