Traditional fire alarm wire: Traditional fire alarm wire is the most basic type, usually composed of metal wires and insulation layers. When a fire occurs, the wire will transmit a signal to the central control room or fire alarm controller to trigger the alarm. The advantages of this kind of fire alarm line are low cost and easy installation, but the disadvantage is that it can only provide basic fire alarm functions.
Fiber optic fire alarm line: Fiber optic fire alarm line is a system that transmits fire alarm signals through optical fiber. Optical fiber has high robustness and anti-interference ability, can transmit fire alarm signals accurately and quickly, and is not susceptible to external electromagnetic interference.
