1. Signal transmission: All components in the fire alarm system, such as fire detectors and alarms, need to be powered on for normal operation. The wires on the fire pipe connect these components together and play the role of transmitting signals. 2. Fire detection: The wire on the fire pipe can also detect fire. When a fire breaks out, the fire detector will find an abnormality and send an alarm signal through the wire on the fire pipe to inform the firefighters and relevant units in time. 3. Automatic alarm: The wire on the fire pipe can be connected with the controller of the fire alarm system. Once a fire occurs, the system will automatically send out an alarm signal to protect people's lives and property.
