The core of building electrical fire early warning lies in the collaborative design of an intelligent sensor network and linkage control. In response to the issues of delayed response and high false alarm rates in traditional monitoring methods

this paper establishes a distributed monitoring system based on the integration of multiple types of sensors

covering parameters such as current

voltage

temperature

smoke

and gas. The system utilizes a high-reliability and low-power transmission method to ensure data stability. At the same time

by combining real-time monitoring with dynamic threshold adjustments

it enhances the ability to detect fires at an early stage. Additionally

a graded response mechanism is designed for fire alerts

which links intelligent power disconnection

fire protection systems

and emergency evacuation devices. This approach achieves precise fire precursor warnings and efficient handling

reduces fire damage

and enhances the electrical safety of buildings.
