IoT-Linked Compact Fire Extinguisher
Wireless Automatic Fire Suppression System
An IoT-based fire response solution optimized for fire-vulnerable compact spaces

Overview
Smart IoT-based
Temperature-sensing
wireless-monitored compact space auto-suppression solution
An IoT-based fire response solution optimized for fire-vulnerable compact spaces. It detects temperature changes inside compact spaces in real time and immediately sends alerts to the control room, and when the activation temperature is reached it automatically discharges extinguishing agent to control the fire at an early stage. An integrated smart response system covering detection, alerting and suppression secures both equipment stability and operational reliability.
Installed inside enclosed compact spaces with high fire risk, such as electrical facilities and data centers
Sends a first alert to the control room via wireless communication when temperature rises above 60℃, supporting early response
Automatically discharges extinguishing gas and raises an alarm when the internal temperature reaches 68℃
Applies a staged temperature-based alert and automatic suppression linkage system
