Fire Alarm Thermistor

Thermistors for Fast Temperature Detection in Fire Alarms

In fire alarms, rapid detection of abnormal temperature increases and consistent sensing performance are essential for reliable fire detection.

Shibaura Electronics’ thermistor sensors offer excellent responsiveness and accurately detect temperature changes, contributing to fire detection systems and safety control functions.

We provide flexible sensor designs and assembly processing tailored to specific operating environments, installation requirements, and performance specifications.

Shibaura Electronics’ thermistor sensors offer the following features ideally suited for fire alarm applications:

  • Highly responsive thermistor elements quickly detect rapid increases in ambient temperature, supporting the early detection of abnormal heat generation and fire-related events.
  • Stable resistance-temperature characteristics enable reliable discrimination between normal temperature fluctuations and abnormal temperature rises, while maintaining sensing performance over extended standby periods.
  • Sensor specifications can be customized to fit limited installation spaces within sensing chambers and device enclosures, incorporating miniature thermistor elements, lead wires, and mounting structures optimized for the application.
