In a potential fire, the initial temperature rise is often the earliest warning signal. The key component that captures this signal is the EXSENSE miniature insulated lead NTC thermistor hidden inside the fire alarm. Due to its negative temperature coefficient feature, where its resistance value decreases as the temperature rises, the NTC thermistor can quickly respond to abnormal environmental temperature changes, alerting on-site personnel to evacuate. This gains valuable time for emergency response in the early stages of a fire and effectively reduces losses of life and property.

In different design schemes, the installation position of NTC thermistors in fire alarms may vary slightly, but their core function remains to assist the alarm in precise temperature monitoring. In most schemes, EXSENSE thermistor is typically mounted on the PCB of the fire alarm. When the temperature rises and reaches the preset safety warning threshold, the significant change in resistance value is converted by the microcontroller into a trigger signal through algorithms to activate the audible and visual alarm system. Fire alarm can also be integrated with IoT platforms to simultaneously alert the fire department. This helps control the fire while transitioning from passive warning to active intervention. As the first line of defense in monitoring abnormal temperatures, the outstanding characteristics of EXSENSE miniature insulated lead NTC thermistor is indispensable:

1. High accuracy: It helps fire alarm accurately distinguish between normal temperature fluctuations and early-stage abnormal temperature rises. For instance, indoor temperatures may rise in a short period of time in summer, which is normal. The high accuracy of EXSENSE thermistor can prevent false alarms, reducing the risk of misreporting. During the early stages of a fire, its high accuracy can capture minor temperature anomalies promptly, ensuring accurate alarm threshold settings and preventing missed alarms.

2. High Sensitivity: The small size of the temperature sensing head of miniature insulated lead NTC thermistor allows it to respond quickly to abnormal temperatures, enabling the fire alarm to issue an immediate warning in the early stages of a fire. This provides more buffer time for subsequent evacuation and firefighting operations.

In summary, fire alarm equipped with EXSENSE miniature insulated lead NTC thermistor effectively monitors environmental temperature changes and send timely alerts, significantly reducing fire risk. Fire alarm with EXSENSE miniature insulated lead NTC thermistor, combined with IoT technology, advances fire warning from single-point alarms to an intelligent, coordinated defense system. This builds a solid temperature monitoring line of defense for public safety, industrial production, and home protection, contributing to the overall enhancement of fire prevention and control capabilities of people.
