NOTIFIER FST-951 Fire Alarm Thermal Sensor - This advanced addressable thermal detector provides precise, reliable fire detection for mission-critical commercial safety systems. - 135°F fixed temperature threshold ensures rapid and accurate activation during fire events. - Rate-of-rise detection capability triggers alarms when temperature changes exceed 15°F per minute. - Integrated LED status indicators offer 360-degree visibility for quick on-site diagnostics. - Low-profile aesthetic design maintains a professional, unobtrusive look in any ceiling installation. - Compatible with Notifier ONYX series panels, integrating seamlessly into existing fire alarm control architectures.

Building on the legacy of the FST-851 series, the FST-951 utilizes sophisticated digital communication protocols to reduce false alarms while increasing sensitivity to genuine heat signatures. This modern model offers superior signal processing and enhanced noise immunity compared to older analog sensors, ensuring your facility remains protected by the latest in life-safety technology.

Innovative Thermal Sensing Technology

The FST-951 employs a highly responsive thermistor to monitor ambient conditions continuously, allowing the system to distinguish between rapid temperature spikes and routine fluctuations. Its intelligent design supports drift compensation, which automatically adjusts sensitivity as the sensor ages, maintaining peak performance throughout the product's lifespan. By choosing this thermal sensor, facility managers gain a robust, industry-standard solution for environments where smoke detection may be impractical or prone to nuisance alarms.
