NOTIFIER FST-951 H Thermal Heat Detector – Fixed Temp, ROR, FlashScan, UL Listed

Description

The NOTIFIER® FST-951 Series Intelligent Thermal Detectors are engineered for high-performance fire detection in commercial and industrial environments. As a direct upgrade from the popular FST-851 Series, the FST-951 boasts a modern, low-profile design that complements contemporary building aesthetics while delivering advanced fire protection.

This intelligent series includes models with 135°F (57°C) fixed temperature, rate-of-rise (ROR) detection, and 190°F (88°C) high-temperature sensing options—making them suitable for a broad range of applications, from data centers to mechanical rooms. These detectors are fully compatible with FlashScan® and CLIP communication protocols, allowing seamless integration into NOTIFIER’s intelligent fire alarm control systems.

Each unit connects via a two-wire SLC loop, using a standard base for wiring. The rotary decimal addressing allows easy assignment of unique detector IDs, providing pinpoint accuracy for alarm monitoring and location tracking. Dual LEDs offer 360° visibility for instant identification of status, blinking green when polled and glowing red in alarm.

Key Features:

• Advanced thermal detection with fixed temperature, rate-of-rise, and high-temp options
• Compatible with both FlashScan® and CLIP protocols
• Rotary address switches for exact device location
• Two-wire SLC loop connection with low standby current
• Dual LED indicators for full-circle visibility
• Modern, low-profile design for aesthetic integration
• Built-in tamper resistance and remote test feature
• Designed for surface or electrical box mounting
• UL 521 listed for heat detectors

Whether used in standalone thermal applications or as part of a hybrid detection system, the FST-951 Series offers reliability, style, and intelligent fire protection where it matters most.
