Notifier FPTI-951 Multi-Criteria Detector

The Notifier FPTI-951 is a commercial addressable multi criteria detector designed for compatible Notifier intelligent fire alarm systems. It combines smoke, heat, and infrared (PTIR) sensing technologies into a single detector to provide enhanced fire detection while improving immunity to nuisance alarms caused by dust, steam, and other non-fire particulates.

Using sophisticated multi-sensor algorithms, the detector analyzes multiple fire signatures simultaneously, allowing faster and more reliable detection of developing fires than traditional single-sensor detectors. Its low-profile plug-in design, programmable sensitivity, and continuous panel supervision simplify installation and long-term maintenance. This product is intended exclusively for commercial fire alarm installations.

Product Functions

• Multi-criteria fire detection
• Smoke detection
• Heat detection
• Infrared flame signature analysis
• Fixed-temperature and rate-of-rise heat sensing
• Continuous detector supervision
• Programmable detector sensitivity
• Automatic maintenance monitoring
• Individual device identification

Electrical & System Information

The FPTI-951 operates on compatible Notifier FlashScan® addressable signaling line circuits (SLC) with an operating voltage range of 15–32 VDC. The detector continuously communicates with the fire alarm control panel, allowing programmable sensitivity, maintenance reporting, alarm verification, and precise device identification.

Rotary decimal switches simplify field addressing, while the detector installs on compatible Notifier intelligent detector bases including standard, relay, isolator, and sounder bases.
