The Notifier FST-951H is an intelligent addressable high temperature 190F thermal detector for Notifier SLC loops using FlashScan protocol. It uses rotary decimal switches for device addressing. It replaces the older FST-851H Series and uses an enhanced thermistor sensing circuit for 190F high temperature operation.

Key Specifications:
