DN-60975:A FST-951 Series ° Intelligent Thermal (Heat) Detectors N OT I F I E R by Honeywell Intelligent Addressable Devices General The NOTIFIER FST-951 Series intelligent thermal detectors are designed for both performance and aesthetics. A new modern, sleek, contemporary design and advanced thermal technologies make the FST-951 Series ideal for both system operation and build- ing design.The point ID address,set using rotary decimal switches, provide specific detector locations. The series includes a 135°F/ 57°C fixed-temperature, rate-of-rise and a 180°F/88°C fixed high- temperature detectors. These thermal detectors provide effective, intelligent property protection in a variety of applications.Detectors are available for both.FlashScan@ and CLIP applications as desig, Hated.
