NOTIFIER 851 Series intelligent plug-in smoke detectors with integral communication provide features that surpass conventional detectors. Detector sensitivity can be programmed in the control panel software. Sensitivity is continuously monitored and reported to the panel. Point ID capability allows each detector’s address to be set with decade address switches, providing exact detector locations for selective maintenance when chamber contamination reaches an unacceptable level.

The FSP-851 photoelectric detector’s unique optical sensing chamber is engineered to sense smoke produced by a wide range of combustion sources. Dual electronic thermistors add 135F (57C) fixed-temperature thermal sensing on the FSP-851T. Also avalible the FSI-851 Ionization detector with a unique single source, duel chamber design to resopnd quickly and dependably to a broad range of fires.
