Notifier FSP-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 rotary, decimal address switches, providing exact detector location 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. FSP-851 series detectors are compatible with Notifier Onyx and CLIP series Fire Alarm Control Panels (FACPs).
