951 Series Photoelectric Smoke Detectors

FSP-951, FSP-951-IV, FSP-951T, FSP-951T-IV, FSP-951R, FSP-951R-IV

NOTIFIER 951 Series Intelligent Plug-In Smoke Detectors with integral communication provides features that surpass conventional devices

Our photoelectric detector’s unique optical sensing chamber is engineered to sense smoke produced by a wide range of combustion sources. Intelligent (addressable) detectors include point ID capability that enable each detector address to be set with rotary address switches to provide exact detector locations. The sensitivity can be programmed using the control panel software to suit the environment. In addition, detector sensitivity is continually monitored and reported to the panel.
