851 Series Photoelectric Smoke Detectors

FSP-851, FSP-851T, FSP-851R
Distributor Locator

The FSP-851 is a Photoelectric detector for use with ONYX Series panels.

The FSP-851T is a Photoelectric detector with thermal detection for use with ONYX Series panels.

The FSP-851R is a Photoelectric detector suitable for use with DNR(W) duct smoke detectors and ONYX Series panels.

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.
