Information About FSP-851

The FSP-851 is an intelligent photoelectric smoke detector developed for Notifier addressable fire alarm systems, featuring an optical sensing chamber designed to detect smoke from a wide range of combustion sources. The detector supports programmable sensitivity set through panel software, with ongoing monitoring that reports chamber conditions to the control panel. Point ID capability, configured using rotary decimal switches, enables accurate address assignment and simplifies identification during maintenance or contamination events. The device installs into the B501 base and is suitable for applications requiring advanced communication, selective maintenance, and continuous sensitivity supervision.

Key Features

  • Intelligent photoelectric detection: Provides accurate sensing using an engineered optical chamber.
  • Programmable sensitivity: Adjustable thresholds managed through control panel software.
  • Continuous chamber monitoring: Sends real-time condition status to the fire alarm panel.
  • Integral communication: Enables robust addressable system interaction.
  • Point ID addressing: Rotary switches allow precise detector location identification.
  • Plug-in design: Installs quickly into the B501 base.
  • Wide operating voltage range: Functions within 15–32 VDC systems.
  • Upgradeable compatibility: Replaced in newer applications by the FSP-951.

The FSP-851 delivers the reliability and precision required for advanced addressable fire detection.
