Notifier Multi Detector FSP-951T

  • Combination Sensing:
    • It’s a multi-sensor detector, meaning it combines both photoelectric smoke detection and thermal (heat) detection. This allows it to respond to a wider range of fire types.   
    • Photoelectric sensing is effective for detecting smoldering fires, while the thermal sensor reacts to rapid temperature increases.
  • Addressable-Analog Communication:
    • It’s an addressable device, which means each detector has a unique address. This allows the fire alarm control panel to pinpoint the exact location of a fire.   
    • It uses analog communication to transmit information about smoke density and temperature to the control panel.   
  • Design and Aesthetics:
    • It features a sleek, low-profile design, intended to be aesthetically pleasing.   
    • It’s typically available in white.
  • Key Features:
    • Rotary address switches for easy addressing.   
    • Dual LEDs for 360° visibility.   
    • Low standby current.   
    • It is designed to meet UL268 7th Edition standards.   
  • Applications:
    • Primarily used in commercial and industrial fire alarm systems.
