Description

The System Sensor 2151 is a low-profile, conventional photoelectric smoke sensor designed to meet the strict performance criteria of special applications and commercial life safety systems. Utilizing an advanced optical sensing chamber, the 2151 detects visible smoke particles produced by a wide range of combustion sources while maintaining high stability against ambient air currents, stray light, and insect intrusion.

Engineered with a low-profile white housing, the unit integrates smoothly into aesthetic architectural spaces. The 2151 communicates through a variety of plug-in mounting bases (2-wire or 4-wire configurations), offering flexible compatibility with commercial fire alarm control panels. It features dual status LEDs for 360-degree visual tracking, field-replaceable optical sensing chambers for rapid servicing, and built-in remote LED annunciator capability.

Features

  • Versatile Plug-In Base Design: Compatible with a wide variety of 2-wire and 4-wire bases (such as B110LP, B112LP, B114LP) across different voltages.
  • High Air-Velocity Performance: Rated for air velocities up to 3,000 FPM, making it suited for open area protection and special HVAC duct application uses.
  • Advanced Optical Sensing Chamber: Highly responsive to smoldering fires while incorporating custom IC signal processing to reduce false alarms.
  • 360-Degree LED Visibility: Features twin status LEDs that flash during normal standby operation and latch solid red when activated.
  • Field Testing Options: Supports direct magnet testing and field-sensitivity metering via the MOD400R test module to meet NFPA 72 compliance.
