Description

The Nortech NG-401 is a high-performance conventional photoelectric smoke detector engineered for the rapid detection of slow-smoldering fires in 24V fire alarm systems. Utilizing an advanced optical sensing chamber, it effectively monitors for visible smoke particles while minimizing false alarms caused by transient environmental factors. The unit features a low-profile aesthetic, a 360? alarm LED for clear visibility, and a specialized insect-resistant screen to protect the internal circuitry

Features

  • Smoldering Fire Optimization: Tailored specifically to recognize light-scattering visible smoke particles early, making it highly responsive to slow, creeping structural fires.
  • Nuisance Alarm Protection: Utilizes an integrated internal insect filter and optimized optical labyrinth to block airborne bugs and minimize interference from minor moisture vapors.
  • Omnidirectional Alarm Visibility: Built with twin high-intensity red LEDs set into the low-profile frame, ensuring immediate 360-degree status indication from any point below.
  • SMD Circuit Architecture: Engineered with high-quality surface-mount circuitry to guarantee stable digital signal processing and long-term resistance against localized field vibrations.
  • Twist-Lock Alignment Base: Designed for quick mechanical assembly into its matching common base configuration, simplifying routine testing, maintenance, and head cleanings.
  • Rugged Enclosure Build: Molded out of durable, non-fading structural ABS polymer to withstand light physical impacts and blend smoothly into modern industrial ceiling grids.
