Description

The Nortech NG-402 is a professional-grade conventional fixed-temperature heat detector specifically designed for environments where smoke, steam, or dust would cause false alarms in optical detectors. It features a precision thermal element that triggers an alarm when the ambient temperature reaches a pre-set 57?C threshold, ensuring a reliable response to rapidly developing fires in areas like kitchens or boiler rooms.

Features

  • Nuisance Alarm Prevention: Tailored specifically for dusty, smoky, or high-humidity environments, remaining completely immune to cooking vapors and industrial dust particles.
  • Omnidirectional Alarm Visibility: Features dual integrated red LEDs structured into the low-profile frame, ensuring status changes are clearly visible from any angle below.
  • Surface Mount Device (SMD) Circuitry: Built up on a premium SMD internal circuit board layout to guarantee reliable digital processing and resistance against environmental vibrations.
  • Simple Twist-Lock Installation: Designed with a clean, low-profile base alignment profile that allows technicians to lock or swap the sensor head quickly without rewiring terminals.
  • Durable Non-Replacement Sensing: Utilizes a rugged, long-life thermal element designed to survive repeated heating tests without drifting from its original 57°C threshold setting.
