Description

The Nortech NGA-402 is a high-performance analogue addressable heat detector designed for use with the Nortech NGA series control panels. It is specifically engineered for areas characterized by high levels of dust, steam, or smoke under normal conditions?such as kitchens, boiler rooms, or laundry facilities?where photoelectric detectors would be prone to false alarms.

Features

  • Dual Sensing Technology: Monitors both the speed of temperature increase and the absolute temperature, ensuring rapid response to various fire types.
  • Precise Addressability: Allows the fire panel to identify the exact device in alarm, facilitating a faster response from building staff or emergency services.
  • High False Alarm Immunity: Ideal for use in “dirty” environments containing steam, dust, or fumes that would trigger standard smoke detectors.
  • Digital Communication Protocol: Provides high-speed, reliable data transmission to the control panel with high resistance to electrical interference.
  • 360 Degree Visibility: Equipped with dual bicolored LEDs to ensure the alarm status can be confirmed from any viewing angle.
  • Microprocessor Controlled: The internal electronics provide intelligent signal processing to ensure stability and accurate reporting of heat levels.
  • Easy Installation: Uses a standard Nortech addressable base with a simple twist-lock action, making commissioning and maintenance straightforward.
  • Aesthetic Integration: Features a low-profile, sleek design that minimizes visual impact on the ceiling.
