NV-Series Single Gas Multi Point Gas Alarm Sys

The NV-Series system is a Multi-pointSingle gas detection systems that is available in 2, 4, 6, 8, 10 & 12 channel systems.

The NV Series features a wall or panel mounted Indicator/Alarm unit and diffusion or suction type Gas Detector Heads. Depending on the system model chosen, the NV-100 can be used to detect Flammable or Toxic gases at various monitoring ranges.
The Indicator/Alarm unit comes with a direct reading LCD display (with backlight) and supplies power to the gas detector heads. 2-stage voltage and digital outputs are also obtained from the panel to connection to external devices / supervisory systems. The panel has dual-alarm levels with audible and visual alarms.
