6 Series

The 6 Series is the low voltage line of sensors offered by Macurco. Each sensor in this series is designed to monitor a specific type of gas, provide feedback, and control a response. Environments that can benefit from the 6 Series include boiler rooms, parking garages, warehouses, kitchens, and cold rooms.
Gasses monitored by this series include:

  • CO
  • CO2
  • O2
  • NO2
  • Ammonia
  • Hydrogen sulfide
  • Combustible gasses
  • Refrigerant gasses

These sensors can work as a stand-alone detector or can work in conjunction with other Macurco products.

CO2 is heavier than air. Mounting height will be dependent on the application. For applications with CO2 tanks mount about one foot above the floor. For Indoor Air Quality mount detector at breathing level, ~ 5 feet (1.5 meters) above the floor. Mount on a wall or column in a central area where the air gets refreshed on a regular basis. The unit typically covers up to about 5,000 sq.ft. (465square meters). Additional detectors may be needed near any areas where people work or where the air is stagnant. The CD-6H mounts on a 4x4 electrical boxsupplied by the contractor. Do not install the CD-6H inside another box unless it has good air flow through it. Do NOT mount the CD-6H where the normal temperature is below 32°F or exceeds 122°F (below 0°C or above 50°C).
