The Macurco TX-6-ND is a low voltage, dual relay Nitrogen Dioxide (NO2) detector, controller and transducer.

The TX-6-ND has selectable 4-20 mA output, buzzer and digital display options. It is an electronic detection system used to measure the concentration of NO2 and provide feedback and automatic exhaust fan control to help reduce NO2 concentrations in parking garages, maintenance facilities or other commercial applications. The TX-6-ND is a low level meter capable of displaying from 0-20 ppm of Nitrogen Dioxide.

Selectable options include:

  • Fan relay actuation: selectable from 0.2 to 5.0 ppm NO2
  • Output: Fan relay, Alarm relay and 4-20mA current loop
  • Controls: Digital display (0-20 ppm), buzzer, fan delay, fan minimum runtime

Installation

  • Mounts on a standard 4” x 4” electrical box
  • 5 A SPDT fan relay controls valves, louvers or exhaust fans
  • 0.5 A N.O. or N.C alarm relay connects to warning devices or control panels
  • 4-20mA current loop - compatible with the Macurco DVP-120 Control Panel
  • Factory calibrated

Other Features

  • Supervised system design: detector problem will cause the fan & alarm relay to activate
  • Optional calibration kit allows the TX-6-ND to be field tested and calibrated
  • ETL Listed to UL 61010-1

Location

A TX-6-ND is normally mounted at breathing level, about 5 feet (1.5 meters) above the floor on a wall or column in a central area where air movement is generally good. The unit, on average, can cover about 5,000 sq. ft. (465 sq. meters). The coverage depends on air movement within the room or facility. Extra detectors may be needed near any areas where people work or where the air is stagnant. The TX-6-ND mounts on a 4x4 electrical box supplied by the contractor. Do not install the TX-6-ND inside another box unless it has good air flow through it. Do NOT mount the TX-6-ND where the normal ambient temperature is below below 0°F or exceeds 125°F (below -18°C or above 52°C).
