Macurco MA-GD6 Combustible Gas Detector Controller and Transducer


Our Price : $402.47

Product Code: MA-GD6


The GD-6 is a versatile, easy-to-use device that allows you to select between methane, propane or hydrogen gas detection. It provides low-level detection of combustible gas in an easy-to-maintain monitor that is factory calibrated for simple installation.

This low voltage detector provides automatic feedback and fan control that can help reduce combustible gas concentrations in parking garages, maintenance facilities, and other locations that require combustible gas detection.

Selectable options include:
Measurement: Methane (NG), Propane (LP) or Hydrogen (H2)
Output: Fan relay, alarm relay and 4-20 mA current loop
Controls: Digital display (0-50% LEL), buzzer, fan delay, fan minimum run time

Display, Control & Calibration:
Selectable (on/off) digital display, buzzer, fan delay (minutes), fan minimum run time
Selectable fan and alarm relay activation
Factory calibrated. Can also be field calibrated using 10% LEL Methane, 10% LEL Propane or 10% LEL Hydrogen gas, regulator and calibration hood
One screw allows access for calibration

Mounts on a standard 4" x 4" electrical box, no cover needed
5 A SPDT fan relay controls starters of exhaust fans
0.5 A N.O. or N.C. alarm relay connects to warning devices or control panels
4-20 mA current loop
Optional calibration kits allow the GD-6 to be tested and field calibrated using Methane, Propane or Hydrogen gas

  • Measures Methane (NG), Propane (LP) or Hydrogen (H2)
  • Low level meter capable of displaying from 0-50% LEL EX
  • Supervised system design: internal detector problem will cause the fan & alarm relay to activate
  • ETL Listed to UL 61010-1
  • GD-6 can be used with 12VDC or 24VDC N.O. (fire) panels.
  • Alarm panel provides battery backed up power to GD-6.
  • GD-6 dry contact fan relay can use panel power or fan power. Check ratings on panel and fan.
  • Match fan relay contacts to fan size, and coil voltage to power source.
  • Alarm control panels are available with many features and can control other devices such as smoke detectors, fire detectors and burglar alarms.
