Macurco GD-xx Operation Manual

1 General Safety Information

1.1 General Description

The Macurco GD-xx is a commercial style Combustible Gas Detector/Transducer. It is an electronic detection system
used to measure the concentration of Methane, Propane, or Hydrogen and provide feedback and automatic exhaust
fan control to help reduce combustible gas concentrations in parking garages, maintenance facilities or other
commercial applications.
It is available in both a low voltage (GD-6) and line voltage (GD-12) option. The GD-xx is a low-level meter capable of
displaying in the range 0-50% LEL (Lower Explosive Limit) of Methane, Propane, or Hydrogen. The GD-xx has
selectable 4-20 mA output, buzzer and digital display options. The GD-xx is factory calibrated and 100% tested for
proper operation but can also be calibrated in the field.
The GD-xx is intended to be mounted on a 4 x 4 electrical box. It can operate in a stand-alone application or can be
connected to a building automation system, UL listed Control Panel, or other control device that accepts 4-20mA
analog input. The GD-xx is compatible with the Macurco DVP Control Panel.

1.2 List of warnings

Each person using this equipment must read and understand the information in this
user manual before use. Use of this equipment by untrained or unqualified persons or
use that is not in accordance with this user manual, may adversely affect product
performance.
Use only for monitoring the gas which the sensor and monitor is designed to detect.
Failure to do so may result in exposures to gases not detectable and cause serious
injury or death. For proper use, see supervisor or user manual, or contact Technical
Support at 1-844-325-3050.
This equipment may not function effectively below 0°F or above 125°F (-18°C or above
52°C). Using the detector outside of this temperature range may adversely affect
product performance.
This detector helps monitor for the presence and concentration level of a certain
specified airborne gas. Misuse may produce an inaccurate reading, which means that
higher levels of the gas being monitored may be present and could result in
overexposure and cause serious injury or death. For proper use, see supervisor or User
manual, or contact Technical Support at 1-844-325-3050.
High voltage terminals (120/240 VAC) are located within this detector, presenting a
hazard to service technicians. Only qualified technicians should open the detector case
and service the internal circuits. Ensure power is de-energized from the detector relays
prior to servicing the unit. Failure to do so may result in electrical shock.
Do not disassemble unit or attempt to repair or modify any component of this
instrument. This instrument contains no user serviceable parts, and substitution of
components may impair product performance.
