2 Use Instructions and Limitations
The GD-6 is a low voltage, dual relay combustible gas detector and automatic ventilation controller. The GD-6 uses a
microcomputer controlled, electronic system to measure the concentration of combustible gas, actuate relays and
provide a 4-20 mA output. The GD-6 has a low maintenance long life (5+ years) pellistor sensor and optional gas test
and calibration kits. The GD-6 is a low-level meter capable of displaying from 0-50% LEL of combustible gas.
WARNING
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.
NOTE: Combustible gas detectors will respond to a wide range of hydrocarbons, including aerosol sprays, cleaning
solvents, paint thinner and other common household items. Be alert to other hydrocarbons near the detector
before assuming that the unit is false alarming or is defective.
2.1 Use For
The GD-6 provides combustible gas detection and automatic exhaust fan, louver or valve control for automotive
maintenance facilities, enclosed parking garages, utility rooms, battery rooms, warehouses with forklifts and other
commercial applications. The GD-6 can be used stand alone, with the Macurco DVP-120 Detection and Ventilation
Control Panel, other 12 VAC or 24 VDC fire/security panels or building automation systems.
WARNING
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.
2.2 Do NOT use for
The GD-6 is not intended for use in hazardous locations or industrial applications such as refineries, chemical plants,
etc. Do not mount the GD-6 where the normal ambient temperature is below 0°F or exceeds 125°F (-18°C or above
52°C). The GD-6 mounts on a type 4S electrical box supplied by the contractor. Do not install the GD-6 inside another
box unless it has good air flow through it.
WARNING
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.
