USE INSTRUCTIONS AND LIMITATIONS
Each person using this equipment must read and understand the information in these User Instructions before use. Use of this
equipment by untrained or unqualified persons, or use that is not in accordance with these User Instructions, may adversely affect
product performance and result in sickness or death.
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.
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.
Use only for monitoring the gas which the sensor and instrument are designed to monitor. Failure to do so may result in exposures to
gases not detectable and cause sickness or death. For proper use, see supervisor or User Instructions, or call Macurco Technical
Service at 1-877-367-7891.
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 (-18C or above 52C). 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.
This equipment may not function effectively below 0F or above 125F (-18C or above 52C). Using the detector outside of this
temperature range may adversely affect product performance and result in sickness or death.
General Description
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.
