Use Instructions And Limitations; Use For - Macurco GD-6 Operation Manual

Macurco GD-xx Operation Manual
Using a certified gas with a concentration other than the one listed for this detector
when conducting a calibration verification test (bump test) will produce inaccurate
readings. This means that higher levels of the gas being monitored may be present and
could result in overexposure. For proper use, see supervisor or User manual, or
contact Technical Support at 1-844-325-3050.
The following steps must be performed when conducting a calibration verification test
(bump test) to ensure proper performance of the monitor. Failure to do so may
adversely affect product performance.
• When performing a calibration verification test (bump test) only use certified
calibration gas at the required concentration level.
• Do not test with expired calibration gas.
Do not cover or obstruct display or visual alarm cover.
•
Ensure sensor inlets are unobstructed and are free of debris
•
Failure to follow instructions outlined in this user manual can result in sickness or
death.

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.
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.
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.
