2 USER 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.
2.1 Use For
The CD-6"x" provides CO
2
applications. Carbon dioxide is a colorless, odorless gas that is produced both by people exhaling CO
coal, oil and wood. The outdoor concentration of carbon dioxide can vary from 350-450 parts per million (ppm) or higher in areas with
high vehicle traffic or industrial activity. The indoor CO
occupied, the amount of outdoor fresh air entering the area and other factors. CO
per million in areas with many people present for an extended period and where fresh air ventilation is limited. Outdoor "fresh" air
ventilation is important as it can dilute CO
depends on the type of facility and room. Ventilation should keep carbon dioxide concentrations below 1000 ppm and create indoor air
quality conditions that are acceptable to most individuals.
For applications storing or using CO2 tanks, the detector will provide notification in the event of a gas leak. Such applications include but
are not limited to: food storage, beverage dispensing, agriculture, fire suppression, medical, etc.
The CD-6H uses an automated background calibration program to set the clean air level on a regular basis. The CD-6H will maintain
accuracy if it is exposed to the "clean air reference value" (this reference value is the lowest concentration to which the sensor is exposed)
at least once per week.
The CD-6MC does not perform automated background calibrations and it is suggested to perform a Manual Calibration on the unit no
less than once per year using the Macurco CD6-FCK calibration kit.
Note: This applies when used in typical indoor ambient air. The CD-6"x" can be used stand alone, with the Macurco 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 Technical Support at
844-325-3050.
2.2 Do Not Use For
The CD-6"x" is not intended for use in hazardous locations or industrial applications such as refineries, chemical plants, etc. Do not mount
the CD-6"x" where the normal ambient temperature is below 32°F or exceeds 122°F (0°C or above 50°C). The CD-6"x" mounts on a
type 4S electrical box supplied by the contractor. Do not install the CD-6"x" inside another box unless it has good air flow through it.
This equipment may not function effectively below 32°F or above 122°F (0°C or above 50°C). Using the detector outside of this
temperature range may adversely affect product performance and result in sickness or death.
