Macurco CD-xx H/MC Manual

2 Use Instructions and Limitations

The Macurco CD-xxH/MC a dual relay Carbon Dioxide (CO
voltage options. The CD-xxH/MC has selectable 4-20 mA output, buzzer and digital display options. It is an electronic detection
system used to measure the concentration of Carbon Dioxide and provide feedback and automatic ventilation control to help
reduce CO concentrations in conference rooms, classrooms, meeting halls or similar applications. The CD-xxH/MC is a low-level
2
P P
meter capable of displaying from 0-5000 ppm (parts per million) of Carbon Dioxide. The CD-xxH/MC is factory calibrated and
100% tested for proper operation.
The CD-xxH uses an automated background calibration program to set the clean air level on a regular basis.
The CD-xxMC has the same setting and features of the CD-xxH with the addition of being able to perform a manual calibration.
The CD-xxMC requires a manual calibration process at a minimum of once per year using the Macurco CD6-FCK calibration kit.
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.

2.1 Use For

The CD-xxH/MC provides CO
similar applications. Carbon dioxide is a colorless, odorless gas that is produced both by people exhaling CO
of gasoline, 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
how long an area has been occupied, the amount of outdoor fresh air entering the area and other factors. CO
indoors can vary several hundred parts 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
amount of fresh air that should be supplied to a room 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 CO
include but are not limited to food storage, beverage dispensing, agriculture, fire suppression, medical, etc.
The CD-xxH uses an automated background calibration program to set the clean air level on a regular basis. The CD-xxH 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-xxMC 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.
N ote: This applies when used in typical indoor ambient air. The CD-xxH/MC can be used stand alone, with the Macurco
4 2 T 4 2 T
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.
