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.

Use For

The CD-6 provides CO2 detection and automatic ventilation control for conference rooms, classrooms, meeting halls or similar
applications. Carbon dioxide is a colorless, odorless gas that is produced both by people exhaling CO2 as well the burning 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 CO2 level depends upon the number of people present, how long an area has been
occupied, the amount of outdoor fresh air entering the area and other factors. Carbon dioxide concentrations indoors can vary from
several hundred parts per million to over 1000 ppm 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 CO2 the indoor environment. The 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. The CD-6 uses an automated
background calibration program to set the clean air level on a regular basis. The CD-6 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.
Note: This applies when used in typical indoor ambient air. The CD-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 Technical Service at 1-
877-367-7891.
Do Not Use For
The CD-6 is not intended for use in hazardous locations or industrial applications such as refineries, chemical plants, etc. Do not mount
the CD-6 where the normal ambient temperature is below 32°F or exceeds 122°F (0C or above 50C). The CD-6 mounts on a type 4S
electrical box supplied by the contractor. Do not install the CD-6 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.

General Description

The CD-6 is a low voltage, dual relay Carbon Dioxide (CO2) detector and automatic ventilation controller. The CD-6 uses a
microcomputer controlled, electronic system to measure the concentration of CO2, actuate relays and provide a 4-20 mA output. The
CD-6 has a low maintenance long life (10+ years) non-dispersive infrared (NDIR) sensor and optional gas test kits. The CD-6 is a low
level meter capable of displaying from 0-2000 ppm of carbon dioxide.
