Use For; Do Not Use For - Macurco CD-6B User Instructions

Macurco CD-6B Manual (Rev-1.0) Eng
The CD-6B is a low-level meter capable of displaying from 0 to 5.0% vol. with a display resolution of 0.01% vol.
(measurement is % by volume) of CO
The CD-6B is factory calibrated and 100% tested for proper operation.
The CD-6B has the option to use automated background calibration (Abc) to set the clean air level on a regular basis.
If not using automated background calibration, the CD-6B requires a manual calibration process at a minimum of
once every year using the Macurco CD6B-FCK calibration kit.
Carbon dioxide is a colorless, odorless gas that is produced both by people exhaling CO
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
number of people present, how long an area has been occupied, the amount of outdoor fresh air entering the area
and other factors. CO concentrations 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 levels of the indoor environment. The amount of fresh air that should be supplied to a room
2
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.
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-6B provides CO detection and automatic ventilation control for buildings in non-hazardous locations
2
wherever 100 lbs or more of CO
The Awareness Alarm and Alarm 1 Relay is intended to locally warn users of high level of CO
Alarm 3 Relay are intended to sound remote alarm functions to warn building users of high CO
CD-6B is not compatible with Macurco DVP Control Panels. The three (3) dry contact relays can be connected back
to a Fire or security panel.
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.

2.2 Do NOT use for

The CD-6B is not intended for use in hazardous locations or industrial applications such as refineries, chemical
plants, etc. Do not mount the CD-6B where the normal ambient temperature is below 32°F or exceeds 121°F (0°C or
above 50°C). The CD-6B mounts on a type 4S electrical box supplied by the contractor. Do not install the CD-6B
inside another box unless it has good air flow through it.
