3 Installation Instructions
This detector helps monitor for the presence and concentration level of a certain specified
airborne gas. Misuse may produce an inaccurate reading, which means that higher levels of the
gas being monitored may be present and could result in overexposure and cause serious injury or
death. For proper use, see supervisor or User manual, or contact Technical Support at 1-844-325-
3050.
3.1 Location
Mounting height will be dependent on the application. For applications with CO
above the floor. For indoor air quality mount detector at breathing level, about 5 feet (1.5 meters) above the floor on a wall or
column in a central area where air movement is generally good. The unit, on average, can cover between 900 sq. ft. (83.62 sq.
meters) and 5000 sq. ft. (464.51 sq. meters) depending on the application. Applications with CO
should be closer to the 900 sq. ft. For indoor air quality and purposefully enriched areas, such as greenhouses, spacing can be up
to 5000 sq. ft. When determining the coverage area for each application, keep in mind that each application is going to be
different and needs to be evaluated to determine the number of detectors required to ensure proper coverage. Some of the
factors that affect the coverage area are application type, personnel work areas and movement, room size, air movement,
potential threat, mounting location, along with other site-specific factors that must be considered. Please check local
regulations or requirements prior to installation.
The CD-xxH/MC mounts on a 4x4 electrical box supplied by the contractor. Do not install the CD-xxH/MC inside another box
unless it has good air flow through it. DO NOT mount the CD-xxH/MC where the normal ambient temperature is below 32°F or
exceeds 122°F (below 0°C or above 50°C).
High voltage terminals (120/240 VAC) are located within this detector, presenting a hazard to
service technicians. Only qualified technicians should open the detector case and service the
internal circuits. Ensure power is de-energized from the detector relays prior to servicing the unit.
Failure to do so may result in electrical shock.
3.2 Installation

1. The CD-xxH/MC mounts on a 4" square (or 4x4) electrical box supplied by the contractor. DO NOT mount the CD-
xxH/MC inside another box, unless it has good air flow through it.
