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 about 900 sq. ft. (83.62 sq.
meters). The coverage depends on air movement within the room or facility. Extra detectors may be needed near any areas
where people work or where the air is stagnant. 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

3.2.1 6-Series Low Voltage
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.
2. Connect the CD-6H/MC to Class 2 power supply only. It is suggested to use a dedicated transformer for powering the
unit or units because of possible interferences from other devices on the same power supply.
3. Connect the CD-6H/MC to the control cables with terminal plugs. When making connections, make sure the power is
de-energized.
4. There are two terminals for Power: 12 to 24 VAC or 12 to 32 VDC, with no polarity preference.
5. There are two terminals for the dry alarm relay contacts, again with no polarity preference. The alarm relay can switch
up to 0.5 A 120 V, or 60 VA. The alarm relay is activated if gas reaches or exceeds the alarm settings. See section
