3 Installation and Operating 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
A CX-xx is normally mounted 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
approximately 5,000 sq. ft. (465 sq. meters) to 7,500 sq. ft. (697 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. 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 CX-xx mounts on a 4x4 electrical box supplied by the contractor. Do not install the CX-xx
inside another box unless it has good air flow through it. Do NOT mount the CX-xx where the normal
ambient temperature is below 0°F or exceeds 125°F (below -18°C or above 52°C).
High voltage terminals (120/240 VAC) are located within this detector (CX-12),
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.
