Installation and Operating Instructions
WARNING
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
2
tanks, mount height should be
about one foot 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 5,000 sq. ft. (465 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-6B mounts
on a 4x4 electrical box supplied by the contractor. Do not install the CD-6B inside another box unless it has good air
flow through it. Do NOT mount the CD-6B where the normal ambient temperature is below 32°F or exceeds 121°F
(below 0°C or above 50°C).
WARNING
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-6B mounts on a 4” square (or 4x4) electrical box supplied by the contractor. Do not mount the CD-6B
inside another box, unless it has good air flow through it.
2.
Connect the CD-6B to Class 2 Listed 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-6B 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. The alarm relays can switch up to 2.0 A load, up to
240 VAC or 30 VDC. The alarm relays are activated if gas reaches or exceeds the alarm settings. See section
