Application Requirements
IMPORTANT:
The CD-Wxx-00-0 Series
transmitters are intended to provide input to
equipment under normal operating conditions.
Where failure or malfunction of the transmitter could
lead to an abnormal operating condition that could
cause personal injury or damage to the equipment or
other property, other devices (limit or safety controls)
or systems (alarm or supervisory) intended to warn
of, or protect against, failure or malfunction of the
transmitter must be incorporated into and maintained
as part of the control system.
FCC Compliance Statement
This equipment has been tested and found to
comply with the limits for a Class A digital device
pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection
against harmful interference when the equipment is
operated in a commercial environment. This
equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in
accordance with the instruction manual, may cause
harmful interference to radio communications.
Operation of this equipment in a residential area is
likely to cause harmful interference, in which case
the user will be required to correct the interference at
his/her own expense.
Canadian Compliance Statement
This digital apparatus does not exceed the Class A
limits for radio noise emissions from digital
apparatus set out in the Radio Interference
Regulations of the Canadian Department of
Communications.

Installation
Parts Included
Wall Mount Carbon Dioxide (CO
(includes base, PCB, and cover)
Drywall Mounting Kit (includes two each
No. 6-20 x 1-1/4 in. pan-head, self-tapping screws,
spring clips, and spacers)
Mounting
The CO
transmitter is shipped ready for installation
2
onto a standard wallbox or for surface mounting with
the Drywall Spring Clip Mounting Kit (included).
IMPORTANT:
Avoid touching or applying force
to the components on the Printed Circuit Board
(PCB). Handle the board by the edges only.
Location Considerations
This device mounts either to a U.S. wall box or directly
to a wall surface:
Locate the device on an inside wall, free from drafts,
and out of direct sunlight. The transmitter is shock and
vibration resistant; however, be careful not to drop the
unit or mount it where it could be exposed to excessive
vibration. The following ambient operating conditions
apply:
Temperature: 23 to 113°F (-5 to 45°C)
Humidity: 0 to 85% Relative Humidity (RH),
non-condensing 85°F (29°C) maximum dew
