Carbon Monoxide Transmitter
CY7200A
General
A carbon monoxide transmitter detects levels of the poi-
sonous gas (CO) and sends a real-time value to a control
system installed in commercial and residential buildings.
The CY7200A transmitter has wide applicability for the
detection of concentration of CO in indoor spaces. Typ-
ical applications include detection of CO in parking gar-
ages and recreation or office spaces within a building.
Features
The transmitter uses the constant-potential electrolytic
method to provide fast, highly accurate readings. The
presence of other gases does not affect its CO
concentration measuring capability.
It detects CO in concentrations as low as 0 to 60 ppm,
and is ideal for controlling indoor CO levels.
It is designed for wall mounting it is light and compact
and has a design that bled in with residential humidity
detectors and other sensors.
Used in combination with programmable controller, it
optimizes control of fans and other ventilating devices
to maintain safe and pleasant indoor environments.
The system also may help to prevent excess energy
consumption in parking lots.
