Installation Site
When installing in indoor parking lots, ensure the follow-
ing requirements are satisfied:
1) Air flow from the fan must reach the CY7200A.
2) Install 2 to 2.5 m above floor level.
3) Install in a position where the CY7200A does not come
into direct contact with exhaust fumes.
4) Do not install near fan.
5) Install at least one CY7200A sensor on each floor of a
multi-story indoor garage. Install at least one sensor
in each area, if partitions segregate a floor into
multiple spaces.

Installation (main unit)
1) Fasten the painting clearance cover with 66.7 mm
pitch (box cover, JIS C8336) on a standard outlet box.
2) Fasten the mounting plate on the painting clearance
cover.
3) Fasten the base plate on the mounting plate.
4) Connect the wires.
5) Remove the cover from the sensor/transmitter and
fasten the sensor/ transimitter on the base plate.
6) Fit the cover to the sensor/ transmitter.
Note: Order the base plate separately

Fig.7 Wiring
Install dust filter
Always install a dust filter when the sensor is to be in-
stalled in locations, such as bus terminals, where dust
and other contaminants are present.
Generally there is no need to install at dust filters on
sensors installed in underground parking lots.
NOTE:
Follow the instructions when wiring.
Do not break or short wiring. Faulty wiring may
cause damage to the sensor.
Do not incorrectly wire 24V DC and 100/ 200V
AC.
Put the controller electric input between the
sensor side (blue) and electric side.
Set the Co sensor element ion circuit.
1) Turn the power OFF and stop power supply.
2) Remove sensor cover.
3) Put filter cover inside filter. Make net face toward the
element.
4) Cover sensor. Insert screws vertically.
5) Tighten both screws evenly and in turn.
6) Check filter cover is correctly installed on element
before attaching to cover.
NOTE:
Always dispose of the sensor in an appropriate
manners. The CY7200A should be treated as
industrial waste, sensor contains sulfuric acid.
