2Maintenance• Be sure to conduct periodic inspection once within 6 months after installation, then once every year afterthat.
• Change the sensor if 100 % or more of deviation from effective range of the standard value criteria(e.g. 400 ppm 150 ppm) occurs.
• Change the sensor if no output occurs.

(1) Fixing the Mounting Plate
Screw either (A) or (B), and fix the Mounting Plate
to the outlet box, via outlet box cover located insidethe wall.
For screws, use M4 screw (2 pieces) and spring
washer provided.

Power Consumption
17 W
Operating Environment Temperature: 0 to 50
Humidity: 0 to 95 %RH (non-condensing)[Caution]
Do not use this sensor in an environment where dew condensation occurs.
Do not use this sensor in an environment where chlorinated and sulfidizing gases
are being generated.
Storage Environment Temperature: -30 to 60
Humidity: 0 to 95 %RH (non-condensing)[Caution]
Do not apply sustained pressure or shock to the cavity (gold-colored section)
