* The area classification only applies if the detector is installed using a junction box with an
internal volume less than or equal to 69 cubic inches and rated explosion proof for Class I,
Groups B, C, and D. The detector is not explosion proof if it is installed in a non-explosion
proof enclosure, such as in a conduit hub of a controller like the Beacon 200 or Beacon 800.

WARNING: If the detector installation is explosion proof, do not remove the sensor cap or
junction box cover while the circuits are energized unless the area is
determined to be non-hazardous. Keep the sensor cap and junction box cover
tightly closed during operation.
CAUTION: If you suspect the presence of the target gas in the monitoring environment,
use the calibration kit and the zero air calibration cylinder to introduce “fresh
air” to the sensor and verify an accurate zero setting.
