CAUTION
This is a precision device. Because the detector may not provide the specified performance in some
places (environments), check the environment in the installation point, and then take appropriate
actions if necessary.
Because the detector plays an important role for safety and disaster prevention, as many units of
the detector as needed must be installed in appropriate points.
Because points where gases leak and remain easily are different depending on the types of gases
and the working areas, please decide carefully on installation points and the number of units to be
installed.
