Leave the diagonal line area so that the installation space is reserved.
CAUTION
• It is recommended that installation points should be away from each other for 10 mm or more.
Intervals between installation points must be at least 5 mm.
• When you install more than one unit of the detector in a line, install them in a rack or wall that are not
influenced by vibrations.
When the detectors are installed side-by-side, if the rack or wall in which the detectors are installed do
not have enough strength, vibrations from the pumps inside the detectors cause resonance between
them. In this case, take preventive actions, for example, reinforcing the rack or wall.
