4-2. Precautions for installation sites
CAUTION
Do not install the alarm system in a place exposed to direct sunlight or sudden changes in the
temperature.
When selecting installation points, avoid a place where it is exposed to direct sunlight or radiant
heat (infrared rays emitted from a high-temperature object), and where the temperature
changes suddenly. Condensation may be formed inside the alarm system.
When selecting installation points, avoid a place where the alarm system is exposed to liquids,
such as water, oil and chemicals.
Do not install the alarm system in a place where the temperature drops below -10
°
C or rises
over 50
°
C.
The operating temperature of the alarm system is -10 to 50
°
C. The alarm system must be
installed in a stable place where the operating temperatures are maintained and do not change
suddenly.
Do not install the alarm system in a place with vibrations or shocks.
The alarm system consists of sensitive electronic parts. It must be installed on a stable place
without vibrations, shocks and risk of drop, etc.
Keep the alarm system (and its cables) away from noise source devices.
When selecting installation points, avoid a place where high-frequency devices exist.
Do not place the alarm system next to a noise source device.
Do not run cables parallel to each other.
Do not place cables close to each other.
Do not install the alarm system in a place where detectable gases stay around.
Do not install the alarm system and perform detection in a place where detectable gases
remain.
Do not install the alarm system in a place where maintenance of the alarm system cannot be
performed or where handling the alarm system involves dangers.
Regular maintenance of the alarm system must be performed.
Do not install the alarm system in a place where the machinery must be stopped when
maintenance is performed in its inside, where parts of the machinery must be removed to
perform maintenance, or where the alarm system cannot be removed because tubes, racks,
etc. prevent access to it.
Do not install the alarm system in a place where maintenance involves dangers, for example,
near a high-voltage cable.
Do not install the alarm system in machinery which is not properly grounded.
Before installing the alarm system in machinery, the machinery must be grounded properly.
