4- 1. Before operation
Not only a first experienced client but also an experienced client shall keep the cautionary items. If not kept,
the trouble may cause and could not make normal gas detection.
4- 2. Installation place
When install, avoidthe direct sun beam place or that of drastic change of temperature. Because dew
takes place inside of instrument and it may not follow the drastic change of temperature.
As this is composed of fine electronics parts, install where the vibration and shock should not
take place and be stable.
Avoid to installing at the place where high frequency is generated around.

4- 3. Caution at system installation
Unstable power and noise may cause error of performance and alarm.
For the system to use this detector, it is required to make design based on this
manual description.
(1) Use stable power
While the system gets stable at power on and power failure, the external output and alarm contact may be on
and the care for it must be taken. In such case, use the standby battery or take an appropriate action in the
receiver side. Supply the following power to this detector.
Power voltage 100VAC- 15% to 220VAC+20% (50/60Hz)
Power failure Approx. 100msec.
tolerance time (For power failure of over 100msec, it re - starts.)
To warrant the continuous operation, install the standby
battery outside.
Others Do not connect with power involving high power load and high
frequency noise.
According to requirement, use line filter and separate it from
noise source.
(2) Designing to consider heat radiation
When install the closed self- standing control panel, mount th e fans in the upper and lower part.
Machine that grounding construction is n
