Use as an emergency
light / night light

The light is normally used as a night lightand as an emergency light in case of a
blackout

When the surrounding area is dark due to a blackout, the lightis lit at maximum brightness as an emergency light. Illuminating brightly, it provides customers a sense of security. In
addition, as the night light can be adjusted in 3 steps, you canuse it at the optimal brightness according to the environment
and lifestyle scenario of your installation location.

In the event of a blackout, a voice alarm “Teiden-ga-hassei-shimashita.” (A power failure has occurred) will be given poweredby the built-in battery, and if the blackout is at night, the emergency light will be lit (at maximum brightness) to provide notiﬁcation.
In addition, when the power supply is restored, a voice alarm“Teiden-ga-fukkyu-shimashita.” (Power is restored) is given,

CO (carbon monoxide) is generated at the initial stage of a“smoke fire”, etc. An alarm is raised upon detection of CO
being generated.

No electricity is required, so
monitoring is maintainedeven during a blackout

As it is battery-powered, power supply from an electric outlet
is not necessary and no electricity cost is incurred. In addition, monitoring can be continued even during a blackout
caused e.g. by an earthquake.

Because it is cordless, it
can be installed anywhere

A smart aesthetic appearance is realized by the cordless design. It can be installed anywhere because it does not need
to be connected to an outlet.
11（英語）カラーページ.indd 13

Reliable alarm without
beeping

Due to the adoption of an electrochemical sensor, the alarm
does not react to miscellaneous gases and will not be activated unless the CO really reaches a dangerous concentration.
In addition, by integrating the CO density and detection time,
the COHb (carboxyhemoglobin) concentration in humanblood is estimated, and an accurate alarm is given before it
exerts a dangerous effect on the human body. (See Page 42)

Compact and slim design
saves space

The system has a compact, space-saving design. In addition, it can be installed anywhere and works even during a
blackout as it is a battery type.

Reliable and easy-to-understandalarm sounds and audio

An alarm sound (“Pee Po Pee Po”) and voice guidance will
inform you of the risk of CO poisoning. Useful in case of
emergency.

Town Gas Supply System

Town Gas Supply System
Before town gas isdelivered(Source: Gas Energy Newspaper July 15, 2019 issue)

Currently, most of the natural gas consumed in Japan is LNG (Liquefied Natural Gas) imported
LNG produced overseas is imported in special tankers and received at a LNG terminal. It thenfactories, buildings, households, etc. via a piping network from high to low pressure.
In some areas where there are no connecting pipes or LNG receiving terminals, lorries
vaporization, calorific adjustment and odorization before delivery.

● Supply system before town gas is delivered

Transport

Stockpile/vaporization

Highpressure pipe

LNG tank
LNG tanker
Mined natural gas is converted into
natural gas at -162 °C and thentransported mainly to Japan from thecountry of origin over 7 to 30 days (2 to
3 days from Sakhalin).

The world's largest 230,000 kl tankholds an amount that is equivalent to theannual volume used by about 330,000
households.
The size is big enough to accommodate
the castle tower of Osaka Castle including
the foundation.
As LNG is stored as a liquid at -162 °C, a
special alloy that can withstand ultra lowtemperatures is used inside the tank.

LNG
vaporizer
The liquid is vaporized byspraying seawater onto pipes inwhich LNG flows at a temperatureof -162 °C.

Governor station(High to medium pressure)
A governor is a device to regulate thepressure. A high pressure governor isinstalled in the governor station to lower
the pressure to medium pressure.

Tanker truck
In areas where pipes have not been installed,
natural gas is supplied in LNG tanker trucks.

Trivia Japan’s LNG imports
Approx. 80 million tons areimported annually!

Production process of town gas

Before town gas is madeLNG (Liquefied Natural Gas) that has been liquefied and transported isstored in an LNG tank, then vaporized and adjusted for calorific value,
before a specific odor is added to turn it into town gas.

Vaporization
Changes from aliquid to a gas.

Calorieadjustment
LPG is added tonatural gas to adjust
the calorific value tothe prescribed value.

Odor
Even in the event ofa gas leak, an odor

Town Gas

Japan imported 80.55 million tons of LNG in 2018.
Although the volume has been declining since reaching a peak of
89.07 million tons (FY2014) , a high level of imports exceeding 80
million tons has continued since fiscal year 2011 when it surged
due to the shutdown of nuclear power plants following the Great
Eastern Japan Earthquake.
In 2018, there were 18 importing countries, the largest of which wasAustralia at 29.44 million tonnes, accounting for 36% of all imports.

(Source: Gas Industry Statistical Annual Report of the Agency for Natural Resources and Energy)

In April 2017, the gas retail industry was fully liberalized, allowing
all businesses to choose a gas retailer, including households
who had previously been unable to select their supplier for town
gas. In conjunction with this, a licensing system was introducedin the previously regulated town gas industry, which classified thetown gas industry into three categories: gas production industry,general gas distribution industry, and gas retail industry.
As the three major town gas companies have a large number ofcustomers and an extensive pipeline network, the pipeline sector
is expected to be legally separated from the rest from 2022
onwards due to the need for neutrality.

Gas Meters

A Ventilation Warning Alarm for Commercial is an alarm that generates
an alarm upon detecting carbon monoxide (CO) being generated due toincomplete combustion in a commercial kitchen appliance.
By integrating the CO density and detection time, the COHb
(carboxyhemoglobin) concentration in human blood is estimated, and an
accurate audible alarm is given before it exerts a dangerous effect on thehuman body.
Installation is easy as it is battery-powered and does not require an electricaloutlet.

Boiled noodle machine60

Detection time (min.)*A typical CO alarm is extremely sensitive to CO, so it is frequently triggered by even a small amount of CO generated.
Fearing that this will impede operations, there is a risk that the user may turn off the power supply of the alarm.

Automatic Gas Shutoff System

Automatic Gas Shutoff System[What is an Automatic Gas Shutoff System]

Ventilation Warning
Alarm for Commercial

An “Automatic Gas Shutoff System” can automatically shut off the gas in an
emergency, e.g. when a gas leak occurs, by being linked to the gas alarm. By
linking it to a ventilation warning alarm for commercial, the gas supply can be
shut off when there is an imminent danger of poisoning by carbon monoxide.
In addition, opening/closing of the shutoff valve and leak inspection of the gas
pipes can be automatically performed simply by operating the switches of thecontroller. Moreover, it is also possible to connect it to a simple automatic fire
extinguishing device for hoods, a gas shutoff display panel in the control room,
or a remote closing switch. These connections automatically shut off the gas
in addition to extinguishing the fire if a hood fire occurs, allowing the opening/closing status of the shutoff valve to be monitored by the controller in thecontrol room. The system also allows the gas to be shut off from the control
room.

 ince a “gas leak” is denoted as a “pressure drop
downstream of the valve”, the expression is therefore as
follows•Large leak → (Downstream of valve) Large pressure drop
•Medium leak → (Downstream of valve) Medium pressure
