1. Product Overview
Thank you for purchasing a smart gas detector, Smart Safety Ball
(S2B-300).
With the newly designed portable gas detector, Smart Safety Ball,
workers can roll or hang down this gas-detecting ball into the enclosed
area before entering the space. They can monitor the gas concentration
of oxygen(O2) and toxic gas(CO, H2S) remotely in real time using a
smartphone application. Therefore, the workers can be notified the
presence of harmful gas beforehand.
Main Features
wSmart Safety Ball is easy to carry on, since it is small and light
(“about 99.5g”), and continuously operates “for 2 years” without
charging or battery replacement.
wAs mentioned above, three types of gases (“O2, CO, H2S”) can be
measured simultaneously, and remote monitoring can be performed in
the range of 30 ~ 100 meters (depending on the circumstances).
wThis new shape of gas detector is developed for an use-case at the
enclosed and narrow space, before entering themselves, by rolling (or
hanging down with a strap) the product inside.
wAlso, in the case that a user wants to monitor gas concentration at a
fixed spot, the user can attach the Smart Safety Ball to any metallic
equipment nearby using the magnetic of the product.

3. User Precautions
[ WARNING ]
DO NOT OPEN OR REPLACE BATTERY WHEN EXPLOSIVE ATMOSPHERE IS PRESENT.
POTENTIAL ELECTROSTATIC CHARING HAZARD – CLEANING SHALL BE DONE WITH A
DAMP CLOTH.
Warning
§When operating Smart Safety Ball for the first time, or turning it on
again after not using it for a long period of time, it takes some time
for stabilization until it indicates accurate results. (Turn on the product
in the clean atmospheric environment without harmful gas)
§Do not use this product for gas measurement or as gas analyzer since
it is a detection and alarm device. In addition, since it is a portable
device, we are not responsible for any problem that may occur if it is
used as a fixed or mobile device.
§Arbitrary dissembling of products or replacement of parts may cause
detrimental damage on the products. Direct touch of internal circuit
may cause static electricity, resulting in circuit damage. Contact
manufacturer if the sensor or the battery require replacement.
§Do not power off the product(for a long time) since this product carries
out automatic calibration of the gas sensor. It is recommended to keep
the gas detector in a safe place with the power on when not in use.
§
Improper handling or use of the product may cause reduction of the
service life or inaccurate gas detection.
(Example of improper handling:
storage near hot, flammable or toxic substance, soaking in the water or
impact on the product case or gas measurement hole, etc.)
§This product has been manufactured without its display and you can
check the detection results of oxygen and toxic gas using “Safety Ball”,
the dedicated Bluetooth application(hereinafter dedicated app) at your
smartphone. You can download the dedicated app at Google PlayStore
or Apple AppStore for free. Be sure to download it in a safe
place(explosion-proof area).
§This product operates as a stand-alone gas alarm and gives an alarm
according to situation in case of oxygen deficiency or toxic gas leakage.
Be sure to keep the dedicated app of the smartphone running when
using this product in order to escape the place quickly in case of
emergency and to automatically respond to it.
§Some functions such as sending situation message may be restricted in
the shielded places where incoming and outgoing call of smartphone is
not possible.
§Various functions implemented through the smartphone may be lost if
distance between this product and smartphone is so far that Bluetooth
signal cannot reach. Use it only within the communication distance
between the devices, and check the normal operation of app.

4. How to Use
Product Type: Smart Gas Detector
Model: S2B-300
Measuring Gas: Oxygen (O2) / Carbon monoxide (CO) / Hydrogen sulfide (H2S)
4.1. Device Startup (Activation)
wPress the button for about 3 seconds to turn on the power(green LED on).
Release the button when red LED turns on with startup alarm sound. After that,
red LED will blink in the interval of 3 seconds and normal operation will start.
wPress the button for about 10 seconds to turn off the power(LED turns on). The
product power is cut off with shutdown alarm sound. (Power shutdown is not
recommended unless there is a special purpose such as calibration.)
4.2. Standby Mode
wRight after the power is on, S2B-300 operates in Stand-by mode.
wIn the standby mode, S2B-300 does not operate as a gas detector and performs
internal error diagnosis and sensor stabilization.
wWhen stabilization is over, the standby mode automatically exits and S2B-300
enters the detection mode.
wWhen span calibration or firmware update is required, it could be performed in
this standby mode.(See “Appendix D” of this manual for details. )
[LED Operation Pattern]: red LED blinks in the interval of 3 seconds
4.3. Detection Mode
wIn Detection mode, Smart Safety Ball operates as a gas detector.
wTo check the concentration of detection, turn on the Bluetooth function of
smartphone and run the dedicated app.
wWhen the concentration of gas is beyond the certain level, the product triggers
the alarm. If the dedicated app is on, alarm also works on the dedicated app.
wSee Clause 4.4 on page 7 for criteria of alarm triggering and operation pattern.
[LED Operation Pattern]: green LED blinks every 3 seconds

4.4. Alarm Mode
wRed LED blinks according to the buzzer pattern in Alarm Mode.
wIn case of A1/A2 alarm, press the button to temporarily turn off the buzzer sound.
If the concentration of gas returns to the normal value, the alarm is automatically
terminated.
wTWA (8 hour cumulative concentration) and STEL (15 minute cumulative
concentration) value are defined for concentration of toxic gas (CO or H2S). Use
the dedicated app to turn off the alarm. See the user’s manual of dedicated app
for details.

4.5. Recommended Usage
w”Be sure to“ check the LED pattern before using the product to see whether
Smart Safety Ball operates in detection mode(green LED blinks). If there is no
separate operation, the product operates in the detection mode and measures the
concentration of gas real time.
wSince this product can operated ”continuously for 2 years“ and performs long-time
automatic calibration of the oxygen sensor, it is recommended to keep Smart
Safety Ball with power on in a safe place when not in use.
wSince this product does not require ”battery replacement or charging“, you can
wear this on ”safety helmet, clothes and equipment“ using the accessory clip
provided with this product and always carry the gas detector in the working
environment.
wIn case of an alarm, respond to the situation properly such as evacuation from
the relevant place in order to prevent suffocation.

※ Cautions on Performance of Gas Detector
wRefer to “Product Specification” page and use this product within the
recommended temperature, humidity and air pressure.
wResults of detection may be inaccurate in the “environment” where
temperature, humidity or air pressure rapidly change. Adapt to the
environment and use after the indication of the gas concentration is
stabilized.
wDo not use in “high-concentration environment” or for the gas beyond
measurement scope when detecting the concentration of gas. This may
shorten the service life of gas sensor inside the product and require
additional calibration.
wDo not use this product near the place where “strong electromagnetic
waves” exist (ex: base station). It may cause an error in the results of gas
detection, connection with or operation of smartphone.
※ Specific Conditions of use
i. The equipment is a hand-held & portable device. Where a static-generating
mechanism is identified, such as repeated brushing against clothing, then
suitable prevautions shall be taken, e.g. the use of anti-static footwear.
ii. As aluminum is used at this equipment, ignition sources due to impact and
friction sparks could occur, this shall be taken into account when the
requirement is used in zone 0 location
iii. Also, the included Bluetooth is only for use in the safe area. It means that
the measured gas value can not be confirmed, when the user enters to
zone 0 loction or a placte where possessing smart-phone is not permitted.
However, the product operates independently without smart-phone and alert
an alarm when a warning situation occurs.

after activation and to store in the clean and safe place.
wKeep the area around the measurement hole of gas sensor clean.
Calibration
wIt is recommended to perform calibration every 6 months after
start-up(activation).
wCalibration is conducted using the dedicated app and test gas of
specific concentration is required.
wSee “Appendix D” of this manual for the calibration process.
