OVERVIEW
THE WORLD’S FIRST EVERYTHING DETECTOR
What is G7 Insight?
G7 Insight is a simple solution that bundles industry-leading gas detection with
automated compliance and business analytics tools. For the rst time ever, the days of
manually collecting data from the eld, reviewing spreadsheets and compiling reports
are behind you.
With just a few minutes of connectivity per day, all data automatically recorded by
G7 devices in the eld is uploaded to the Blackline Safety Network for automatic
compilation and report generation.
What are real-time features?
Real-time safety monitoring leverages location technology, communications and live
data to provide complete transparency and control over your safety program. Real-time
features utilize G7 devices’cellular or satellite connectivity, connecting people in the
eld with live monitoring teams in real time — ensuring no call for help will ever go
unanswered again.
In the event of an safety incident or gas exposure, monitoring personnel can see what
has happened, and communicate with workers directly via two-way voice calling or text
messaging through their G7 device.
BLACKLINE SAFETY NETWORK
How am I connected?
The Blackline Safety Network is a cloud-hosted system comprised of 2G/3G cellular
networks, satellite networks, our Blackline Live™ web portal application, your monitoring
account and your G7.
G7 devices require an active service plan in order to connect to the Blackline Safety
Network. Depending on your needs and requirements, various service plan options are
available such as 24/7 safety monitoring by Blackline’s Safety Operations Center and
two-way voice communication. Contact your organization’s safety professional for more
information regarding the details of your service plan.

G7 TECHNICAL USER MANUAL || 5
BLACKLINE LIVE WEB PORTAL
What is Blackline Live?
G7 utilizes the cloud-hosted Blackline Live web portal to monitor and manage all your
workers and devices, as well as deliver reports and business analytics insights.
With Blackline Live’s real-time alerting and live map with employee locations, you can
quickly locate and respond to a worker in distress. Real-time alerts show the employees
location on the map with the type of alert, enabling your team to eciently send help.
Blackline Live also allows you to create and customize conguration proles that
determine how a device or a group of devices operates in the eld. Similarly, alert
proles are set up to determine what contacts should be notied in the event of an
incident and what response protocol monitoring personnel will follow to ensure your
team gets the help it needs.
Blackline Live keeps track of alert history, calibrations and bump tests, eliminating the
need to manually retrieve data logs from the eld.
Blackline Live allows you to tailor user access depending on employee roles: employee,
supervisor, administrator and monitoring team. This ensures that everyone has access to
the right tools to accommodate their role in a comprehensive monitoring program.
What is Blackline Analytics?
With Blackline Analytics, review data collected from your device eet to make decisions,
follow up with your team and ensure everything is running smoothly. Choose from a
number of dierent reports and lters to explore your data.
Blackline Analytics is built directly into the Blackline Live portal, allowing anyone with
login access to see their own organization’s data, as well as client data. If users have
only been given access to specic groups of devices, they will only see data attached to
those particular devices.

G7 TECHNICAL USER MANUAL || 15
GAS DETECTION
Included with your G7 Single-gas or Multi-gas cartridge is a calibration cap and
tubing for bump tests and calibrations. Alternatively, bump tests and calibrations can
be completed using a G7 Dock. Only perform bump test and calibrations in a safe
environment. For more information and instructions on bumping or calibrating with
G7 Dock, refer to the G7 Dock technical user manual.
BUMP TEST
What is a bump test?
It is safe practice to regularly test gas sensors by applying the target gas. G7’s bump test
also tests the operation of light, sound and vibration indicators. The bump test schedule
depends on your company’s safety policy. G7 automatically communicates bump test
data to the Blackline Safety Network, and will remind you when a bump test is overdue.
The bump test schedule is congurable.
NOTE: To meet CSA LEL performance standard, you are required to bump test before
each day’s use. Blackline recommends you do not exceed 30 days without a bump test.
How do I bump test?
1. Attach tubing to the calibration cap
2. Ensure the other end of the tubing is attached to a xed ow regulator on the gas tank

G7 TECHNICAL USER MANUAL || 17
CALIBRATION
What is calibration?
Gas sensors periodically need to be calibrated by applying a known concentration of
gas for a set amount of time. This procedure ensures the gas sensor can accurately
detect gas levels throughout its operating life. The calibration schedule depends on
your company’s safety policy. Blackline recommends not exceeding 180 days without
a calibration.
How do I calibrate?
1. Attach tubing to the calibration cap
2. Ensure the other end of the tubing is attached to a xed ow regulator on the gas tank
3. On your G7, press the OK button to enter the main menu
4. Use the arrow buttons to navigate to gas options, press OK
5. Use the arrow buttons to navigate to calibration, press OK

NOTE: If you see a calibration fail message on your LCD screen, try the calibration again. If
the error persists, please contact our Customer Care team.

18 || G7 TECHNICAL USER MANUAL
BUMP TEST & CALIBRATION REMINDER WINDOW
What is the bump test and calibration reminder window?
A bump test and calibration reminder window can be customized from G7’s
configuration profile in Blackline Live. This setting will prompt the device to show
a bump test or calibration reminder alarm upon startup if one of these tests is due
within the configured window of time.
What is the purpose of the bump test and calibration reminder window?
Enabling this feature will help ensure G7 goes into alarm upon startup instead of
while it is in use in the field. If you have a daily bump interval your bump test will
be due in 24 hours. However, if you start your shift 2 hours early the following day,
you will not be prompted to bump your device as 24 hours has not elapsed. When it
becomes due, you may already be out in the field without bump test materials. If you
have a 2 hour bump test/calibration reminder window, G7 will go into yellow warning
alarm for bump test due on startup when the bump is due within this 2 hour window.
BUMP TEST AND CALIBRATION LOCK
What is the bump test and calibration lock?
In the case that an organization wants to make the device unusable when it is out of
compliance, the calibration or bump test lock can be enabled from G7’s configuration
profile in Blackline Live. This feature locks the device’s screen and all functionality
when a bump test or calibration is due on startup. This means the user cannot use
their device in any capacity (including gas readings, SOS latch, message sending) until
it has been bump tested or calibrated.
What if a bump test or calibration is due during my shift?
If a bump test or calibration comes due during your shift (not on startup), the device
will not lock as this is a safety hazard, since the user will not be able to use G7 to call
for help. The device will go into a yellow warning alarm for bump test or calibration
due, and the message will display in the banner, but the device will remain fully
functional.

G7 TECHNICAL USER MANUAL || 19
ZERO SENSORS
What is zeroing?
If G7 is not reading zero and you know you are in an atmosphere with no gas, your gas
sensor readings may have shifted. If this happens, it is best to calibrate your sensors. If
you are unable to preform a calibration, you can zero your sensors to reset the baseline.
G7 can be congured to automatically or manually zero on start-up when you turn on
your device from the conguration prole in Blackline Live.
NOTE: The baseline reading for oxygen is 20.9.
How do I zero sensors?
1. On your G7, press the OK button to open the main menu
2. Press the arrow buttons to navigate to gas options, press OK
3. Use the arrow buttons to navigate to zero sensors, press OK
4. Press the up arrow to begin zeroing. Do not apply any gas.
5. The LCD screen will let you know once zero is complete
NOTE: If you see a zero incomplete message on your LCD screen you may be in an
environment with gas levels, or your cartridge may need replacement.
PID TARGET GASES
What are target gases?
Photoionization (PID) sensors can be used to detect a large range of gases. A target
gas refers to the specific gas you are using trying to detect. G7’s readings will be
adjusted based on the target gas it is configured to detect.
How do I set G7’s target gas?
G7’s PID sensor’s target gas is set from the configuration profile in Blackline Live.
Under the photoionization detector section of the gas sensor settings card, you can
choose an existing target gas or set a custom target gas.
Where do I see which target gas G7 is detecting?
The target gas G7 is configured to use can be seen in two places:
On startup
In the gas options menu, under gas info > VOC target
In both of these places, G7’s screen will display the target gases name, as well as its
correction factor.

20 || G7 TECHNICAL USER MANUAL
GAS DETECTION FEATURES
Once you have completed a bump test and calibration, G7 is ready to monitor and notify
you of gas exposure. Gas detection alarms will notify you with either a yellow warning alarm
or a red alert depending on the gas level measured. All settings are customizable in Blackline
Live. Speak to your safety supervisor to learn about how your gas features are congured.
YELLOW WARNING ALARM GAS FEATURES
LOW WARNING ALARM FOR GAS
When does G7 trigger a low yellow warning alarm for gas?
When gas levels reach the low concentration threshold configured by your safety
supervisor, G7 will inform you with a yellow warning alarm every two minutes until
gas levels are reduced.
NOTE: A G7 with O2sensors will trigger low warning alarms in oxygen-decient and
oxygen-enriched atmospheres. An oxygen-decient atmosphere poses a risk of
insucient oxygen for breathing. An oxygen-enriched atmosphere presents an
increased risk of explosion.
