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.

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 eciently send help.
Blackline Live also allows you to create and customize conguration proles that
determine how a device or a group of devices operates in the eld. Similarly, alert
proles are set up to determine what contacts should be notied 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 dierent 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 specic groups of devices, they will only see data attached to
those particular devices.

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 congurable.
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.

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

the error persists, please contact our Customer Care team.
G7 TECHNICAL USER MANUAL || 17
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.
18 || G7 TECHNICAL USER MANUAL
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 congured to automatically or manually zero on start-up when you turn on
your device from the conguration prole 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.
G7 TECHNICAL USER MANUAL || 19
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 congured.
YELLOW WARNING ALARM GAS FEATURES
Rapid Blinking
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 O
oxygen-enriched atmospheres. An oxygen-decient atmosphere poses a risk of
insucient oxygen for breathing. An oxygen-enriched atmosphere presents an
increased risk of explosion.
20 || G7 TECHNICAL USER MANUAL
sensors will trigger low warning alarms in oxygen-decient and
2
UNDER LIMIT
When does G7 trigger an under limit yellow warning alarm?
If a gas sensor’s baseline shifts, it’s reading will shift accordingly and become
unreliable. When this happens, the presence of gas can still be measured, but cannot
be converted into an accurate reading. G7 will inform you of such an event with
a yellow warning alarm. A calibration will be required to ensure the sensors are
accurately detecting gas levels. If you are unable to perform a calibration and are in a
clean atmosphere, you can zero your sensors to reset the baseline.
SENSOR ERROR
When does G7 trigger a sensor error yellow warning alarm?
If a gas sensor stops working for any reason, G7 will inform you with a yellow warning
alarm. An X on your LCD screen will indicate which sensor or sensors are generating the
error message. Power o and restart your G7. If the sensor error warning persists, perform
a calibration. If this does not correct the problem, you will need to replace your cartridge.
CALIBRATION
When does G7 trigger a calibration yellow warning alarm?
When gas sensors are due for a calibration, G7 will inform you with a yellow warning alarm.
BUMP TEST
When does G7 trigger a bump test yellow warning alarm?
When gas sensors are due for a bump test, G7 will inform you with a yellow warning alarm.
PUMP BLOCK
When does G7 trigger a pump block yellow warning alarm?
If your pump inlet is blocked, G7 will inform you with a yellow warning alarm.
What do I do in the case of a yellow warning alarm?
Read your G7 screen. Press and hold the
up and down arrow buttons at the same
time to let your G7 know you have read
the message.
Yellow warning alarms are between
you and G7, and will not notify
monitoring personnel if you are
using real-time features.
G7 TECHNICAL USER MANUAL || 21
RED ALERT GAS FEATURES
Rapid Blinking
HIGH ALERT FOR GAS
When does G7 trigger a high alert for gas?
If a gas sensor detects gas levels above the high gas concentration threshold congured by
your safety supervisor.
NOTE: A G7 with O
enriched situations.
sensors will trigger red alerts in both oxygen-decient and oxygen-
2
STEL SHORT TERM EXPOSURE LIMIT ALERT
When does G7 trigger a STEL alert?
If a gas sensor detects you have reached the short-term exposure limit configured by
your safety supervisor. This limit is the gas concentration that you can be continuously
exposed to for a 15-minute time frame without suffering adverse health effects.
22 || G7 TECHNICAL USER MANUAL
TWA TIME WEIGHTED AVERAGE ALERT
When does G7 trigger a TWA alert?
If a toxic sensor detects you have exceeded the average allowable amount of gas during
an eight-hour period.
NOTE: The two TWA measuring methods available for use on your G7 are:
OSHA (United States Department of Labor Occupational Safety and Health Administration)
or ACGIH (American Conference of Governmental Industrial Hygienists).
OSHA is defined as a rolling average of gas exposure accumulated over an eight-hour
period of operation. If the worker is in the field longer, the most recent eight-hour
cumulative value is used.
ACGIH is dened as the total accumulated average, from four to 16 hours as congured
by your safety supervisor.
OL OVER LIMIT ALERT
When does G7 trigger an OL alert?
If a gas sensor detects an excessive amount of gas and can no longer give you an
accurate reading.
NOTE: STEL, LEL and peak readings are reset on power cycle unless configured to
resume readings in G7’s configuration profile in Blackline Live.
What do I do in the case of a red alert?
Evacuate the area and follow your
emergency safety protocol. Read the
information on your G7 screen. Press and
hold the up and down arrow buttons at the
same time to mute the sound and vibration.
The sound and vibration will return after one
minute. This will continue until gas levels
or averages have reduced or returned to
acceptable concentrations.
For real-time users, red alerts are immediately
communicated to monitoring personnel.
Muting sound and vibration does not cancel
the remote alert sent to monitoring personnel.
G7 TECHNICAL USER MANUAL || 23
CONFIGURATION MODES
Conguration modes are customized in the G7 conguration prole on Blackline Live. Each
prole supports up to a total of ve ‘modes’ . These modes allow G7 to temporarily change
its behavior for dierent situations, and can be turned on and o through G7’s interface.
AVAILABLE MODES
Normal
This mode is the configuration you determine for everyday operation. G7 will operate
using this mode as a default.
Pre-entry
Pre-entry mode is used before entering a space that could potentially contain
dangerous gas. This mode can be used with or without a pump cartridge, which will
actively draw surrounding air to its sensors and test gas levels.
SCBA
This mode is meant to be used when the device user is wearing a self-contained or
supplied air breathing apparatus (SCBA/SABA) and is entering an area that is known to
have high gas levels.
Leak check
Leak check mode can be used when checking for gas leaks in a particular area. This
mode – like pre-entry mode – can be used with or without a pump cartridge.
High risk
This mode is unique in that it is meant for general high-risk situations, such as an
evacuation or travelling through a dangerous area. Unlike the other modes, you will
never be timed out and must exit it manually.
Pump run
This mode is unique in that a multi-gas pump cartridge is required to use this mode, and
it runs the pump continuously – such as for use in a hole-watch situation. Unlike
the other modes, you will never be timed out and must exit it manually.
ENTERING A MODE

CARTRIDGE CARE
Sensor contaminants
Gas sensors are susceptible to contamination by a variety of common chemicals,
reducing or eliminating their sensitivity. Care should be taken when using silicones,
cleaners, solvents and lubricants in close proximity to sensors as exposure may
cause permanent damage to the sensor. If a device is exposed to a new chemical or
compound, it is best practice to bump test and calibrate units to ensure proper sensor
function is maintained.
LEL SENSOR PRECAUTIONS
For safety reasons this equipment must be operated and serviced by qualied personnel
only. Read and understand instruction manual completely before operating or servicing.
With pellistor technology (LEL-P), any rapid up-scale reading followed by declining
or erratic reading may indicate a gas concentration beyond upper scale limit which
may be hazardous.
High o-scale readings may indicate an explosive concentration.
Calibrations must only be performed in areas free of ammable gasses.
Blackline’s NDIR sensor does not detect Hydrogen or Acetylene. Like any gas sensor,
please be sure you understand your potential explosive hazards and choose the
appropriate sensor technology based on these hazards.
Blackline’s LEL-MPS sensor does not require calibration.

MULTIGAS PUMP CARTRIDGE
USING PUMP
How do I turn pump on?
1. Ensure G7 is equipped with a multi-pump cartridge
and pumped modes, such as pre-entry, leak check
or pump run
2. From G7’s main or secondary menu, select the
pumped mode you wish to enter
3. Attach tubing, and perform a block test by
following the instructions on G7’s screen
4. G7’s screen will invert, and the pump icon will show
in the info bar to let you know pump is running
How do I turn pump o?
To turn pump off, enter any non-pumped mode, such as
normal, SCBA or high risk mode.
Where do I see my pump details?
When a pump cartridge is attached to G7, you can see the pump status screen by
pressing the up or down arrow from G7’s main screen. Here you can see if pump is on or
o, your hose length, ow rate and sample time (if enabled).
How do I bump test or calibrate my pumped cartridge?
Manually bump testing and calibrating pump cartridges is done using the same
calibration cap and method as G7’s multi-gas cartridge. Please refer to page 14-16 of this
manual for step-by-step instructions. G7 cannot be bump tested or calibrated through
the pump itself.
Bump testing and calibrating with a G7 Dock requires an updated G7 Dock unit. You can
tell if your Dock is an updated unit by checking that it’s unit ID is Dock-P.
Pump on
Hose L: 5m
~300 ml/min.
Sample 75 sec.

How do I perform a block test?
You will be asked to perform a block test upon entering any pumped mode, such as leak
check, pre-entry or pump run. Follow the steps on G7’s screen to complete the block
test. If you do not pass the block test, you will not be able to enter the mode.
IMPORTANT: When performing an automatic block test, G7 is in a safe mode where gas
alerts will not be triggered. This prevents triggering false alerts from residual gas in the
tubing.
When you are in a pumped mode, you can perform a manual block test at any time by
plugging G7’s inlet. This will cause G7 to go into yellow warning alarm, and your screen
will let you know that your pump is blocked. Unplug your inlet, and if the warning alarm
silences, you know that your equipment is safe to use.
28 || G7 TECHNICAL USER MANUAL
What is ow rate?
Flow rate is the speed at which air is passing over your device’s sensors. In order to
provide accurate gas readings, ow rate needs to be above 150 ml/min. A ow rate less
than 150 ml/min will result in a pump block yellow warning alarm. By default, Blackline’s
pump aims to maintain a ow rate of 300ml/min and G7 will automatically adjust its
pump speed to maintain this rate.
PUMP OPTIONS
Settings for pump can be found in G7’s main menu, under settings > pump options.
What is the sample timer?
The sample timer is the amount of time it takes for one air sample to be pumped to
your sensors. This calculation is based on your hose length. If sample timer is enabled,
the pump status screen will show a countdown and beep once when a sample cycle
has completed. The sample cycle will repeat continuously until you turn pump o. If
disabled, the sample timer will not show and the device will not beep, and pump will
continue to function normally. Blackline recommends a 120 second sample time for 10
feet of tubing, with an additional second per foot of tubing.
How do I enable or disable the sample timer?
1. Press OK to enter G7’s main menu
2. Use the up and down arrows to navigate to settings, press OK
3. Use the up and down arrows to navigate to pump options, press OK
4. The menu will display the current status of your sample timer. Select
sample timer o or sample timer on.
5. Select yes to conrm that you would like to enable or disable the sample timer
What is hose length?
Hose length is an estimate of how long the tubing attached to pump is. This value is
customizable from the pump options menu, and factors in to sample time. G7’s multigas pump cartridge supports a maximum of 99 feet of tubing.
How do I change hose length?
1. Press OK to enter G7’s main menu
2. Use the up and down arrows to navigate to settings and press OK
3. Use the up and down arrows to navigate to pump options and press OK
4. Select hose length
5. Use the up and down arrows to choose your units, meters or feet, and press OK
6. Use the up and down arrow to enter the first digit of your length and press OK
7. Use the up and down arrow to enter the second digit of your length and press OK
8. Select yes to confirm your length or select edit to make changes to your choice
