SAFETY MONITORING FEATURES Your G7 is equipped with many features to monitor your safety. They are categorized into the type of notifications they trigger — yellow pending alarms, yellow warning alarms, and red alerts. All are customizable in Blackline Live to best fit your needs. Speak to your safety supervisor to learn about how your G7 features are configured.
POTENTIAL NO-MOTION DETECTED What is a potential no-motion detected? Your device is constantly monitoring your motion. It will automatically detect if you do not move within a pre-set duration, and will initiate a yellow pending alarm. The no-motion period and sensitivity are configurable. CHECK-IN REQUEST What is a check-in? If enabled, you can configure your device to request periodic check-ins throughout your shift. The check-in countdown is displayed at the top right of the LCD screen.
YELLOW WARNING ALARM FEATURES Rapid Blinking MESSAGES How do I receive a message? Your device can receive messages from monitoring personnel. When there is an incoming message, G7 will inform you with a yellow warning alarm. How do I send a message? You can choose from a list of 10 pre-programmed messages to send to monitoring personnel. The messages can be pre-programmed on Blackline Live.
SPEAKER PHONE How do I use two-way voice calling? If you have a G7c with a voice-enabled service plan, your speakerphone will automatically answer a call from monitoring personnel. G7 will inform you of an incoming call with a yellow warning alarm. The blue LiveResponse light will blink and you will hear a beep signifying the two-way voice call has been connected. In a noisy environment, it may be necessary to remove and hold the device near your ear, as you would a two-way radio.
RED ALERT FEATURES Rapid Blinking FALL DETECTED What is fall detected? If your device detects a fall and you have not responded to the yellow pending alarm, G7 will communicate a red alert to monitoring personnel. The fall detection sensitivity is configurable. NO-MOTION DETECTED What is no-motion detected? If you are not moving and you have not responded to the yellow pending alarm, G7 will communicate a red alert to monitoring personnel. The no-motion period and sensitivity are configurable.
MISSED CHECK-IN What is a missed check-in? If enabled and you are unable to check-in during the yellow pending alarm time, your device will communicate a red alert to monitoring personnel. SOS ALERT What is an SOS Alert? If you require assistance, you can manually send an SOS alert to monitoring personnel requesting immediate help to your location by pulling the red latch. NOTE: Your device can be configured to send a Silent SOS alert to monitoring personnel without light, sound and vibration.
GAS DETECTION Included with your G7 Single-gas or Quad-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, refer to the G7 Dock technical user manual.
Tubing Single-gas calibration cap Tubing Quad-gas calibration cap G7 TECHNICAL USER MANUAL || 25
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 0.
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 configured to automatically zero on start-up when you turn on your device in Blackline Live. NOTE: The baseline reading for oxygen is 20.9. How do I zero sensors? 1.
GAS DETECTION FEATURES Once you have completed the bump test and calibration, your 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 G7 gas features are configured.
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.
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 maximum gas concentration configured by your safety supervisor, G7 will communicate a red alert to monitoring personnel. NOTE: A G7 with O2 sensors will trigger red alerts in both oxygen-deficient and oxygenenriched situations.
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, G7 will communicate a red alert to monitoring personnel. 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).
CARTRIDGES GAS CARTRIDGE REPLACEMENT PROGRAM What do I do when I need a new gas cartridge? If you have an uninterrupted service plan for your G7 gas cartridge, Blackline will replace expired cartridges for you free of charge. To inquire about or request new cartridges, please contact our Customer Care team or your distributor. CHANGING CARTRIDGES How do I change my G7 cartridge? 1. Power off G7 2. Using a Torx T8 screwdriver, remove the screws on each side of the device 3. Pull up on the cartridge 4.
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.
FIRMWARE UPDATES OVER-THE-AIR (OTA) FIRMWARE UPDATES How does G7 get updated? To offer new features, Blackline Safety periodically releases over-the-air (OTA) firmware updates. Your G7 device will automatically download and install the new firmware. Blackline Safety will contact you directly for specific information about new updates.
