Configuring Gas Detection Modes
Configuration modes are customized in the G7 configuration profile in Blackline Live. Each profile supports up to a total of five modes. These modes allow G7 to temporarily change its behavior for different situations and can be turned on and off through G7’s interface.
Available gas detection modes include:
| Normal | Use this mode for everyday operation. G7 operates using this mode as a default. |
| Pre-entry | Activate this mode before entering a space that could potentially contain dangerous gas. Pre-entry mode can be used with or without a pump cartridge, which actively draw surrounding air to its sensors and test gas levels. |
| SCBA | Use this mode when you are wearing a self-contained or supplied air breathing apparatus (SCBA/SABA) and are entering an area that is known to have high-gas levels. |
| Leak check | Use this mode 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 | Use this mode for general high-risk situations, such as an evacuation or traveling through a dangerous area. High-risk mode allows devices to have more frequent check-ins and modified functional settings. Unlike the other modes, it never times out and you must exit it manually. |
| Pump run | Pump run mode requires a pump cartridge, and it runs the pump continuously – such as for use in a hole-watch situation. Unlike the other modes, it never times out and you must exit it manually. |
| Over LEL |
This mode lets you silence LEL alarms and alerts when you are entering a known high-gas environment. Over LEL mode must be activated prior to entering the high-gas environment and can be configured to time out after a specified period.
Note:
OVER LEL mode must be configured by your company’s Blackline Live administrator in Blackline Live. You cannot configure Over LEL mode on your device. For more information, contact your Blackline Live administrator. |
Some modes can be configured in Blackline Live so that they are only available when a pump cartridge is installed. To enter a mode that uses the pump, you must complete a successful pump block test.
Gas detection modes used in areas with potential gas (pre-entry, SCBA, leak check, and over LEL) have a timeout period. After the timeout interval elapses, G7 prompts you whether you would like to continue in this mode:
If you select Yes, the mode remains active.
If you select No, G7 returns to normal operation.
If you do not make a selection within 30 seconds, G7 automatically returns to normal operation. If you have a check-in timer enabled, G7 prompts you to check in.
