Gas Detection Modes
An overview of the configuration-based gas-detection modes for G8.
Configuration modes are customized in the G8 configuration profile in Blackline Live. Each profile supports up to a total of five modes. These modes allow G8 to temporarily change its behavior for different situations and can be turned on and off through G8's interface.
| Normal | Use this mode for everyday operation. G8 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 draws 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 must be exited 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 must be exited 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. Blackline Safety must turn on this feature for your company before it is available in your Blackline Live organization. For more information, please contact Blackline Safety's Technical Support team. |

If you select Yes, the mode remains active.

If you do not make a selection within 30 seconds, G8 automatically returns to normal operation. If you have a check-in timer enabled, G8 immediately prompts you to check in.
