2.6.2 Power Module

The power module distributes the G1 SCBA power and provides all of the information for the control
module, regulator, and speaker module.
The power module is connected to the backplate. The power module connects to the alkaline or
rechargeable battery module, emits audible PASS alarms and pre-alarms, and has four buddy lights.
The power module has the following features:
• Rapid Intervention Team (RIT) light that comes on when a low-pressure alarm (configurable to
medium-pressure alarms) occurs to make it easier to see the UAC in the dark.
• Data-logging function that records information about the SCBA while the control module is turned
on.
• Internal real-time clock that is automatically set to UTC (Coordinated Universal Time) to download
logs and show time based on PC settings.
• Radio transmitter for telemetry module, if applicable

contains six replaceable, alkaline, C-cell batteries. The rechargeable battery module contains non

LED flashes on the HUD.
