Customized mass notification text messages or Push-To-Talk to individual G7 devices quickly lets workers, specific teams or entire sites know they need to evacuate and can direct them to muster points or other safe locations

G7 Dock Station
Unlike the complicated functions of other docking systems, G7 Dock is simple to use and ready right out of the box — all you have to do is plug it into an outlet. Once a gas cylinder is attached and a G7c or G7x wearable device is inserted and the lid closed, pending calibrations or bump tests are initiated and completed automatically. Device entirely compliant? Your G7 device can simply stay in the dock to charge for as long as needed.
