G7 c/x


Gone are the days of traditional gas detectors that functioned like smoke alarms, notifying only the wearer and those in earshot of a dangerous environment. Meet G7c/x — the world’s first 3G-connected gas detector with integrated lone worker monitoring and evacuation management tools. In the event of an emergency, G7c/x (c – cellular; x – satellite) wirelessly connects your team members with live monitoring personnel to mobilize and manage the fastest possible emergency responses.

Not just a gas detector — complete, real-time situational awareness

Technology that automatically watches over team members and calls for help, even when the employee can’t. Potential fall and no-motion events automatically trigger a pending alarm, asking you to confirm that you are OK — G7c/x will escalate pending alarms to alerts — these alerts are then communicated to monitoring personnel. G7c/x’s red SOS latch lets you manually trigger a call for help when assistance is required, automatically connecting you to a monitoring team.

Continuing to revolutionize gas detection

Blackline Safety is the world’s first gas detector and lone worker monitor to include a NEW push-to-talk service option that allows G7c to function as a two-way radio. G7c users will have the option to immediately call teammates on the same channel or to switch channels to easily communicate with other teams. Unlike conventional radios, push-to-talk (PTT) has no radio licensing and no range limit. PTT provides an organization with radio functionality without the need to invest in a separate fleet of radios. It combines a world-leading gas detector, a lone worker safety monitor and a two-way radio.
