The FMAR Air Package provides the back-end system for air monitoring. For front-end systems that display this data, look at the "FMAR Air Gauge" and the "FMAR Air LED" packages.

FMAR Air data is networked from the client to the server, with the intention that air data is sourced from the client's local gear. This allows air data to be sent to other networked users for rapid alerts and notifications if there is any issue with a first responder's air supply. Some nofications are sent to all clients when air passses critical thresholds. If any user's air supply drops below 75%, 50%, 25%, or completely runs out at 0%, all other users are notified via the FMAR Notifications system, and can take appropriate action.
