- Wrist worn transmitter: This device, worn by each crew member, monitors each person’s activity. The transmitter regularly reports each crew member’s code and power information to the identification reader in the same channel. The identification reader then transfers this data to the system service program and the information is logged by the system and available for display. The emergency help function of the transmitter will instantly emit a help needed signal in the event of an emergency and facilitate rescue.
- Man identification reader: This system is responsible for linking the monitored environmental domain information into a network which adds the monitored area code to the data received from each transmitter. This data is then transferred to the system service program which will determine the location of each crew member.
