Shipboard common battery telephones are a type of communication system used on naval ships. They allow crew members to communicate with each other via telephone handsets that are connected through a central battery system. Some key points about shipboard commno battery phones: - They operate on low voltage DC power provided by central batteries, hence the name "battery phones." This allows them to work even if AC power is lost. - They form an independent communications network from the ship's main phone system. This provides redundancy in case of damage or system failure. - The phones can be wired in a "slave to master" configuration. This means secondary "slave" phones are connected to a primary "master" phone rather than directly to the battery. - In a "slave to master" setup, the "slave" phones will only work if the "master" phone is connected to the battery power. This allows for selective activation of phones. The "slave to master" terminology comes from the electrical engineering concept of a master device controlling subordinate slave devices. In this system, the master phone must be powered for the slave phones to work. The shipboard common battery phones give sailors a reliable emergency communications system that is independent of the ship's main power and telephone infrastructure. The "slave to master" wiring provides control over which stations are active.
