What mode routes circuit power to the selected station for release once the appropriate switch is depressed?

• A. Automatic mode
• B. Standby mode
• C. Manual mode
• D. Selective mode

Answer: (D)

Selective mode is the way to route power to a single, chosen release point. In this mode, a selector determines which station will receive the energizing path, and when you depress the release switch, the circuit is completed only to that selected station. This gives precise control, ensuring that only the intended station is energized for release. Automatic mode would energize stations according to a preset logic, potentially affecting multiple or alternative stations without a single, explicit selection. Standby mode holds power in reserve and doesn’t route it to a release path, so no release occurs. Manual mode requires separate, direct control for each station rather than selecting one station to energize from a central control.
