Which signal requires the dispatcher to communicate that they are alone?

Signal 26 is utilized to indicate that an officer is alone and requires the dispatcher to acknowledge this status. This signal is crucial for ensuring the safety and security of officers working in potentially hazardous situations. By communicating that they are unaccompanied, officers alert dispatchers to the need for heightened awareness regarding their safety.

Understanding these signals and their specific usages is important for effective communication and coordination during operations, ensuring that all personnel are informed and able to respond appropriately in varied scenarios.
