What action should a central station take upon receiving trouble signals?

When a central station receives trouble signals, the appropriate action is to communicate immediately with the person in charge. This step is essential because trouble signals indicate issues such as system malfunctions, disconnection of signals, or other operational problems that do not necessarily require immediate emergency response but need to be addressed promptly.

By contacting the person in charge, the central station is able to gather more information about the situation. This communication can help confirm whether there is a legitimate issue that requires further investigation or if it is a false alarm. It also allows the person in charge to decide on the next steps based on their knowledge of the site's specific circumstances, ensuring a coordinated response.

Taking immediate action to communicate can prevent unnecessary dispatches of emergency services and can help in troubleshooting the issue effectively. Ignoring the signal could lead to overlooking a significant problem, and turning off the alarm system might exacerbate any underlying threats or issues. Therefore, establishing communication is a critical first step in managing trouble signals effectively.
