What should you do to silence the prealert signal in an alarm system?

To effectively silence the prealert signal in an alarm system, the action indicated by the correct response involves using the designated button that corresponds specifically to silencing alarms. In many alarm systems, different buttons are assigned for various functions, and the yellow button is often associated with silencing or canceling alert signals. Understanding the specific functionality assigned to each button is crucial in emergency situations to ensure safety and swift response.

The other options likely represent buttons that have different functions, such as activating alerts or performing other system commands, which is why they are not suitable for silencing the prealert signal. Being familiar with the functionality of each button in an alarm system can aid in efficient management during emergencies.
