What is the maximum time allowed for trouble signals to display at the Fire Alarm Control Panel (FACP)?

The maximum time allowed for trouble signals to display at the Fire Alarm Control Panel (FACP) is established by relevant safety codes and standards. In the context of fire alarm systems, it is critical for trouble signals to be displayed in a timely manner to ensure that any issues affecting the system are promptly addressed.

The established standard specifies that trouble signals should remain active at the FACP for no longer than 200 seconds before they require either acknowledgment or reset by the operator or maintenance personnel. This 200-second timeframe ensures that operators are alerted to potential issues, such as device malfunctions or system faults, allowing for quicker response times and maintenance actions.

This protocol helps maintain the reliability and effectiveness of fire alarm systems, ensuring that they remain operational and capable of responding to emergencies without unnecessary delay. Understanding this time limit is crucial for anyone involved in the maintenance or operation of fire alarm systems, as it emphasizes the importance of timely response to trouble signals.
