What type of fire alarm system requires the FA contractor to attach a label documenting the type of service to the FACP?

The correct answer is the Central Station fire alarm system. In a Central Station system, the fire alarm signals are monitored at a central location, and it is essential for the fire alarm contractor to document the type of service provided. This documentation typically includes a label that outlines the specifics of the service, ensuring that all parties involved are aware of the system's capabilities and the monitoring parameters in place. This practice fosters accountability and provides a clear record of the system's service history.

In contrast, proprietary systems are generally monitored by in-house personnel and do not follow the same external documentation requirements. Local systems operate independently and do not require central monitoring, which eliminates the necessity for such labels. Remote station systems send alarms to an off-site monitoring location but, like local systems, they do not necessitate the same level of formal documentation regarding service types as found in Central Station systems. Thus, the requirement for labeling in a Central Station setup highlights the need for thorough tracking and assurance of service standards in more complex fire alarm monitoring environments.
