What is mandatory before taking a fire alarm system "off-line"?

Notifying the monitoring company is crucial before taking a fire alarm system off-line as it ensures that those monitoring the system are aware that it will not be operational for a certain period. This communication helps prevent unnecessary responses from emergency services, which might be dispatched if the system fails to report alarms during that time. Proper notification allows the monitoring company to take appropriate actions, such as adjusting their protocols or informing relevant stakeholders about the status of the fire alarm system.

While resetting the system, disabling the alarm, and conducting a test are important steps at various times during the maintenance and operation of a fire alarm system, they do not specifically address the need for communication with the monitoring company regarding the system being off-line. Each of those actions may be part of the maintenance process, but they do not fulfill the critical requirement of informing the monitoring service that the system is temporarily inactive.
