What is the purpose of trouble alarms in a fire detection system?

Trouble alarms play a critical role in fire detection systems by signaling when there is a problem within the system. This could involve issues like a malfunctioning sensor, a power failure, or issues with the wiring or communication between components. By alerting personnel to these problems, trouble alarms ensure that the fire detection system is maintained in optimal working condition, thereby allowing for timely repairs or maintenance. This proactive approach helps to enhance the overall safety of the facility by ensuring that the system will function correctly when needed.

While system readiness and fire detection features are important elements of fire safety, they serve different purposes from what a trouble alarm indicates. The activation during an actual fire incident is different from the purpose of a trouble alarm, which is solely to notify of system faults rather than fires or readiness status. Additionally, the automatic release of an extinguishing agent is a separate function that occurs in response to a fire, not in response to a malfunction or problem within the system itself.
