A fire alarm system is number of devices working together to detect and alert people through visual and audio appliances when smoke/fire is present. These alarms may be activated from smoke detectors, and heat detectors.
Fire Alarm Initiating Devices
These devices inform the safety system that an incident is underway It can be alerted and safeguards can initiate. Since people are among the best fire detectors, these components include manual initiators, like alarm buttons, pull stations, and similar methods typically placed near exits.
Fire Alarm Notification Devices
These components inform people when all is well, when an event is underway, and when a maintenance issue is detected. Indicators can alert people in the building and at remote locations, including emergency responders, to an issue.
Fire Alarm Control Panel
The fire alarm control panel is the central brain which monitors and manages all of the initiating devices and sends signals to indicating devices if an issue is detected. The control panel typically contains standard branch-circuit writing and replaceable circuit cards.
