An annunciator panel fire alarm is a device used to detect and alert people of the presence of smoke or fire. It usually consists of an illuminated panel with several lights that correspond to specific devices, such as heat detectors, smoke detectors, manual pull stations, horns, and bells. When one of these devices detects a fire, it signals the annunciator panel which in turn activates the appropriate audible and/or visual alarms. This gives people more time to respond to the threat and allows personnel to identify the source of the danger quickly. Annunciator panels are essential components of any comprehensive fire safety system and are designed to provide clear warning of a potential emergency.
