Fire detection system uses detectors to detect smoke/heat to detect any fire occurrence. It provides warning to people through visual and audio alarm when smoke, fire or other emergencies are present. These alarms may be activated automatically from smoke detectors and heat detectors or may also be activated via manual fire alarm activation devices such as manual call points or pull stations. Alarms can be either motorized bells or wall mountable sounders or horns. They can also be speaker strobes which sound an alarm. Detectors send signal to fire alarm panel. The fire panel activates the alarm in sounders. The sounders can be set to certain frequencies and different tones including low, medium and high, depending on requirement.
