A fire alarm system is of the devices working together to detect the sign of fire in its early development and helps in reducing the loss to a great extent. The detection is made through audio and visual appliances when smoke, fire or carbon monoxide is present nearby. There are numerous ways to activate these alarms automatically from smoke detectors, heat detectors or via manual fire alarm activation.
Fire alarms deploy motorized bells, wall mounted sounders or horns to warn the people to take the preventive measures. A loud bell or a siren, sometimes accompanied by the blinking or flashing lights for individuals who have hearing problems, blasts to alert the occupants in the building.
