A fire alarm system has a number of devices working together to detect and warn people through visual and audio appliances when smoke , fire , carbon monoxide 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.

Cultural property management is entrusted with the responsibility of protecting and preserving an institution's buildings, collections, operations and occupants. Constant attention is required to minimize adverse impact due to climate, pollution, theft, vandalism, insects, mold and fire.

Optical Smoke Detectors Intruding smoke activates an alarm in this detector. It is sensitive to smoke as it arises from smouldering fires even without flames. UV Flame Detectors Ultraviolet rays as from a flame will actuate an alarm in this detector. It is suitable for fires with only light smoke emission as from most burning liquids. Thermal Detectors A thermal detector is senitive to either a certain maximum temperature or a rate of rise of temperature.
