Heritage properties have cultural-historical or scholarly value. They also have financial value represented in a county`s revenue due the designation of such properties as tourism location. These properties are priceless as the ability to re-build such a property or re-produce any of the contents involved in it is extremely limited. Thus, an uncontrolled fire event in such a property may lead to severe cultural and economical losses. The installation of active fire suppression and alarm systems in such properties if applicable, is extremely important. Small areas in such properties are usually protected by clean agent fire extinguishing systems. If impractical, high pressure water mist system is an acceptable alternative. On the contrary, large areas in such proprieties are usually protected by pre-action sprinkler system to reduce the probability of false discharge. As for the detection optical smoke and heat detectors are usually used. Due to the large number of visitors whom are not familiar with such properties, the installation of mass notification systems is essential to reduce the losses in lives and properties during fire events.
