Office buildings are used for conducting business transactions. They are commonly characterized as low hazard occupancies, however; a designer may need further assessments because such buildings may involve certain rooms that contribute a higher hazard classification due to their occupants or contents. Commonly, office buildings are protected with sprinkler system, standpipe system and fire extinguishers as well as fire alarm system. Office buildings also include special hazard rooms that require protection by other types of systems. High rise office buildings increase the challenge of fire protection. In such buildings, the occupants are totally dependants on fixed fire protection systems. The time elapsed for evacuation in those buildings is relatively higher than other buildings. Hence, in such buildings mass notification and graphical representation of fire events is essential.
