T <br />b c" 46 <br />a <br />' <br />4 <br />r <br />4 i <br />(Fig. 6.4) Good diagram, with clearly organized and labeled <br />lamps, as well as building features to assist the fire service. <br />S4 <br />Consistent designations for any floor indications <br />used in the building will avoid confusion. For exam- <br />ple, it is imperative that floor designations on the <br />signs mounted in stairways, elevator cars, and ele- <br />vator lobbies, be consistent with the annunciator so <br />the firefighters report to the correct floor. <br />In addition to information about floors, zones, <br />and devices, many features of the building could be <br />shown on the diagram. These include fire protec- <br />tion systems and building components that the fire <br />department needs to be aware of (Figure 6.4). <br />Designers should remember that modifications <br />to the building or its layout may require changes to <br />the diagram. An annunciator with inaccurate infor- <br />mation could be worse than no annunciator at all. <br />Considerations - Graphic Displays <br />■ Include graphics to show location-related <br />information. <br />■ Include standard features required for the <br />jurisdiction. <br />■ Coordinate the orientation of the diagram <br />with its location in the building. <br />■ Provide separate sprinkler diagrams if zone <br />boundaries do not coincide with other alarm <br />devices. <br />■ Coordinate floor level designations. with ele- <br />vators and stairways. <br />■ Include the following building features: <br />o Building address; <br />o North direction arrow; <br />o Stairs, their identification, and the floors <br />they serve; <br />o Elevators, their identification, and the <br />floors they serve; <br />o Elevator machine rooms; <br />o Exterior entrances; <br />o Standpipe locations; <br />o Location of utility controls (electric, gas, <br />fuel); <br />o Fire alarm control panel; <br />o Fire pump(s); <br />o Fire department connection(s). <br />G%U <br />Occupational Safety and <br />Health Administration <br />170 <br />
