? Standards: NFPA 13 (not NFPA 13R), 14 and 20.
? Water Source: Perform flow-test(s) and document. Provide dependable source of water quantity and pressure from municipal water main or from on-site cistern or tank(s) if municipal water is not available. ? Safety Factor: Provide a 10% hydraulic safety factor. ? Pressure Reducing Valves: Design system within maximum pressure of 175 psi without use of pressure reducing valves.

High Rise Buildings: Connect guestroom floor sprinkler piping to 2 risers at each floor with a control valve and flow and tamper switches at each connection. See example \test drain assembly detail at end of this Module. At guestroom and non-guestroom levels, locate inspector test assembly at remote end of zone, hardpiped to exterior similar to low-rise building.
2. System Application: Equip Marriott properties with
complete hydraulically designed combination / automatic sprinkler / standpipe system zoned by floor.

? Closets and Pantries: Sprinklers are not required in
clothes closets, linen closets and pantries within hotel guestrooms where the area of the space does not exceed 2.2 m2 (24 sq. ft.). Closets and pantries with washer, dryer, water heater, mechanical or electrical equipment require sprinklers.
? Building Exception: Sprinkler / standpipe system may not
be required in existing buildings of 2 stories or less where all guestrooms exit directly to exterior (no enclosed corridors).
3. Wet-Pipe Sprinkler: Provide wet-pipe sprinklers for
habitable spaces such as guestrooms, guestroom corridors, restaurants, ballrooms / meeting rooms, public and back-of-house areas. 4. Dry-Pipe Sprinklers: Provide dry-pipe sprinklers in attic and
unheated areas to avoid the possibility of freezing.
? Dry type heads from the wet system may be used in
small unheated areas.
? Wet sprinkler piping covered with attic insulation, pipe
insulation or heat tape is not considered “freeze protected” and is unacceptable. ? Use galvanized steel pipe.
? Design for dry valve trip test that provides water to the
remote inspector test assembly within 60 seconds.
? Provide system with valve, trim, tank mounted
compressor, control and test valves, gauges, pressure and high / low air pressure switches and approved drains.
5. Sprinkler Heads: Fast-response 68° to 74° C (155° to
165° F), recessed, semi-recessed and concealed throughout, except where listed for a particular application as follows:

6. Sprinkler Coordination:
? Install sprinkler heads with the manufacturer’s minimum allowable projection from the wall or ceiling. ? Coordinate locations of sprinkler heads at guestrooms and public areas with the interior designer to avoid location conflicts and minimize appearance impact. ? In corridor ceilings, generally, position heads along centerline of corridor width.
? In ceilings with acoustical tiles, position heads in center of tiles. G. Fire Alarm and Communications
1. Requirements: Equip entire building with a central fire
alarm system. See the Fire Alarm System Sequence Matrix in this Module. Coordinate with <15C>. ? Standard: NFPA 72.
? System: Provide fully point addressable, analog system (all alarm initiating and supervisory devices individually addressable) in all buildings. ? Campus Style Sites: Provide point addressable networking that reports to the continuously attended property location.
? Testing: Provide the following at the Fire Alarm Control Panel (FACP).
+ Disconnect switches to disable notification, audible
appliances, visual strobes, and auxiliary function points for testing purposes.
+ Alarm sensitivity testing at FACP.
