A.
Alarm and Detection Systems
1.  Fire alarm systems are generally required for all buildings that are
occupied by 50 or more people or that are more than one story in height and as
required by NFPA 101.
2.  Fire alarm control panels (FACPs) shall be located just inside a main
building entrance in a visible, accessible location. Annunciation shall be
integral with the FACP.  The intent of this is to allow fire departments to
rapidly access control panels and pinpoint alarm location. Remote annunciation
may also be provided at designer's discretion.  Show location on drawings.
3.  When automatic detection is to be provided, plans shall include a
"TABLE" indicating the detector type, temperature rating, room locations,
etc. Do not show detector locations on plans or drawings.  (Contractors are
required to locate detectors in accordance with the performance provisions for
the specification).
4.  Manual pull stations shall be located at every exit. Show locations
on drawings.
5.  Audible and visual alarms shall be located throughout all corridors
and large open areas such as gymnasiums, open-plan offices, warehouses, shops,
stores, etc. Show locations on drawings.
6. Due to their extremely bad track record with the Navy, "multiplex"
systems are prohibited.
7. Radio or telegraphic master boxes shall be placed in accessible,
visible, and trafficked exterior locations. Show location on drawings.
8. When smoke detectors are provided, specify separate zones for
detectors and manual pull stations. Always specify a separate zone for
sprinkler water flow.
9.  Duct-type smoke detectors shall be provided in air handling systems in
accordance with the latest edition of NFPA 90A. Activation of detection shall
shut down air handling unit and sound building alarms.  Careful coordination
with mechanical specifications is mandatory.
10. Do not locate smoke detectors were subject to false alarms due to
hostile environments, etc. (e.g. dirty or corrosive atmospheres, unheated
spaces such as attics and crawl spaces, kitchens, toilet rooms, smoking
lounges, laundries, janitor's closets, mechanical rooms, etc.)
11. All concealed smoke detectors (blind spaces, underfloor areas, duct
detectors, etc.) shall be remotely annunciated.  Show annunciators on
drawings, and specify.
