Section 27-971

Section 27-971

  §  27-971  Classification  and  general  requirements  of  fire  alarm
systems.  Fire alarms shall be classified as follows and shall meet  the
following general requirements:
  (a)  Uncoded  closed circuit fire alarm system. Consisting of manually
operated sending stations and audible  signaling  devices,  so  arranged
that  the operation of any station will automatically sound continuously
the signaling devices throughout all portions of the building.
  (b) Master coded closed circuit  fire  alarm  systems.  Consisting  of
manually operated pull-lever type sending stations and audible signaling
devices,   so   arranged   that   the  operation  of  any  station  will
automatically sound the  signaling  devices  giving  a  common  code  of
signals  throughout all portions of the building. The code shall consist
of four rounds of a series of single strokes of the  signaling  devices,
each round consisting of "3-3-3-3".
  (c)  Individually  coded  closed  circuit  general fire alarm systems.
Consisting of manually operated pull-lever  type  sending  stations  and
audible signaling devices, so arranged that the operation of any station
will  automatically sound the signaling devices, throughout all portions
of the building, for a minimum of four rounds of a distinctive  code  of
signals  particular  to  the  station  at  which  the  signal  has  been
initiated. The code numbers that  are  used  shall  be  subject  to  the
approval of the fire commissioner.
  (d)  Individually  coded  closed circuit presignal fire alarm systems.
Consisting of manually operated pull-lever  type  sending  stations  and
signal  devices so arranged that the operation of any station will cause
the sound of only the signal devices located  in  the  engine  room  and
basement  and  other  places in the building where the members of a fire
brigade work or assemble. The signaling device shall give four rounds of
the particular code signal of the station at which the signal  has  been
initiated.  Approved equipment shall be provided at each station so that
the operation of any station performed with the aid of  a  key  or  plug
will  sound  all of the signal devices located in the building with four
rounds of the particular coded signal of the station initiated. The code
numbers used shall be subject to the approval of the fire  commissioner.
The  presignal  key  or plug shall be so designed that it can be readily
identified. Presignal type  systems  will  not  generally  be  approved;
however,  approval  may  be  obtained  from  the fire commissioner where
special type occupancies may warrant such a system.
  (e) Combination unit or zone, and general alarm coded  closed  circuit
fire  alarm  systems.  Consisting  of  manually operated pull-lever type
sending stations and signal devices so arranged that  the  operation  of
any station will cause all of the signaling devices in that unit or zone
to  sound  four  rounds  of  the  particular coded signal of the station
initiated, and simultaneously will cause all of the signaling devices on
the general alarm circuit to sound  four  rounds  of  the  coded  signal
designating  the  unit  or  zone  in  which  the  station is located. An
approved register and time stamp may be used  in  connection  with  this
system  when  approved by the fire commissioner. The register, if of the
closed circuit type, shall be operated from a  separate  closed  circuit
control board or panel isolated by a barrier from the main control panel
in  the main fire alarm control cabinet. An approved closed circuit unit
annunciator with trouble alarm circuit shall be  installed  as  part  of
this system when required by the fire commissioner.

supplemented by special circuits for the operation of other  fire  alarm
or  detection  devices  in  the systems, or electric control systems for
stopping machinery, closing doors or ventilators, or shutting down  fans
as  may  be  required  by  the  commissioner or the code, or to call the

central station of a private operating company of the  fire  department.
Automatic fire detecting systems may be connected to operate an interior
fire   alarm   system  when  connected  thereto  by  an  approved  coded
transmitter.  In  no case shall the transmitter be considered to replace
the standard approved  interior  fire  alarm  station,  except  where  a
transmitter  has  been  approved  for both purposes. The special control
circuits and devices shall be separate and distinct from the fire  alarm
system  but  shall be brought into action whenever the fire alarm system
is set in operation.
