[Adopted by Ord. No. 1461 (Sec. 4.12 of the Codification)]
To provide early warning in the event of fire, detection systems
shall be installed and maintained in operable condition in all occupancies
and locations set forth in this article.
[Amended by Ord. No. 1681]
Smoke and heat detection systems shall be installed in all spaces
in all new buildings regardless of size or construction except for
one- and two-family dwellings. The detection systems shall be in all
spaces, including, but not limited to, hidden spaces (e.g., attics,
crawl spaces, truss-constructed areas), basements, store rooms, closets,
occupied and unoccupied areas. One- and two-family dwellings shall
have smoke detection systems as required by the Wisconsin Statutes
and the Wisconsin Administrative Code. The Fire Department is authorized
to modify any of the provisions of this chapter upon application by
the owner, lessee, or a duly authorized representative where there
are practical difficulties in the way of carrying out the provisions
of the chapter, provided that the intent of the chapter shall be complied
with, public safety secured, and substantial justice done.
All detection systems shall be monitored by an approved off-site
central station monitoring service, except for one- and two-family
dwellings.
A.
All components of a fire or smoke detector system shall be listed
by Underwriters Laboratories (UL) or the Factory Mutual System (FM).
The entire installation shall conform to applicable provisions of
NFPA Standards 71, 72A, 72C, 72D or 72E, the National Electrical Code
Article 760, and the Wisconsin Electric Code.
B.
The system shall monitor the integrity of all alarm initiating and
indicating appliance circuits, shall be provided with automatically
charged standby batteries to maintain system operation for 24 hours
in the normal supervisory mode and have sufficient capacity to operate
in the alarm mode for five minutes at the conclusion of this supervisory
time period. Batteries shall be supervised for connection to the system
and for a low voltage threshold. The automatic battery charger shall
be capable of charging fully discharged system batteries at 100%.
C.
A Remote Annunciator shall be provided at the main entrance of the
building to indicate each of the designated alarm initiating zones
via red LEDs which flash when in alarm and lock in upon acknowledging
the alarm. The Remote Annunciator shall be electrically supervised
from the main fire alarm control panel. Space shall be provided on
the Remote Annunciator for custom zone labels. The zone labels shall
plainly describe the location of the zones. Different occupancies
in one building shall be zoned separately.
D.
Wiring of required fire and smoke detection systems.
(1)
All electrical wiring in connection with required fire alarm systems,
including accessory devices, such as detectors, shall be installed
in rigid metal conduit or surface metal raceway.
(2)
Separate raceway. Raceways for required fire alarm system wiring
shall contain no other circuits. All such raceways shall be colored
red.
E.
External devices.
(1)
The system shall utilize UL or FM listed fire alarm-initiating devices
(pull stations, smoke detectors, heat detectors, water flow switches,
duct detectors, etc.) and UL or FM listed fire alarm indicating devices
(horns, bells, visual lights, etc.). Smoke detectors shall possess
a light-emitting diode (LED) lamp to indicate "ready" or "alarm" status.
(2)
Smoke detectors (photoelectric, ionization) shall be installed approximately
30 feet on center, located on the ceiling or wall of the protected
area. Smoke detection shall be provided but not limited to the following
areas: basements, common hallways, stairwells, sleeping rooms and
all other rooms over 50 square feet in size.
(3)
Heat detectors shall be installed approximately 50 feet on center,
located on the ceiling of the protected area. Heat detection shall
be provided but not limited to the following areas: furnace rooms,
engine rooms, garages, hidden spaces and kitchens and all other rooms
under 50 square feet in area. Heat detectors shall also be installed
as a substitution for smoke detectors in locations determined by the
Fire Chief to be unsuitable for smoke detector installation.
(4)
Horns/bells.
(a)
Alarm system horns. Horns used as the audible alarm indicating
appliance shall be 24-volt direct current (DC) horns of metal construction
with a minimum sound pressure output of 87 db at 10 feet. Fire alarm
horns shall be UL or FM listed for fire alarm use. Horns shall be
adaptable for surface or semi-flush mounting and be suitable for use
within combination audiovisual systems.
(b)
Alarm system bells. Bells used as the audible-alarm-indicating
appliance shall be 24-volt DC bells of the vibrating or single-stroke
type with a minimum sound pressure output of 90 db at 10 feet. Bells
shall be UL or FM listed for fire alarm use. Bells shall be suitable
for surface or semi-flush mounting and be suitable for use within
combination audiovisual systems.
(c)
Visual flashing lamps. Visual indicating appliances shall be
comprised of a strobe-type flash tube and be entirely solid state.
These devices shall be UL or FM listed and be capable of either ceiling
or wall mounting. Visual units shall incorporate a built-in reflector
to improve lighting characteristics. Visual units shall be incorporated
as part of the horn or bell assemble.
(d)
Horns, bells, or visual flashing lamps shall be installed in
each unit, living space or tenant space in the building.
A.
Alarm-initiating devices shall be grouped in zones identified by
zone LEDs on the control panel and at the remote annunciator.
B.
Actuation of an alarm initiating device shall:
(1)
Cause the respective red zone alarm LED on the control panel to flash
until the "acknowledge" switch is actuated at the control panel. Once
acknowledged, the zone LED shall be constantly illuminated until the
actuating device is restored to normal and the system is reset or
equivalent operation.
(2)
The audible system indicating appliance shall sound through the entire
facility until the system alarm acknowledge/silence switch is operated.
(3)
Visual indicating appliances shall flash until the acknowledge/silence
switch is operated.
(4)
After the acknowledge switch is operated, subsequent activation of
an initiating appliance shall cause the alarm bells or horns to resound
and the visual indicating appliances to flash.
C.
Each alarm circuit and indicating appliance circuit shall be electrically
supervised. Any disarrangement of system wiring such as opens or grounds
shall activate the audible and visual trouble indicators at the control
panel. Actuation of the trouble silence switch shall silence the audible
trouble indicator but the trouble LED shall remain lit. The trouble
LED shall be noncanceling, except by an actual clearing of the trouble
condition and restoring the trouble silence switch to normal.
D.
The alarm system shall provide for the selection of:
E.
Upon actuation of smoke detector, the LED on the smoke detector shall
remain constantly illuminated until the system is reset.
No fire and smoke detection system shall be installed or altered
in any building until plans have been submitted to and conditionally
approved by the Building Inspector and the Fire Department. Two copies
of the plans shall be submitted. The plans shall contain drawings
showing locations of detectors, pull stations and horns. The plans
shall contain a brief description of connections within the system.
A.
The acceptance test of a fire and smoke detection system shall be
conducted in the presence of an inspector from the Fire Department
prior to being placed in service. All testing shall be conducted by
the installer.
B.
The installer shall give three working days' advanced notice to the
Fire Department prior to the conduction of any test.
Any fire alarm system which has been installed pursuant to this
section or in compliance with any other statute, ordinance or regulation
shall be maintained in operative condition at all time. It shall be
unlawful for any owner or occupant to reduce the effectiveness of
the protection so required; provided, however, that the owner or occupant
may temporarily reduce or discontinue the protection where necessary
to make tests, repairs, alterations or additions to the system or
appliance. The Fire Chief shall be notified before any system is reduced
or discontinued for such repair, alteration or addition and shall
be notified promptly upon the system's restoration to service.
