(Ord. No. 2013-94. Passed 6-19-95, eff. 6-28-95)
All interior fire alarm systems shall be supervised closed circuit electrically operated systems except that in specific instances, where deemed adequate for the purpose by the Division of Fire, manually operated trip fire gongs not less than eight (8) inches in diameter may be installed in buildings not more than two (2) stories in height, and except that open circuit systems may be installed in specific instances where deemed adequate for the purpose by the Division in buildings where noncoded systems are permitted by this Fire Prevention Code and where not more than two (2) alarm sending stations are required.
(Ord. No. 991-49. Passed 6-27-49, eff. 6-27-49)
As used in this Fire Prevention Code:
(a) “Interior fire alarm system” means an alarm system installed within a building and provided and intended to warn the occupants of the building in the event of fire by means of an audible signal transmitted from manual trip stations, signal stations or boxes, or automatic fire detecting devices.
(b) “Closed circuit system” means one in which all circuits between alarm sending stations, sounding devices and annunciators are maintained as normally closed electrical circuits.
(c) “Open circuit system” means one in which all circuits are maintained as electric circuits normally open at the alarm sending stations and which is operated by closing the circuit at any alarm sending station.
(d) “Coded closed circuit interior fire alarm, signal system” means interior fire alarm signal consisting of sending stations and signaling devices operated on supervised closed electrical circuits where rounds of automatically sounded coded signals are transmitted to indicate the floor or portion of the same from which the alarm was sent.
(e) “Noncoded closed circuit interior fire alarm signal system” means an interior fire alarm signal system consisting of sending stations and signaling devices operated on supervised closed electrical circuits so arranged that operation of any station will automatically sound the sounding devices throughout all portions of the building.
(f) “Presignal system” means a coded closed circuit interior fire alarm signal system so arranged that the operation of any station will cause the sounding of the sounding devices located at a main telephone switchboard, office, custodian’s room, chief engineer’s office or other place within a building, to notify a responsible person that an alarm box has been operated, and the location of such alarm box. Alarm stations of a presignal system shall be so equipped that operation of any alarm sending station by an authorized person in a special manner or by use of a special key shall cause the sounding of all sounding devices throughout the building.
(Ord. No. 991-49. Passed 6-27-49, eff. 6-27-49)
All required electrically operated interior fire alarm systems and all devices and equipment in connection with such fire alarm systems installed after June 27, 1949, shall be systems, devices and equipment of a type which has been approved for the purpose by the Board of Building Standards and Building Appeals. Systems, devices and equipment which have been tested and approved by the Underwriters’ Laboratories, Inc., or tested and approved by other recognized testing laboratory with adequate equipment, experience and competency, may be approved by the Board without additional tests.
(Ord. No. 991-49. Passed 6-27-49, eff. 6-27-49)
All required interior fire alarm systems shall be installed in conformity with plans therefor which have been submitted to and approved by the Fire Chief. Plans submitted for approval shall clearly describe all component parts of the proposed system and indicate, in diagrammatic fashion, the proposed location of all alarm sending stations, sounding devices and annunciators.
(Ord. No. 991-49. Passed 6-27-49, eff. 6-27-49)
