33、.3 Class 1 8.tlstem.s. 3.3.3.1 Operation, The operation of any alarni initiating device, shall cause its code to soiincl on all alarm bells and other sound- ing devices in the system. 3,3.3.1.1. When so specified (see 6.1)? the system shall be provided with a feature to soiind a continuous alarm aft

34、er the selective coded alarm signal has been completed to provide an evacuation signal of longer dura- tion. 3.3.4 Clilas 2 sgstenzs. 3,3.4.1 peratoon. The operation of any alarni initiating device shall cause its code to soiincl only on the presignal bells. Pro- visioiie shall be made in each stati

35、on for soiiiicling c? general alarm by inserting a key or plug with a special shaped shank, partic- ularly iclentified for the purpose, into a key- hole or receptacle before operating the sts- tion. The key or plug, while inserted, shall be plainly visible or shall prevent the door, if so equipped,

36、from closing. When other jacks (telephone, etc.) are provided in the station, each jack shall be properly identi- fied to avoid confusion in operation, 3.3.4,.l When so specified (see 6J), the system shall be provided with a feature to 8oiind a continuous alarm after the selective coded alarm signai

37、 has been completed to provide an evacuation signal of longer dura- tion. 3.3.42 General alarm sudteh. When speci- fied in the invitation for bids, a switch shall bo provided at the control unit whereby any alami transmitted can be made to sound all alam bells and other signalling devices in the sys

38、tem, A red pilot Iarnp or other aiml at the control unit shall indicate when the switch is in the general-alarm position. When specified in the invitation for bids, additional signals indicating the position of the switch shall be furnished. 3.3.5 Stzjle A syatems. Style A systems shall consist enti

39、rely of manually operated stations and the necessary circuitry and hardware required for an efficient and in- tegrated system as hereinafter provided. 3.3.6 Stzjle B sijstems. Style B systems shall consist of both manually operated sta- tions and automatic fire detectors and trans- mitters for the p

40、rotection of both habitable and storage areas, Automatic detector trans- mitters shall provide a coded signal indicat- ing the area in which the actuated detector is located. 3.4 Stations. 3.4.1 General. Except as otherwise pro- vided herein, stations shall conform to the applicable requirements of

41、NEMA Stand- ard SB1-1962, Part 4, Section 1. 3.4.1.1 All stations shall be of the pull- lever type. The act of pulling the lever shall either wind an operating spring in the sta- tion mechanism which, when the lever is re- leased, shall drive the mechanism, or ener- gize an electric motor-driven dev

42、ice to sound at least four rounds of the code, The de- sign shall be such that after the lever has been pulled and released, it shall return to its3 initial position and either trip free from the mechanism or be locked in its initial po- sition so that it shall be impossible to inter- fere with or c

43、onfuse the signals by further manipulation of the lever, The arrange- ments shall be such that if the lever is not pulled all the way down, the station shall transmit at least a proportionate number of rounds, but in no case shall it transmit only a portion of a round, 3.4.2 Test faciZztzes. Means s

44、hall be pro- vided for testing the station mechanism without transmitting any fire alarm signal. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-W-F-37bC 42 W 9997974 001b4Bl b Provisions shall be made so that the system cannot be left inoperable wit

45、h the test key removed. When test keyhole is normally open to view, it shall not be possible to make the station inoperable by inserting and leav- ing a small object (not the test key) in the test keyhole. The construction of the test key feature shall be such that finger springs or other delicate p

46、arts cannot be put out of adjustment by undue forcing of the key. Means shall be provided for trans- mitting individual taps to all alarm bells without transmitting any fire alarm signal. 3.4.3 Constmction. 3.4.3.1 Class 3 stations. Class 3 stations shall be equipped with a glass plate or rod with b

47、reaking means secured to the sta- tion and so constructed that either pulling the pull lever will break the glass and actu- ate the station or that breaking the glass will provide access to the pull lever. Pro- vision shall be made for authorized person- nel to circumvent the glass breaking feature

48、to facilitate test and inspection procedures. 3.4.3.2 Style C stations. Stations designed for interior use shall have a cast metal or galvanized, bonderized or equivalent sheet- steel back box, shall be arranged for thread- ed metal conduit connections, or knockouts, at the top and bottom, and shall

49、 have an in- ner case of substantial protective metal, plastic or glass enclosing the mechanism, when applicable. Sheet-steel back boxes shall be of metal having a nominal thickness of No. 16 gauge. All openings into the inner enclosure shall be substantially dusttight. The mechanism shall be housed in a manner to permit easy access to the movement, by means of a special tool, so that it can be in- spected without disconnecting the station from its circuit or putting tension on the st
