20、s for Electrical Equipment, Non-environmental Considerations1.2 SYSTEM DESCRIPTION*NOTE: This guide specification covers the requirements for three different types of intercommunication systems, one of which shall be selected for the project. The various types are as follows:Type 1, Direct Connected
21、, Keyed System. This type of system is applicable for relatively small systems (maximum quantity of remote stations approximately 30) and generally when only a small number of master stations (usually 1 or 2) are required. However, if there is a requirement for annunciation at more than one location
22、 or a requirement for multiple conversation paths, the use of this system with more than 1 or 2 master stations, or with many more than 30 remote stations may be justified or required.Type 2, Single Conversation Path, Central Control System. This type of system is applicable to relatively large syst
23、ems (more than approximately 30 stations) where only one conversation path is required and usually only one master station. This type of system is applicable to BEQs. This type of system includes public address and paging systems when the unique requirements are included.Type 3, Multiple Conversatio
24、n Paths, Central Control System. This type of system is applicable to various size systems where a large portion of the total quantity of stations are master stations. A limited quantity of conversation paths may be specified as required.*Provide an Intercommunication System, Data Package 3 in accor
25、dance with Section 01 78 23 OPERATION AND MAINTENANCE DATA, which is solid state, modular in design, and of the wired and wireless type as indicated. Stations shall have capacity for later expansion to _ master and _ remote stations with _ handset and or with hands free operation without sacrificing
26、 any equipment or feature of performance. When both wired and wireless circuitry are used, such interface shall not present a reduction of function or quality.1.2.1 Sound ReproductionProvide an intercommunication system to reproduce a signal at all receiving stations from a 40 dB minimum input signa
27、l referenced to a microphone sound pressure level (SPL) over the frequency range of 300 _ to 3300 _ Hz. The received signal shall have a dynamic range of 30 dB, adjustable at the receiving station. Unless otherwise specified SPL shall be 20 micro Paschal. The root-mean-square (rms) extraneous noise
28、(e.g. hum) level introduced by the intercommunication system shall be at least 30 _ dB below the nominal signal level. Distortion, including SECTION 27 51 23.10 Page 5Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-envelope delay, intermodulation, cr
29、oss talk, and other nonlinear sources, shall not exceed 5 percent.1.2.2 System Operation and Service Features1.2.2.1 Control and Power RequirementsProvide a system with a power switch and an associated pilot light for ON and OFF operations. USE a volume control at each station to regulate listening
30、volume. System shall operate on 110-125 Vac, single phase, 60 Hz.1.2.2.2 Call-In IndicationMaster stations shall have a “call-in“ switch to provide an audible and/or visual indication of incoming calls from remote stations. Individual visual indication shall identify calling station and status, and
31、remain actuated until a call is answered by a master station.1.2.2.3 Identification PlatesIn addition to the manufacturers standard identification plates, provide engraved laminated phenolic identification plates for each component connection and terminal. Identification labels shall be 3-layer blac
32、k on white on black, engraved to show white letters on a black background. Any warning or caution labels shall be 3-layered red on white on red, engraved to show white letters on red background. Control switches and knobs shall be clearly marked with their function and status. Identification strips
33、for station selector switches shall be located to clearly identify remote and master stations and shall be protected by transparent plastic inserts.1.2.2.4 Speaker/Handset StationsAt speaker/handset stations, lifting the handset shall automatically cut out the loudspeaker in the station and all conv
34、ersation shall be carried through the handset.1.2.2.5 Privacy Switch*NOTE: Where noise does not exceed 55 dB, specify hands-free operation from distances up to 6 m (20 feet). In areas where the noise occasionally exceeds 55 dB, a talk-listen switch which overrides the hands-free operation should be
35、specified. Where a high noise environment exists, delete hands-free operation and specify only a talk-listen switch.*Provide a privacy switch at each remote station. When in the ON position, the switch shall prevent any transmission of sound from the remote station. When in the OFF position, without
36、 further switch manipulation, the station shall respond to incoming calls upon voice activation from anywhere within a 6 m 20 foot radius of station.1.3 SUBMITTALS*NOTE: Review submittal description (SD) definitions in Section 01 33 00 SUBMITTAL PROCEDURES and edit SECTION 27 51 23.10 Page 6Provided

Submittals should be kept to the minimum required for adequate quality control.A “G” following a submittal item indicates that the sub
38、mittal requires Government approval. Some submittals are already marked with a “G”. Only delete an existing “G” if the submittal item is not complex and can be reviewed through the Contractors Quality Control system. Only add a “G” if the submittal is sufficiently important or complex in context of
39、the project.For submittals requiring Government approval on Army projects, a code of up to three characters within the submittal tags may be used following the “G“ designation to indicate the approving authority. Codes for Army projects using the Resident Management System (RMS) are: “AE“ for Archit
