10、 This revision of BS 4737 has been prepared under the direction of the Electronic Equipment Standards Committee to reflect the technical advances in the industry since the publication of the 1971 edition. It takes account of AmendmentNo. 1, 1972 (AMD 1064)and of Amendment No. 2, 1973 (AMD 1218). It
11、is being published in a number of separate Sections, as follows. Part 1: Requirements for systems with audible signalling only; Section 1.1: Installation; Section 1.2: Maintenance and records; Part 2: Requirements for systems with remote signalling; Section 2.1: Installation; Section 2.2: Maintenanc
12、e and records; Part 3: Requirements for detection devices, consisting of a number of separate Sections (3.1 to 3.14). The specifications for detection devices (including this Section of BS 4737) are to be read in conjunction with Section 1.1 or Section 2.1, as appropriate. A British Standard does no
13、t purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside f
14、ront cover, pages i and ii, pages 1 and 2, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on theinside front cover.BS 4737-3.10:1978 BSI 1998 1 1 Scope This British Sta
15、ndard specifies the general requirements for vibration detectors to be used in intruder alarm systems in buildings. 2 References The titles of the standards publications referred to in this standard are listed on the inside back cover. 3 Definition For the purposes of this British Standard, the foll
16、owing definition applies in addition to those given in BS 4737-1.1 and/or BS 4737-2.1. vibration detector a detection device designed to generate an alarm condition in response to vibration resulting from a physical attack on the structure to which the sensor is fitted 4 Performance The detector sha
17、ll be designed to distinguish between environmental vibrations and vibrations resulting from a physical attack which may be intended to penetrate the structure. The means for achieving this may be adjustable to suit varying circumstances. 5 Area of coverage The area of coverage of the detector is th
18、at area of the structure over which manual attack which may be intended to penetrate the structure, causes the detector to generate an alarm condition or to signal to a processing device. The installer shall identify the area of coverage in the equipment record (see 7.1 of BS 4737-2.2:1977) and shal
19、l also declare therein the type of attack which, occurring within the area, will cause the generation of an alarm. 6 Test period Except when immediate connection is needed for urgent security reasons, or when the detector replaces a similar existing unit, the detector shall not be connected to an al
20、arm system which is extended to the police until the detector has operated in the installation for at least 7 days without generating an unwanted alarm. 7 Power supply An alarm condition shall be generated if the voltage of the power supply to the detector is reduced sufficiently to impair the perfo
21、rmance of the detector. 8 Environment The requirements of this British Standard shall be met by the detector under any combination of the following environmental conditions. 9 Interference The detector shall be adequately protected against any externally-generated radio-frequency interference and/or
22、 mains-borne interference which may normally be expected to occur within the working environment. 10 Housing The sensor (unless it is mounted directly on to glass) and any processing device shall be housed in one or more containers. It shall not be possible to open the container(s) by the normal mea
23、ns of access without operating an anti-tamper device. If the equipment is housed in separate containers, the interconnection(s) shall be electrically protected. Any means for adjusting the equipment shall be enclosed within the container(s). Temperature: 0 C to 40 C Relative humidity: 10 % to 90 %2
