The work of preparing International Standards is normally
9、carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the wo
10、rk. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare Inte
11、rnational Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of t
12、he elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 7240-11 was prepared by Technical Committee ISO/TC 21, Equipment for fire protection and fire fighting, Subcommittee SC 3, Fire detection and alarm s
13、ystems. This second edition cancels and replaces the first edition (ISO 7240-11:2005), which has been technically revised. It also incorporates the Amendment ISO 7240-11:2005/Amd.1:2009.

20、rvedIntroduction This part of ISO 7240 has been prepared by ISO/TC 21/SC 3, the secretariat of which is held by SA and is based on ISO 7240-11:2005. This part of ISO 7240 has been drafted on the basis of appearance and functions that should be provided on all manual call points for use in fire detec
21、tion and fire alarm systems. The colours, dimensions, shapes and methods of operation are based on recognized operating principles that give confidence and recognition to the user when operating in genuine fire alarm situations. The purpose of a manual call point is to enable a person discovering a
22、fire to initiate the operation of a fire alarm system so that appropriate measures can be taken. It is important for manual call points to be recognizable and simple to use, without the requirement to read elaborate instructions so that anyone discovering a fire is able to use the manual call point
23、without previous familiarity with it. The intention of this part of ISO 7240 is to specify requirements for operation and reliability. The methods of operation of the manual call points covered are as follows: type A: direct operation (single action); type B: indirect operation (double action). Both
24、 types require the breaking or the visible displacement by change of the position of a frangible element forming part of the front face, which is considered as the most suitable method for general application and which acts as a deterrent to the misuse of the device. Importance has been placed on id
25、entifying the manual call point, the method by which it is activated and an indication to the user that the initiation of an alarm has been given. The resulting part of ISO 7340 takes into account national variances in custom and practice and language in bringing together common elements that contri
26、bute towards a standard device for use throughout the world. The performance of manual call points is assessed from results obtained in specific tests. This part of ISO 7240 is not intended to place any other restrictions on the design and construction of such manual call points. INTERNATIONAL STAND
27、ARD ISO 7240-11:2011(E) ISO 2011 All rights reserved 1Fire detection and alarm systems Part 11: Manual call points 1 Scope This part of ISO 7240 specifies the requirements, test methods and performance criteria for manual call points in fire detection and alarm systems in and around buildings (see I
28、SO 7240-1). It takes into account indoor and outdoor conditions, the appearance and operation of the manual call points for type A “direct operation” and type B “indirect operation”, and covers those which are simple mechanical switches, those which are fitted with simple electronic components (e.g.
29、 resistors, diodes) and those which contain active electronic components and which work with the control and indicating equipment for signalling and identifying, for example, an address or location. This part of ISO 7240 does not cover manual call points for special applications, for example manual
30、call points that are intrinsically safe or for use in hazardous conditions, if such applications require additional or other requirements or tests than those given in this part of ISO 7240. 2 Normative references The following referenced documents are indispensable for the application of this docume

38、lement component, composed of glass or having the appearance of glass and which after receiving a blow or pressure as instructed, is physically broken or is visibly displaced by change of position and remains in that condition until replaced or reset NOTE The frangible element is intended to give pr
39、otection against unintentional operation and to be a deterrent against misuse. The visible displacement of the frangible element is accepted as apparent breaking. 3.3 non-resettable frangible element frangible element that it is necessary to replace after the activation of the manual call point, in
40、order for the manual call point to be able to return to the normal condition 3.4 resettable frangible element frangible element that can be returned to its original position without replacement, in order for the manual call point to be able to return to the normal condition 3.5 front face area withi
