ISO 7240 pdf download Fire 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 ISO 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. 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 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.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 7240-1 and the following apply.
3.1
alarm condition
condition of the manual call point after the operating element has been activated
3.2
frangible element
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
3.3
non-resettable frangible element
frangible element that it is necessary to replace after the activation of the manual call point, in order for the manual call point to be able to return to the normal condition
