AS 7240.11-2008

Specifies requirements, test methods and performance criteria for line type smoke detectors utilizing the attenuation and/or changes in attenuation of an optical beam, for use in fire detection systems installed in buildings.

This part of ISO 7240 specifies the requirements, test methods and performance criteria for manualcall points in fire detection and alarm systems in and around buildings (see ISO 7240-1). It takes intoaccount 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 simplemechanical 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 andindicating 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 manualcall points that are intrinsically safe or for use in hazardous conditions, if such applications requireadditional or other requirements or tests than those given in this standard.
