The document specifies the requirements and methods of test for manual call points in fire detection and fire alarm systems in and around buildings. 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 panels for signalling and identifying, for example, an address or location. It does not cover manual call points for special applications, for example manual call points that are intrinsically safe or for use in hazardous conditions.
