ISO 7240-11:2011规定了建筑物内及周围火灾探测和报警系统中手动呼叫点的要求、试验方法和性能标准（见ISO 7240-1）。它考虑了室内和室外条件，A型“直接操作”和B型“间接操作”手动呼叫点的外观和操作，并涵盖了简单机械开关，装有简单电子元件（如电阻器、二极管）和含有有源电子元件，并与控制和指示设备一起工作以发送信号和识别地址或位置的设备。 ISO 7240-11:2011不包括特殊应用的手动呼叫点，例如本质安全的手动呼叫点或用于危险条件的手动呼叫点，前提是此类应用需要ISO 7240-11:2011规定以外的其他要求或测试。

ISO 7240-11:2011 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. ISO 7240-11:2011 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 ISO 7240-11:2011.
