标准摘要
[中文适用范围]： 本ISO 7240-20规定了用于建筑物内火灾探测和报警系统的吸气式烟雾探测器的要求、测试方法和性能标准。为保护特定风险而开发的吸气式烟雾探测器，如果其包含特殊特性（包括本ISO 7240-20未定义测试或评估方法的额外功能或增强功能），也属于本ISO 7240-20的覆盖范围。任何特殊特性的性能要求超出本ISO 7240-20的范围。 [外文原描述]： ISO 7240-20:2010 specifies the requirements, test methods and performance criteria for aspirating smoke detectors for use in fire detection and alarm systems installed in buildings. Aspirating smoke detectors developed for the protection of specific risks that incorporate special characteristics (including additional features or enhanced functionality for which ISO 7240-20:2010 does not define a test or assessment method) are also covered by ISO 7240-20:2010. The performance requirements for any special characteristics are beyond the scope of ISO 7240-20:2010.
