ISO 7240-27:2025 Scope

This document specifies requirements, test methods and performance criteria for multi-sensor point fire detectors that incorporate a smoke sensor, a carbon monoxide (CO) sensor and, optionally, one or more heat sensors, for use in fire detection and alarm systems installed in buildings (see ISO 7240-1).

This document is not applicable to fire detectors using smoke, CO and, optionally heat sensors, which have special characteristics, and which have been developed for specific risks. For the testing of other types of fire detectors using smoke, CO and, optionally, heat sensors working on different principles, this document can therefore be used only for guidance.
