The objective of this Standard is to specify requirements, test methods, and performance criteria for point-type multi-sensor fire detectors that incorporate at least one carbon monoxide (CO) sensor in combination with one or more heat sensors, for use in fire detection and alarm systems installed in buildings (refer to AS ISO 7240.1).

This part of ISO 7240 has been prepared by the Subcommittee ISO/TC 21/SC 3 and is based on ISO 7240-8:2007.

A fire detection and fire alarm system is required to function satisfactorily not only in the event of a fire, but also during and after exposure to conditions likely to be met in practice such as corrosion, vibration, direct impact, indirect shock, and electromagnetic interference. Some tests specified are intended to assess the performance of the fire detectors under such conditions.

Test Fires TF2, TF3, TF4, and TF5 from ISO/TS 7240-9 have been included to verify the detection performance of point fire detectors using a combination of carbon monoxide and heat sensors (CO) sensors. TF4 and TF5 specifically demonstrate the influence of the heat sensor(s). For these Test Fires, the CO level and, where applicable, the temperature is used as test validity criteria. This part of ISO 7240 is not intended to place any other restrictions on the design and construction of such detectors.
