Fire detection and alarm systems, Part 15: Point type fire detectors using smoke and heat sensors (ISO 7240-15:2014, MOD)

The objective of this Standard is to specify requirements, test methods, and performance criteria for point-type fire detectors using smoke and heat sensors, incorporating in one mechanical enclosure at least one smoke sensor and at least one other sensor which responds to heat, and in which the signals of smoke sensors are combined with signals of the heat sensors.
