Fire Protection

This document specifies requirements, test methods, performance criteria, and manufacturer's instructions for smoke alarms that operate using scattered light or transmitted light (Type A- optical) or ionisation (Type B-ionisation), intended for household or similar residential applications.

This document includes additional requirements for smoke alarms which are also suitable for use in leisure accommodation vehicles.

For the testing of other types of smoke alarms, or smoke alarms working on different principles, this document should only be used for guidance. Special features of smoke alarms or special characteristics and developed for specific risks, are not covered by this document.

This document allows, although it does not require, the inclusion within the smoke alarm of facilities for interconnection with other similar smoke alarms and/or accessories, and for alarm silencing. Where such facilities are included, this document specifies applicable requirements.

This document does not cover the requirements for devices intended for incorporation in systems using separate control and indicating equipment.

NOTE          Certain types of smoke alarms contain radioactive materials. The national requirements for radiation protection differ from country to country and they are not specified in this document. Such smoke alarms should, however, comply with the applicable national requirements.

This part of ISO 7240 specifies the design, installation, commissioning and service requirements for a fire detection and alarm system (f.d.a.s.) (see ISO 7240‑1:2005, Figure 1), which is primarily intended to provide early detection of fire and notification within one or more specified indoor or outdoor areas for the protection of lives. The f.d.a.s. includes automatic detection and manual initiation of a fire, and audible and visual warning to people within the detection area.

This part of ISO 7240 also specifies requirements for f.d.a.s. capable of providing signals to audible warning systems in accordance with ISO 7240-19, to initiate the operation of ancillary technical services, such as fixed fire extinguishing systems, and to other precautions and actions.

The protection of property is outside the scope of this part of ISO 7240. However the requirements specified herein may be used for property protection.

This European Standard specifies requirements, test methods and performance criteria for point-type multi-sensor fire detectors for use in fire detection systems installed in buildings (see EN 54-1:1996), incorporating in one mechanical enclosure at least one optical or ionization smoke sensor and at least one carbon monoxide (CO) sensor and optionally one or more heat sensors. The overall fire detection performance is determined utilizing the combination of the detected phenomena.

This European standard specifies the evaluation of conformity (EoC) and the marking of the products concerned (i.e. multi-sensor fire detectors).

Multi-sensor fire detectors having special characteristics suitable for the detection of specific fire risks are not covered by this standard. The performance requirements for any additional functions are beyond the scope of this standard (e.g. additional features or enhanced functionality for which this standard does not define a test or assessment method).

NOTE          Certain types of detector contain radioactive materials. The national requirements for radiation protection differ from country to country and they are not specified in this standard.
