Dispositif d'alarme de fumée

La présente Norme européenne spécifie les exigences, les méthodes d’essai, les critères de performance et
les instructions du fabricant pour les dispositifs d’alarme de fumée qui utilisent le principe de diffusion ou de
transmission de la lumière (optique de type A), ou de l’ionisation (ionisation de type B), pour des applications
domestiques ou similaires.
La présente norme inclut des exigences supplémentaires concernant les dispositifs d’alarme de fumée qui
conviennent également à une utilisation dans des camping-cars.
Pour les essais relatifs à d’autres types de dispositifs d’alarme de fumée ou à des dispositifs d’alarme de
fumée fonctionnant selon différents principes, il convient que la présente norme soit utilisée à titre de guide
uniquement. Des particularités spéciales pour dispositifs d’alarme de fumées ou des caractéristiques
spéciales et conçues pour des risques spécifiques, ne sont pas couvertes par la présente norme.
Cette norme permet, le cas échéant, d’inclure dans le dispositif d’alarme de fumée des dispositifs
d’interconnexion avec d’autres dispositifs d’alarme de fumée similaires et/ou accessoires, et de neutralisation
de l’alarme. Lorsque des dispositifs de cette nature sont inclus, cette norme spécifie les exigences
applicables.
Cette norme ne couvre pas les exigences relatives aux dispositifs destinés à être incorporés dans des
systèmes qui utilisent des équipements de commande et d’indication séparés.
NOTE Certains types de dispositifs d’alarme de fumée contiennent des substances radioactives. Les exigences
nationales en matière de protection contre les radiations varient d’un pays à l’autre et ne sont donc pas spécifiées dans la
présente norme. Il convient toutefois que des dispositifs d’alarme de fumée de ce type soient conformes à la
réglementation nationale applicable.

— the quiescent load of the smoke alarm;
— the additional load resulting from a monthly test in accordance to the manufacturers
specification;
— loads due to the radio circuitry and radio frequency messages (if applicable);
— the additional load of the interconnection-test at least every 6 months or more often, if
specified by the manufacturer (if applicable).
If a separate battery is used for the radio frequency link, the tests and calculations shall be repeated for
each battery. In this case the maximum battery service life shall be based on the results on that battery
which give the shortest calculated duration.
c) For smoke alarms with additional features not described in this standard using battery power
during mains failure, the above requirements shall also be met.
The manufacturer shall document in the user manual its underlying assumptions about the average
frequency of usage of these functions and proof by calculation that battery service life of 1 year or
longer can be achieved.
If it cannot be proven that the 1 year battery service life can be achieved, a separate power supply shall
be used for additional features and the calculation shall be done for the battery dedicated to smoke
alarm function.
If the power for the additional features is provided by a separate battery, then there shall be no audible
indication of low battery warning for this battery on the smoke alarm.
d) At the point when the battery fault warning commences, the batteries shall have sufficient capacity
to give an alarm signal as specified in 4.2.1 and 4.2.6 for at least 4 min in the event of fire, and in the
absence of fire, a battery fault warning for at least 30 days, and for smoke alarms with radio
frequency interlink, one radio frequency alarm signal in the event of fire.
e) To verify battery service life, data concerning the smoke alarm loads and the battery characteristics
shall be provided to indicate that the above requirements can be met at normal ambient conditions.
To confirm this, the smoke alarm shall be tested in accordance with 5.2.2.2.2.
4.2.2.2.3 Rechargeable back-up power source
The rechargeable back-up power source shall be capable of supplying the smoke alarm with a quiescent
load for a minimum period of 72 h followed by an alarm signal as specified in 4.2.1 or at least 4 min and
a fault warning for at least 24 h.
To confirm this, the smoke alarm shall be tested in accordance with 5.2.2.2.3.
4.2.2.2.4 Monitoring of back-up power source
Each back-up power source shall be monitored by the smoke alarm for low back-up faults. Replaceable
back-up power sources shall be monitored by the smoke alarm for open circuit and short circuit failure
of the back-up.
In each case the audible low battery warning signal shall be given at least once every minute.
To confirm this, the smoke alarm shall be tested in accordance with 5.2.2.2.4.
4.2.2.3 Battery powered smoke alarm devices
For battery powered smoke alarm devices the following shall apply:
a) The battery power supply shall be replaceable by the user unless the battery service life is 10 years
or greater.
b) The primary battery/batteries supplied with or specified for us
