Annotation of standard text ČSN EN 54-22+A1 (342710):

Tato evropská norma platí pro nulovatelné lineární hlásiče teplot, které se skládají ze snímacího prvku využívajícího optické vlákno, pneumatickou trubičku nebo elektrický senzorový kabel připojený k řídicí jednotce senzoru buď přímo, nebo pomocí modulu rozhraní, který je určen pro použití v elektrické požární signalizaci instalované uvnitř a v okolí budov a jiných inženýrských objektů (viz EN 54-1:2011). Tato evropská norma specifikuje požadavky a kritéria provedení, příslušné zkušební metody a upravuje posuzování a ověření stálosti vlastností (AVCP) nulovatelných lineárních hlásičů teplot podle této EN. Tato evropská norma rovněž zahrnuje nulovatelné lineární hlásiče teplot určené pro použití v rámci lokální ochrany technologického celku a zařízení. Tato evropská norma nezahrnuje nulovatelné lineární hlásiče teplot se speciálními charakteristikami a vyvinuté pro speciální rizika. Tato evropská norma nezahrnuje lineární hlásiče teplot, jejichž základem jsou nenulovatelné elektrické kabely s pevně danou teplotou (tzv. "digitální" systémy)
