Para aquellos que buscan un detector de humo económico, el primer paquete de 2 alertas SMI100 es una excelente opción a solo $ 29.99. Con una calificación de 4,5 estrellas de más de 22.500 reseñas, ofrece un rendimiento confiable y funciona con baterías para una fácil instalación.
Los detectores de humo que funcionan con batería, como el LSHOME 4 Pack, son más fáciles de instalar y perfectos para hogares sin cableado existente, con un precio de $41.99. Por el contrario, los modelos cableados como el First Alert BRK 9120B, con un precio de $97.19, proporcionan una fuente de alimentación continua y, a menudo, tienen funciones interconectadas para una mayor seguridad.
Busque detectores de humo con sensores fotoeléctricos, como la alarma de incendio de Rensecum, que son mejores para detectar incendios que humedecen. Además, considere modelos con botones de prueba para verificar fácilmente la funcionalidad, como el detector de batería de primera alerta a $16.99, que admite mantenimiento regular.
El mantenimiento regular es crucial para los detectores de humo; pruébalos mensualmente y reemplace las baterías al menos una vez al año. Polvorgue los detectores periódicamente para evitar falsas alarmas y sustituya los detectores de humo cada 10 años para asegurarse de que funcionen correctamente.
Marcas como First Alert y LShome son conocidas por su fiabilidad, y los detectores de humo de First Alert suelen recibir clasificaciones más altas para las opciones cableadas, como el BRK 9120B. LSHOME ofrece una solución más económica y económica con buenas críticas, lo que lo convierte en una opción sólida para las necesidades de batería.
Los detectores de humo suelen oscilar entre $12.99 y $111.99, dependiendo de las características y la marca. Para una configuración de seguridad integral, considere asignar alrededor de $ 30- $ 100 para una combinación de modelos con batería y cableados para garantizar la cobertura en toda su casa.
