To ensure complete protection, it is recommended to place one alarm on each level of the home and in each bedroom. The features are similar to those of the SA340CN and SA340B models, but the First Alert tamper-resistant, lithium battery-powered smoke alarm adds the Sealed Battery Technology.

First Alert has been the most trusted brand in home safety since launching the first residential smoke alarm in 1958, according to a First Alert Brand Trust Survey conducted in February 2018.
