The Kidde 449 is a weatherproof surface mount back box built for outdoor fire alarm bell installations. Gray finish with an included gasket provides a sealed mount point for Kidde vibrating bells (models 439D through 445D) where indoor-rated boxes won't cut it.
Purpose-built for outdoor bell installs
When the job calls for a fire alarm bell on an exterior wall or in a weather-exposed location, standard back boxes invite moisture and corrosion. The 449 solves that with a gasketed weatherproof enclosure rated for surface mount applications. Pairs directly with Kidde's full line of 6", 8", and 10" vibrating fire alarm bells in both AC and DC configurations.

What bells does the Kidde 449 back box fit?
The 449 is compatible with the full Kidde vibrating fire alarm bell line: 6" models (439D, 439DF, 443D), 8" models (440D, 440DF, 444D), and 10" models (441D, 441DF, 445D).
Is the 449 rated for outdoor use?
Yes. The 449 is a weatherproof surface mount box that includes a gasket to seal against moisture in exterior or weather-exposed installations.
Can I use a standard indoor back box instead?
For exterior or exposed installations, no. Standard indoor boxes don't provide the weatherproof seal needed to protect bell wiring connections from moisture, corrosion, and environmental exposure. The 449 is purpose-built for that job.
Does the 449 come with mounting hardware?
The 449 includes the weatherproof back box and gasket. Refer to the spec sheet in the Documents tab for detailed installation and mounting requirements.
