The P4010ACLEDSCA model from Kidde is a smoke alarm that can be integrated with a 120 V AC wire-in system. It comes with a sealed battery backup that lasts for 10 years and has a LED strobe light feature that provides visual and voice warnings with temporal patterns. The alarm has been designed to be especially useful for those who are hard of hearing or deaf, as it includes a 177 candela strobe light that is powered by Cree® LEDs. Despite its advanced features, the smoke alarm has a compact design and measures only 5.8 cm (2.3 inches) in height when mounted.
