The Kidde P4010ACLEDSCA is an integrated 120V AC hardwire smoke alarm with 10-year sealed battery backup and LED strobe light that provides temporal patterns, visual and voice warnings. The model P4010ACLEDSCA is equipped with a 177 candela strobe light (powered by Cree® LEDs), designed to notify the deaf and hard of hearing. The unique design measures only 5.8 cm (2.3”) in height, when mounted.
This alarm uses photoelectric sensing technology. Photoelectric sensing alarms may detect visible particles (associated with smoldering fires) sooner than ionization alarms. Ionization sensing alarms may detect invisible fire particles (associated with flaming fires) sooner that photoelectric alarms. Kidde strongly recommends that both ionization and photoelectric smoke alarms be installed to help insure maximum detection of the various types of fire that can occur within the home.
