The Kidde® i9010 is a 10 years, sealed battery, ionization, smoke alarm with alarm memory and Hush™ feature. The innovative design of this alarm automatic activation is unlike any other smoke alarm. The i9010 alarm will automatically activate when it is attached to the mounting bracket; there are no pull-tabs, no switches, everything is automatic. At the end of the alarm life, the unit will chirp, indicating the alarm is in need of replacement. The customer can use a simple tool such as a screwdriver to deactivate the unit, stopping the low battery chirp and making it safe for disposal. The sealed in board mounted battery will power the i9010 unit for its complete 10 years life. No replacement battery will ever be needed. The Kidde® i9010 sealed battery operated smoke alarm features a self-activation mechanism making installation simple and easy. It also features Hush™ feature allowing consumers to temporarily silence nuisance alarms and an end of life alert indicating it is time to replace the alarm. At the end of the alarm 10 years life, deactivation of the alarm is just as easy. Using a tool such as a small screwdriver, a deactivation switch removes power from the alarm and renders the battery safe for disposal. The alarm lockout feature mechanically prevents a deactivated unit from being mounted back on the mounting bracket. This alarm uses ionization sensing technology. Ionization sensing alarms may detect invisible fire particles (associated with flaming fires) sooner than photoelectric alarms. Photoelectric sensing alarms may detect visible particles (associated with smoldering fires) sooner than ionization 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.
