10. Kidde 900-0136-003 Nighthawk Smoke Alarm

The Kidde i9010 is a 10-year, sealed battery operated smoke alarm featuring Hush, Alarm Memory, and a self-activation mechanism that makes installation simple and easy. The alarm will automatically activate when it is attached to the mounting bracket; there are no pull-tabs, no switches--everything is automatic. The sealed-in board-mounted battery will power the i9010 unit for its complete 10-year life. No replacement battery will ever be needed, and an End of Life alert indicates when it is time to replace the alarm. At the end of the alarm’s 10-year 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. As an added safety mechanism, the alarm lockout feature prevents a deactivated unit from being mounted back on the mounting bracket. The i9010 also features Hush™ technology, allowing consumers to temporarily silence nuisance alarms, and an Alarm Memory feature that alerts the user via rapidly flashing LED lights if the alarm has sounded since the last time the test/reset button was used. 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.
