## Description

The Kidde i1040 is a 10-year, sealed battery, ionization, smoke alarm with Alarm Memory and Hush® feature. The i1040 alarm will automatically activate when it is attached to the mounting bracket; there are no pull-tabs, no switches, everything is automatic. When the unit reaches low battery condition (approx 10 years after power up), it 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 i1040 unit for its complete 10-year life. No replacement battery will ever be needed. 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.    Sealed-In Lithium Battery – Sealed-in lithium power supply; no battery replacement required over the 10 year life of the alarm. Eliminates worry about battery removal or unauthorized deactivation of alarm.   Self Activation – Alarm automatically activates when attached to the mounting bracket.   Alarm Memory – Rapidly flashing LED alerts user if the alarm has sounded since the last time the test/reset button was used.   Will temporarily silence nuisance alarms and will not allow Hush® mode to be activated unless the unit is in alarm mode.   Test/Hush® Button – Tests unit’s circuit operation and resets memory after an alarm condition occurs.   LED – A flashing red indicator light with four modes of operation: standby, alarm mode, Hush® mode, and memory set.
