After a smoke alarm from Kidde has been triggered, it is important to properly reset it to ensure that it functions correctly in the future. First, verify that the source of the alarm has been addressed, whether it was due to smoke or a false alarm caused by cooking or steam. To reset the alarm, locate the reset button on the smoke alarm unit, which is often found on the front or side of the device. Press and hold the reset button for approximately fifteen to twenty seconds. This action should silence the alarm and reset the unit for normal operation.
