The Chick-a-Dee ® smoke detector was specially developed for home interior, appealing to lovers of 'design' and families with children. The Chick-a-Dee ® smoke detector is equipped with a 1.5 year battery lifetime and a three-year warranty. The Chick-a-Dee ® takes its name and appearance from the American Black-capped Chickadee (Poecile atricapilla). This name is a tribute to its warning call, the phonetic Chickadee sound. At the smallest threat, the bird calls chick-a-dee-dee, and in more serious circumstances, the call becomes a loud dee-dee-dee sound. As soon as smoke is detected a 85 db alarm signal is activated. Under normal conditions, a control light flashes once a minute. The Chick-a-Dee can be tested by pressing the test button.
