What to do if my Ei Electronics Smoke Alarm doesn't sound when I press the test button?

If your Ei Electronics Smoke Alarm fails to sound when you press the Test button, consider the age of the unit by checking the replace-by label on the side. For 9V Replaceable Battery models, ensure the battery snaps are firmly connected. If you have a 10 Year Lithium Battery model, make sure the unit is twisted fully home on the mounting plate to connect the battery.
