My smoke alarm keeps chirping, even with a new battery. What is causing this?

There are a number of possible causes for your smoke alarm to keep chirping even with a new battery.
• It is possible that your smoke detector "silence" button was pushed by mistake. The alarm will now "chirp" once a minute for up to 15 minutes before resetting.
• Are you sure it's the smoke alarm? funny to ask, but other devices have similar low battery chirps or warning tones.
• Even "new" batteries may not be fresh. If batteries are stored, especially in cold areas like refrigerators, they lose their charge more quickly. Always check the freshness date on the package when buying new batteries. Keep plenty of replacement batteries on hand so that you are sure to always be protected by your smoke alarms.
