1. It is indisputable that smoke alarms save lives. Smoke alarms are the best and least expensive way to provide an early warning system to alert you and your family to a potential fire emergency. Smoke alarms are designed to detect a fire in its early stages and alert people so they have time to safely escape.
2. Smoke alarms should be installed in every bedroom, outside each sleeping area and on every level of the home.
3. For the best protection, smoke alarms should be interconnected. What does that mean? When one sounds they all sound alerting you to an emergency early on and giving you critical time to escape. New construction requirements have included hard- wired smoke alarms with battery back-ups since the 1980's.
Always read the manufacturer’s recommendations as some models recommend replacement every 5-7 years.
5. Never (ever) paint over a smoke alarm. It will affect the operation of the smoke alarm, potentially disabling it.
6. Test your alarms once a month by pressing the test button.
7. Clean your smoke alarm once a month when you test it. Smoke alarms get clogged with dust build-up which may affect performance.
8. If your detector “chirps” it may be time to change the back-up battery in your hard-wired alarm. Since 2018, Maryland law has required all battery-only smoke alarms (permitted in homes built b/f 1975) to have a sealed,10-year long-life battery in the unit so any "chirping" in these units is likely signaling that you need to replace the smoke alarm with a new one.
