JCFD encourages you to change Smoke Alarm batteries at least once each year. An easy way to remember is to change these batteries when you change your clock. Replace old batteries with fresh, high quality batteries to keep your Smoke Alarms ready to protect you all year-long

Check Your Smoke Alarms

After inserting fresh batteries in your Smoke Alarm, make sure the Alarm is working by activating the safety test button. JCFD recommends that you test all of your Smoke Alarms at least once each month. If you have any doubt regarding the working condition of a Smoke Alarm, we recommend you replace it.

Count Your Smoke Alarms

JCFD highly recommends that you have a properly functioning Smoke Alarm in every sleeping room -and- in the hallway directly adjacent to those rooms. If sleeping rooms are on an upper level, a Smoke Alarm should also be installed in the center of the ceiling directly above the interior stairway.

It's best to have at least one working Smoke Alarm on every level of your home, including the basement and family room. To assure optimal protection and avoid false alarms, your Smoke Alarm must be mounted properly. You'll find simple instructions included with every Smoke Alarm you purchase. Should questions remain, we encourage you to visit or contact us for help.

Clean Your Smoke Alarms

Help your Smoke Alarm remain sensitive and ready to protect you by gently using a vacuum cleaner once a month to remove dust and cobwebs. If your Smoke Alarms have been accidently painted or contaminated, replacement may be necessary.

Retire your old Smoke Alarms!

Lastly, if your smoke detectors are more than 10 years old ... replace them. When you go to sleep at night, your sense of smell is one of the first senses to "go to sleep". A working smoke detector(s) can be thought of as your "nose" while you sleep.
