SMOKE DETECTORS:
The smoke detectors in your home are pre-wired, per electrical code requirements, into the mail electrical system if you have purchased a new home; the smoke detector is backed up with a 9-volt battery.
Homeowner’s Maintenance Guidelines;
Test the detectors and clean and vacuum the openings of the smoke detectors every six months. Visually inspect the clear button on the test switch to see that the indicator light is glowing. To test the alarm, press the test button for about ten seconds, or until the horn sounds lightly. Do not use an open flame to test the detector.
The unit will emit a low-frequency beeping noise if a malfunction or power failure occurs or if the battery is low. Change the 9 Volt battery every 6 months to ensure proper operation.
Thanks for your great information, the contents are quiet interesting. I will be waiting for your next post.
