Smoke Detector Maintenance
It is extremely important to regularly test and clean all detectors.
Replace the batteries in battery-operated units once a year or in accordance with the manufacturer's recommendations.
Teach everyone in your house to leave working batteries in smoke detectors and not to use them elsewhere.
They should not be painted.
To test and clean a detector, follow the manufacturer's instructions.
Cobwebs and dust can impair a detector's sensitivity; most units should be vacuumed at least once a year.
