Replace 3 smoke detectors 1 unit on each of the 3 floors. The reason for today’s visit was to check the smoke detectors that were randomly going off in the home. After closer inspection, we found that the smoke tactor‘s were roughly 11 years old and due for replacement. We went ahead and replaced all three smoke detectors at the Home with new standards of detectors as there is no gas, burning appliances, or attached garage.
