Battery-Operated Is Not Always Enough
Standalone battery-operated detectors are better than nothing, but they have real limitations. Batteries die, often without a functioning low-battery warning, and detectors that are not interconnected mean an alarm in one part of the house may not be heard in another. Hardwired smoke and carbon monoxide detectors solve both of these problems. Connected directly to your home’s electrical system with a battery backup, they do not depend on a battery that was last changed sometime before you can remember. Interconnected hardwired detectors communicate with each other, so when one triggers, every alarm in the home sounds simultaneously. In a fire or CO event where seconds matter, that distinction is not a minor one.
Proper Placement Is as Important as the Detectors Themselves
A detector installed in the wrong location provides far less protection than one placed correctly. Smoke detectors should be installed on every level of the home, inside each bedroom, and outside sleeping areas. Carbon monoxide detectors belong on every level and near sleeping areas, since CO poisoning is most dangerous when people are asleep and unable to notice symptoms. Detectors placed too close to kitchens or bathrooms can generate nuisance alarms from cooking steam or shower humidity, which leads homeowners to disable them. Our licensed electricians follow current placement guidelines and apply practical judgment to ensure your detectors are positioned for reliable protection without unnecessary false alarms.
Hardwired Installation and Interconnection
Installing hardwired detectors involves running low-voltage wiring that connects each unit to the others in a network, so all devices communicate when any one of them is triggered. In new construction this wiring is built in from the start. In existing homes it requires routing wire through walls and ceilings to link each detector location. A.W.E. handles the full installation, from running the interconnect wiring to connecting the devices and testing the entire system before we leave. If your home already has hardwired detectors that are aging or no longer communicating correctly, we can assess the existing wiring and replace the devices without disturbing what is already in the walls.
When to Replace Your Existing Detectors
Smoke detectors have a recommended replacement interval of ten years from the date of manufacture, and carbon monoxide detectors should be replaced every five to seven years. Many homeowners are surprised to find that the detectors in their home are well past these intervals. An aging detector may still sound when tested with the test button, but that test only confirms the alarm circuit works. It does not confirm that the sensing element is still capable of detecting smoke or CO at the concentrations that matter. If you do not know when your detectors were manufactured, checking the date stamp on the back of each unit is worth the few minutes it takes.
