How Often Should Hard-Wired Smoke Detectors Be Replaced? As mentioned before, smoke detectors should be replaced every 10 years. After about a decade, your sensors will become weak and less efficient, which makes it less likely for them to perform their most basic function: detecting smoke in your home.
In this way, can you replace a hard-wired smoke detector with a battery one?
Replacing a hard-wired smoke detector is almost as easy as replacing a battery-powered version. … You’ll also need a non-contact voltage detector (Photo 1) and a wire stripper. Turn off the power at the main electrical panel and disconnect the old alarm (Photo 1).
Replace your smoke alarm. Some models last as little as 5 years. This includes battery operated and hard-wired alarms. All smoke alarms have an expiration date.
Moreover, do hardwired smoke detectors need replacing?

Do wired in smoke detectors go bad?
Smoke detectors are never “off” — they are monitoring the air for smoke around the clock, year in, year out. They have a shelf life and should generally be replaced every 8 to 10 years.

If smoke enters the chamber where those plates are located, it disrupts the flow of ions and triggers the alarm. That radioactive material is only effective for about 10 years.
Why did my smoke alarm go off in the middle of the night for no reason?
The most likely reason smoke detectors go off unexpectedly is that people aren’t changing the batteries in them often enough. In most sensors you might think of, the strength of the signal goes up when they detect what they’re supposed to.
