Almost all types of smoke alarms will beep to let you know when it’s time to change the battery. Inevitably, this first beep is heard around 3 am, when you sleep deeply (according to Murphy’s law, of course).
If you prefer not to risk being awakened by the beep, you can anticipate it by proactively replacing the battery according to a regular schedule. Most detectors work for about 6 months with a battery, so the common advice is to replace the batteries twice a year . A good time to replace all the batteries in your smoke alarms, because it serves as a biannual reminder, is the weekend when we set our clocks for daylight saving time and return to normal time.
Smoke detectors can be battery powered or plugged directly into the home’s electrical system. But almost all smoke detectors, including those that operate at home, contain a battery. The detectors that are hardwired to the house’s electrical system use this battery to provide backup power in case a fire destroys the house’s power supply.
Battery operated smoke detectors and home smoke detectors will beep or beep the low battery alarm. This alarm is different from the deafening fire alarm that occurs during a fire: It is a tweet or a sporadic beep, not a constant breath.
Sometimes it can be difficult to determine which smoke detector in your home is beeping. As a general rule, the lower the battery, the more the detector beeps. So, once he begins to chirp, you must either park yourself (and possibly other family members) near each detector and wait for the next chirp, or let the battery become weaker. tweets sound frequently. Obviously, the second alternative is far from ideal because you risk the possibility that the detector stops working. That is why it is wise to change all batteries twice a year at a convenient time.
Step by step instructions
If you hear the beep or chirp of the low battery alarm, do not ignore it and never remove the battery without replacing it with a new one. Smoke detectors with fully functioning batteries are essential to the safety of your family and your home. Unfortunately, reports of tragic fires often indicate that the house is equipped with smoke detectors, but these detectors have been disabled.
Note : New lithium battery smoke detectors last up to 10 years. With these, the entire device is disposable. If your home has this type of detector, you will need to replace the entire unit.
Most conventional smoke detectors have a friction cover that folds down or lifts. In some cases, the whole body of the smoke detector attaches to a base attached to the ceiling or wall. To remove them, you usually give the body a twist in the opposite direction of clockwise.
Step by step, here’s how to change the battery of a smoke detector :
- Remove the lid or body. Gently open the cover or detach the detector body from its base with a slight twisting motion. Inside, you’ll find three main parts: the sensing chamber, a horn and a battery (and in some cases, a voltage source of the house).
- Replace the battery. Detach the old battery from its holder. Most detectors use a 9-volt battery – use a new 9-volt lithium battery instead. Make sure that the male and female terminals are correctly oriented and that they connect well with the base.
- Close the lid or replace the body. Close the lid or lock the body of the smoke detector in its base.
- Test the detector. Press the test button on the detector surface to make sure the battery is working. When you press the button, the detector should beep or chirp.
