How long will a smoke detector chirping after changing battery is a good question for someone who have been disturbed by chirping detector with full power. Today we are going to dive into it and offers some helpful solution.
Why Is My Smoke Detector Still Beeping After Changing the Battery?
Poor Battery Contact
Battery polarity may be incorrectly installed. Alternatively, there may be dirt or oxide in the battery contacts, resulting in poor contact.
Residual Power
Even if the battery has been removed, the circuit inside the smoke sensor may still retain some power. That power might be enough to trigger a beep.
High Air Humidity
In environments with high humidity, the smoke sensor’s sensor may be disturbed to trigger an alarm. In addition, moisture condensation inside the smoke sensor may also lead to a short circuit or sensor failure.
High Temperature
In high-temperature environments, the electronic components inside the smoke sensor may be subjected to thermal stress, so its performance is unstable or faulty.
High temperatures can also affect the sensitivity of smoke sensors and trigger false alarm. Especially in the hot summer, if the indoor temperature is too high, the smoke sensor may alert due to the influence of the heat wave.
Too Much Sensibility
In some circumstances, the smoke sensor may be too sensitive. For example, steam produced during normal cooking may trigger high- sensitive smoke sensors.
Fault
The circuit inside the smoke sensor may fail, causing alerts continuously.
End of Lifespan
As an electronic device, its internal components will naturally age over time. Aging may cause performance degradation or failure.
Smoke Detected
If the smoke sensor detects smoke, it may continue to sound an alarm.
How Long Will A Smoke Detector Chirping After Changing Battery?
When the battery is replaced, the beep emitted by the smoke sensor usually lasts from a few seconds to a few minutes, depending on the model and brand of the smoke sensor. We found several mainstream smoke detector on the market and investigated its Chirping time after power change.
Brand: First Alerts
Product Code:1039807
Chirping Period After Changing Battery: 60s
Brand: KIDDE
Product Code: PI9010
Chirping Period After Changing Battery: a few seconds
Brand: GST
Product Code: JTY-GF-GSTN701B
Chirping Period After Changing Battery: Short for a few seconds
Do You Have to Reset Smoke Detector After Changing Battery
It must, or it may continue Chirping because of residual electricity. The circuit design of the smoke detector may include capacitors, which are used to store electrical energy. When the device is powered off or turned off, some electrical energy may remain in these capacitors. We can press the reset button on the detector to achieve the reset operation. This button will connect or disconnect parts of the circuit, so that the capacitor in the circuit may be discharged.
What to Do When Smoke Alarm Keeps Beeping
Reset the Device to Drain Residual Electricity
After finding the reset button, we press and hold it until the detector gives a confirmation sound, which indicates that the reset has been successful. After the reset, we observe the smoke detector indicator light to determine whether it is normal.
If replacing the battery and resetting does not solve the problem, we can try disconnecting the power to the smoke detector. Then, we wait for a period of time (minutes to hours) for the capacitors inside the detector to discharge.
Finish the Battery
When the smoke detector battery is in poor contact, we first disconnect the power supply to ensure safety. Next, we check the positive and negative contact points of the battery and see if there is oxide or dirt. If there is, we clean it up with a dry cloth. At the same time, don’t forget to check for loose or deformed connectors.
When reinstalling the battery, we should ensure that the positive and negative electrodes are oriented correctly. If the smoke detector is powered by a power cord, we can check that the metal pin at the power cord connector is intact. After completing these steps, we should switch the power back on and test the operation of the smoke detector.
Reinstall Device in A Proper Place
The detector should be installed in a well-ventilated location, such as corridors, stairwells, halls, bedrooms, and living rooms.
Because the kitchen usually produces oil smoke, the detector should be installed far away from the cooking utensils. The recommended distance is at least three meters. Besides, please avoid installing the detector directly under the range hood or near the cooking area. Also, smoke detectors should be kept away from fire, heat, power and other sources of interference. This prevents false alarms or affects its sensitivity.
The machine should stay away from direct sunlight to avoid damage to the detector surface due to high temperature.
Sensitivity Adjustment
For smoke detectors with adjustable sensitivity, we usually have to open the case of the device or access its settings screen in the app. This may require specific tools and following the steps in the manual.
Then, in the settings screen of the device, we find the options related to sensitivity. It is usually “Sensitivity”, or “Sensitivity Level”. Depending on the actual needs, we adjust the sensitivity in the interface or with tools. Generally speaking, some devices may allow you to choose a preset sensitivity level, while others may allow you to make finer adjustments. Anyway, after adjusting the sensitivity, we should make sure to save the settings before exiting the settings page.
Replace aging device
Pay attention to the lifespan of the smoke detector. If it exceeds the estimated service life on the manual, please replace the device with a new one. This is not only a solution to its continuous chirping, but also a measure to ensure home safety.
FAQ Related to How Long Will A Smoke Detector Chirping After Changing Battery
How to Change Batteries in Smoke Detectors?
First, we open the battery compartment cover according to the smoke detector model and design. Then, we remove the old battery in order to properly install the new battery. What should not ignored is that the positive and negative electrodes of the battery are supposed to match the markings inside the detector. Finally, we re-close the battery compartment cover and secure other parts of the detector. If the detector comes with a test button, please press it to check proper operation.
Fire Alarm Beeping Every 30 Seconds
If the fire alarm is powered by battery, going off every 30 seconds may be a warning of low battery power. If the alarm has been in use for a long time, it may be due to the accumulation of dust inside the alarm. In this case, we can use a vacuum cleaner or a soft brush to clean the alarm. If the alarm still rings every 30 seconds after replacing and cleaning the battery, there may be a fault in the device itself. In this case, we recommend contacting a professional repairman or manufacturer for an overhaul or replacement.
Fire Alarm Beeping Every Minute
If the smoke detector goes off every minute, it may be due to extremely low battery power, internal dust accumulation, failure, and the environment.
