No matter for eliminating noise or operation recovery, resetting the smoke alarm is a necessary operation after its alerts. This blog will introduce the function, work principle, location of the reset button and tell how to reset smoke alarm. Let’s dive into it.
Functions of Smoke Reset Button
Mute Noise
When the smoke alarm sounds due to the detection of smoke, we can press the reset button to mute the alarm.
Reset
The reset button also restores the smoke alarm to its initial state. After confirming that smoke or other potential hazards have been eliminated, we can press this button to set it back to normal working condition. This makes it possible to accurately alert when it detects smoke again next time.
Cancel Alerts
If the smoke alarm goes off due to a false alarm, please press the reset button to cancel the alarm status.
Equipment Maintenance
Regular equipment maintenance is the key to ensure that the smoke alarm works properly. During maintenance, it may be necessary to press the reset button to test the operating status of the equipment. Or, we have to restore the equipment to factory settings for further inspection and adjustment by the resetting button.
Clear Residual Power
After the reset button is pressed, a reset process may be performed inside the alarm. This can clear the current alarm status, reset the timer, and re-initialize the internal circuit. So some energy storage components (such as capacitors) will discharge the residual electricity.
How Does Smoke Reset Button Work?
Smoke alarms comes with a complex electrical system where the reset button connects. These circuits remain energized during normal operation, while the pressing of the reset button may trigger an internal circuit that causes reset or temporary power lost .
When Do Smoke Detector Need to Be Reset?
Cancellation After False Alarm
When the smoke alarm mistakenly alarms because of smoke, dust, insects, we can press the reset button to cancel the current alarm state.
Reset After Going off
After confirming that smoke or other potential hazards have been eliminated, pressing the reset button can restore the smoke alarm to its initial state. So it can accurately sound the alarm if smoke is detected again in the future.
Equipment Testing and Maintenance
Regular equipment testing is the key to ensuring that smoke alarms work properly. During the test, it may be necessary to press the reset button to check whether the device’s response speed and alarm function are normal.
When performing equipment maintenance, such as replacing batteries or cleaning sensors, it may also be necessary to press the reset button to reinitialize the device.
Activation After Power Replacement
If replacing with a new battery, it is usually necessary to press the reset button to activate the alarm. This allows it to function normally.
Troubleshooting and Repair
If the smoke alarm is malfunctioning or not working properly, pressing the reset button may be an attempt to fix the problem. However, if the problem persists, we recommend contacting a professional for an overhaul.
Where is Smoke Alarm Reset Button?
The reset button of the battery smoke alarm is usually located on the front or side of the device. It could be a button labeled “RESET” or something similar.
How to Reset Smoke Detector
Electric Smoke Detectors with Battery Backup
We can gently press the reset button for a few seconds. This usually causes the smoke alarm to emit a brief beep or flashing indicator, which indicates that a reset operation is in progress. After releasing the reset button, we wait a few seconds for the smoke alarm to complete the reset process. At this point, the flashing light and the beep may stop blinking.
Battery-Powered Smoke Detectors
For some hard-wired smoke alarms, you may need to turn off the main switch of the home circuit before you can reset it. And, the following step is similar to that of the battery type.
FAQ
Why Is My Smoke Alarm Beeping If There’s No Fire?
- A low battery charge can cause the alarm to sound jerky or in a low voice.
- Clogged or dusty sensors can cause false positives.
- Too much humidity or too low temperature in the room can also result in false positives.
- Installed in a dark and humid place will affect its normal operation.
How Do I Stop a Smoke Alarm from Beeping in the Middle of the Night?
1. First, try replacing the battery. Because low electricity is a common cause of alarm buzzes.
2. Check and eliminate smoke, dust or steam factors.
3. If the problem cannot be solved immediately, we can check whether the alarm comes with a mute button. Alternatively, we can disconnect the power supply to temporarily stop the buzz. But do not forget to address the underlying problem as soon as possible.
4 If the the above operations do not work, it is necessary to contact a professional.
How Do I Know If an Electrical Problem Is Affecting My Smoke Detector?
We can observe the indicator of the smoke detector to determine whether the circuit is working properly.
