How To Turn Off First Alert Smoke Alarm?
To turn off your first smoke alarm, just take out the battery. But if you wish to remove or disconnect it, you need to do more than that.
First, rotate your first alert smoke alarm counterclockwise. Then take it out of the mounting bracket. You’ve to twist it a little to disengage the lock pin from the mounting bracket.
If it is a hardwired first-alert smoke alarm then just turn off the power from the circuit breaker. Then just like the nonhardware option take off the mounting bracket and twist out to disengage the lock pin.
Why the Unexpected Alarm?
An unexpected alarm can happen for a lot of reasons from a power outage issue to the device getting expired. Make sure to troubleshoot the smoke alarm properly before getting to a solution.
Let’s go through each of the reasons in detail.
Review 1: System Expiration Check
Check the expiration date of the smoke alarm. If it has been more than 10 years of use then it is time to change the detector. These alarms can last without any problem for about 7 to 10 years.
If it is way past the expiration date then chances are the blinks and beep are because of surpassing its expiry date.
Review 2: Clogged Fire Alarm
If the sensor of the smoke detector gets clogged by dirt, debris, or bugs then it will not work properly. The result will be an unwanted beep.
It’s possible that an alarm can be triggered by the debris or the spiderweb. It’s one of the common causes of false fire alarms. To prevent it, the alarm unit’s chamber should be cleaned from time to time.
Since you’re dealing with the sensor, cleaning smoke detectors should be done with utmost care. Uninstall the alarm first and then clean it with a soft brush.

It can also be cleaned with compressed air. Reinstall the alarm after cleaning it.
Review 3: Location of The Alarm
If the smoke detector is placed near moving air or any source of stream then it can trigger a beep. Besides, don’t place it in the bathroom as well since the steam can trigger the alarm.
In addition, the alarm must not be placed under direct sunlight, fluorescent lighting, or any HVAC vents. Placing in one of these places increases the chance of receiving false alarms.
Furthermore, too much light creates heat which may give a wrong signal to the sensor.
Review 4: Power Outage Problem
A loose hot wire connection can cause an AC or DC fire alarm to lose power. It has the same effect as power failures. When the power is restored, the system may buzz for a while.
It is a systematic malfunction that can be solved by a technician. Also, make sure to check the fire suppression system for any malfunction.
Review 5: Battery-Powered Alarm Installed Above Junction Box
Your first alert 10-year smoke alarm must never be installed on top of a junction box if it is battery-operated. Installing them in a junction box causes false alarms pretty often.
Alarms installed over the junction box have to be electrically operated. Whether it’s any combination like gas, CO, or any smoke alarm.
Plus the alarm unit shouldn’t be connected in the same line with a lot of current loads. It causes false alarms. Rather something like an EST3 fire alarm panel would be a good choice.
If all the above scenarios are not the cause, then it’s probably had a malfunction. Nevertheless, you should consult a professional fire alarm technician.
