SimpliSafe smoke detectors are reliable for detecting smoke in your home, alerting you to potential danger.

However, the beeping sound sometimes indicates a low battery or device malfunction.

Alright, let’s take a closer look at the solutions.

SimpliSafe Smoke Detector Beeping – 8 Easy Fixes

There are multiple ways to address the beeping problem.

We arranged them in increasing complexity for a more systematic approach.

#1: Check the Battery and Replace It

If you see no signs of smoke or fire in your home but your SimpliSafe smoke detector keeps beeping, it’s likely due to a low battery. The average lifespan of the battery is usually one year.

You need to replace it when your device starts beeping every minute without any light indicator. 

To check and replace the battery, follow these steps:

1. Twist your smoke detector counterclockwise to remove it from its bracket. 
2. Open the battery compartment on the back of your device. 
3. Remove the old battery.
4. Insert a new CR123A lithium battery.
5. Close the battery compartment. 
6. Twist your device clockwise to reinstall it to its bracket. 
7. Press and hold the test button for three seconds. 

Tip: Schedule battery checks monthly to ensure your smoke detector remains operational.  

#2: Inspect the Test Button and Make Sure It’s Released

The test button triggers an alarm sound and red light to check if your SimpliSafe smoke detector is working properly.

Pressing it while inserting or removing the battery gets the button stuck due to dust or debris. 

To fix this, check the test button and ensure it is released.

Here’s how to do this:

1. Remove the smoke detector from its bracket. 
2. Locate the test button on the front of the device.  
3. Check for dirt or obstruction around or under the button.
4. Use a soft cloth or cotton swab to clean the area.
5. Press and release the test button several times to ensure it’s not stuck. 
6. Reinstall the smoke detector to its bracket. 
7. Press and hold the test button for three seconds to test your device. 

Note: Conduct this test regularly to ensure your smoke detector is working. It will trigger an alert to the monitoring center, and you will receive a call to confirm the test. 

#3: Clean Your Smoke Detector’s Sensors

The sensor is a photoelectric device that detects smoke particles in the air.

However, the accumulation of dust, dirt, insects, or other contaminants on or inside the sensor chamber will cause false alarms or yellow light indicators. To fix this, clean your device’s sensors.

Here are the steps to do this:

1. Remove the smoke detector from its bracket.
2. Slide the latch on the back of your device to open the sensor chamber.  
3. Use a soft brush or vacuum cleaner to remove dust or debris.
4. Close the sensor chamber.
5. Reinstall the smoke detector to its bracket.   
6. Press and hold the test button for three seconds.

If the smoke detector stops beeping and flashes green, you’ve successfully cleaned the sensor.

If it still beeps and flashes yellow, proceed to the next solution. 

#4: Check Your Smoke Detector’s Expiration Date

The average lifespan of a smoke detector is about 10 years, after which it loses its sensitivity and reliability.

If your SimpliSafe smoke detector is expired, it will beep intermittently and flash yellow. In this case, promptly replace it for your home’s safety.  

To check your device’s expiration date, follow these steps:

1. Remove the smoke detector from its bracket.
2. Locate the label on the back of your device.
3. Look for the manufacture date.
4. Add 10 years to it to get the expiration date. 
5. Compare the expiration date with the current date. 
6. If it has passed, replace the smoke detector with a new one. 
7. If not, reinstall the smoke detector on its bracket. 

Note: Mark the expiration date on your calendar or set a reminder to replace your smoke detector when you get to that date. 

#5: Restart Your Smoke Detector

Another possible cause of the SimpliSafe smoke detector keeps beeping problem is a software glitch.

This usually happens due to a power surge, voltage fluctuation, or a firmware update. To resolve the issue, restart your smoke detector.

Here’s how to do this:

1. Remove the smoke detector from its bracket.
2. Open the battery compartment.
3. Remove the battery and wait for 10 seconds.
4. Reinsert the battery while holding down the test button.
5. Release it after hearing three beeps.
6. Close the battery compartment. 
7. Reinstall the smoke detector to its bracket. 

Tip: Schedule maintenance to keep your smoke detector operational. Maintain records of when you conducted the restart, as they are useful for tracking your device’s performance. 

#6: Inspect the Wiring on Your Smoke Detector

Some SimplisSafe smoke detectors are wired to your home’s electrical system, meaning they are connected to a power source and a backup battery.

Damage to the wiring and loose connections trigger false alarms and low battery alerts, causing the beeping issue. 

To inspect the wiring on your smoke detector, follow these steps:

1. Cut your smoke detector’s power supply at the circuit breaker or fuse box. 
2. Remove your smoke detector from its base. 
3. Disconnect the wiring harness from the back of the device.
4. Check for signs of damage, corrosion, or fraying.
5. Use a wire stripper to strip off about half an inch of insulation from each wire.
6. Use a multimeter to test for voltage or continuity. 
7. If there’s no voltage or continuity, replace the faulty wire with a new one.
8. If there is voltage or continuity, reconnect the wiring harness to the device.  
9. Reinstall the smoke detector to its bracket. 
10. Turn on the power supply. 
11. Press and hold the test button for three seconds.

Note: Don’t attempt this solution if you’re unsure how to execute it safely. Consult a licensed electrician instead. 

#7: Look for Any Sources of Smoke in Your Home

If there are no problems with the battery and the hardware, the beeping could be a legitimate alarm.

Your SimpliSafe device has detected actual smoke or fire elements in your home, meaning it’s doing its job alerting you of potential fire hazards. 

Important: A beeping smoke detector with a red light signals smoke or fire in your home. Do not ignore this fire warning. 

To look for sources of smoke, follow these steps:

1. Check for any visible signs of smoke or fire. 
2. Inspect your appliances, outlets, and wiring for overheating, sparking, and odd odors. 
3. Examine your cooking appliances for smoke or fire. 
4. Check your heating equipment for signs of smoke or malfunction. 
5. Inspect your HVAC system for smoke and unusual odors.  
6. Monitor candles and open flames in your home. 
7. Look into your closets and cabinets for hidden sources of fire.
8. Check your electrical panels for signs of overheating and electrical issues. 
9. Go room to room for a thorough inspection. 
10. Pay attention to any fire or sound alarms. 

Tip: If you find any source of smoke, ensure your home is well-ventilated to disperse it. Evacuate your home immediately and call emergency service if you can’t safely control it. 

#8: Optimize Your Smoke Detector’s Position

Improper position is another reason your SimpliSafe smoke detector is beeping. If your device is too close to a heat source, ventilation system, humid area, or dusty corner, it will cause false alarms.

You need to optimize its position to enhance performance and sensitivity. 

Here are the guidelines to do this:

• Install your smoke detector at least 4 inches from the walls and ceiling.
• Avoid windows, doors, fans, air conditioners, vents, or heaters. 
• Don’t install it in your kitchen, bathroom, basement, attic, and garage. 
• Avoid areas with high humidity, temperature fluctuations, and dust.
• Install it at least 10 feet away from cooking appliances.
• Install it at least 3 feet away from any fluorescent light. 

If you need to reposition your SimpliSafe smoke detector, follow these steps:

1. Remove the smoke detector from its bracket.
2. Choose a new location that meets the guidelines above. 
3. Install a new bracket on the ceiling or wall. 
4. Reinstall the smoke detector to the new bracket. 
5. Press and hold the test button for three seconds.
