Why Is My Alarm Hub Beeping?

When your house alarm begins to beep intermittently, there is a fault somewhere in the system. 

Most often, this is due to a loose sensor or a faulty battery. Household alarms have a display screen on the main control panel that indicates which sensor is causing the beeping. 

To fix a house alarm system that keeps beeping sometimes requires bypassing the zone that the sensor is in altogether for a short time. 

Because of the many different alarm systems on the market today, it is a good idea to have your owner's manual handy.

There are many possible reasons why a Fire or Carbon Monoxide alarm could be beeping. The most important thing is not to ignore this, as they are warning signs of danger in the home or that a warning needs maintenance.

Alarm Beeping

A Smoke Or Heat Alarm Is Emitting A Full Alarm Sound:

If the alarms are sounding, there may be a fire present. You should evacuate the property and be sure there is no fire before returning. 

If in doubt, always assume there is a real fire present and take the necessary action.

If there is no fire present:

  • Find the alarm with the red light rapidly flashing. Press its ‘Hush’ button to silence. If that does not silence it, clean the notice using a vacuum. Wait for 10 minutes, and the issue should be resolved.
  • Are there any cooking fumes or steam around this could be the reason behind the alarm fault – if so, it may be incorrectly sited or the wrong sensor type for the area

A regular single beep from a smoke or heat alarm: 

  • If it is a regular single beep (approximately once every minute), then the battery may be running low, and you may need to change the battery in the alarm. This is relevant for the 140RC Series alarms.
  • If the green power light is off – contact your installer or an Expert Installer to check wiring & connections.

The Irregular Beep From A Smoke Or Heat Alarm:

  • Clean the alarms
  • There may be an issue with the wiring – contact your installer or an Expert Installer to check wiring & connections

A Carbon Monoxide Alarm Is Sounding: 

  • There is likely to be Carbon Monoxide present. Turn off any gas appliances, open windows and doors and leave the property.
  • Ring the emergency number of the gas/fuel supplier
  • Do not enter the property until the alarm has stopped.
  • If the alarm contains AudioLINK – Once the alarm has stopped activating and it is safe to enter the property, extract a report to identify the details of the incident.

 Regular Single Beep Or Irregular Beep From A Carbon Monoxide Alarm:

  • If the green light is off- contact your installer or an Expert Installer to check the wiring & connections.
  • If the alarm contains AudioLINK – extract a report to identify the details of the incident.

Six Ways To Fix Alarm System Beeping After Power Outage

Most security alarms have built-in features that help notify the owners if someone is trying to break into their home. If anyone who is not an authorised user tries to disarm the alarm, then you’ll get a notification on your phone as long as you’re using a smart alarm system.

Similarly, if someone is trying to disarm your system by removing the power, it will start beeping, and usually, burglars will get scared and leave your house. However, having a simple power cut can also cause similar problems. So, if you have the same issue, these steps might help you.

Contact Service Provider

The easiest thing to do in this situation would be to contact your service provider and ask for instructions. That way, you’ll get professional help and will get the beeping to stop immediately. 

Most of the alarm systems today come with a monthly subscription. Professional support is available for users, and you can ring up the company number if you’re having issues with your alarm system. So, in case of any problem, just get in touch with a professional, and you should be able to get the Alarm system to stop beeping.

That is the main reason why customers are willing to pay subscription fees for security services. The beeping on the Alarm system is there to alert owners that someone is trying to disarm their security system. So, it is a safety mechanism that can inform users if someone attempts to tamper with the alarm by cutting off the power to the system. The backup battery will take over, and you will start hearing a beeping noise from the alarm system. Ask your service provider for the specific procedure depending upon the type of alarm system you have installed in your home.

Disarm System

In most of the newer alarm systems, you can get the being to stop by simply disarming the alarm system. But before that, you will need to make sure that the alarm can draw power from the outlet and is not working on backup batteries at the moment. After ensuring that the power supply is working correctly, you can use the control panel to log in to the Alarm system using the security code. After that, just click disarm from the controls, and that should get the beeping to stop.

If the beeping does not stop at this point, then we believe that there is something wrong with the outlet, and the alarm is not able to draw power. This is why it keeps beeping to inform users that the administration has been cut off and the device is running on backup power. To ensure that the control whether or not the power outlet is working correctly, you can plug in some other gadget and see if that turns on. If it doesn’t, then you should switch the power outlets and plug in your Alarm System into a news outlet.

Silence Feature

After ensuring that no one has tampered with your device and the only problem was a power outage, you can go ahead and use the silence feature on your Alarm system. That will get the beeping to stop immediately, and then you can relax. Usually, there is a dedicated button that you can find on the corner of the keypad. But if you’re using an old Alarm System, then chances are that you don’t have the silence feature on your alarm. In that situation, you can follow the troubleshooting method mentioned below.

Reinstall Batteries

For the older variants of the Alarm system, if the beeping does not stop after disarming the alarm, you should take out the batteries from the notice and then put them back inside. Turn on the warning to check if the problem persists. The beeping noise can also mean that the backup batteries are drained, in which case you should replace the batteries with a fresh pair, and that should get the beeping to stop. However, it is still better to ask a professional to guide you so that you don’t compromise the safety of your home. So, make sure to consult a professional before removing batteries from the system.

Make Sure A Risk Isn’t Present.

Check your security panel and other sounding devices (i.e. smoke and carbon monoxide detectors) to ensure that the beeping is not caused by a legitimate risk, such as an intrusion, fire or carbon monoxide leak.

If you think the triggered alarm could have been caused by a severe threat, confirm with your alarm company’s monitoring centre or contact the appropriate authorities immediately.

Check Wiring

If the above has not worked, and beeping persists, see if your system’s wiring is corroded. You can do this easily with a voltmeter, a tool used to measure electrical potential. Voltmeters are relatively inexpensive and accessible at your local hardware store.

Do this yourself only if you have electrical experience. If you don't, hire a professional electrician.

How To Stop An Old Alarm System From Continuously Beeping

Are you tired of that annoying beeping sound? We don’t blame you! We’ll help you troubleshoot this frustrating problem.

The first thing you’ll want to do is go to your alarm keypad. If you know the code to disarm the alarm, enter it and see if that stops the beeping sound. If you don’t know the code, look for buttons labelled “clear” or “reset” and press those.

Note: You can also try pressing the “*” or “#” keys, as these buttons often silence the keypad sounder. However, DO NOT press those keys simultaneously because, on many systems, that combination is used as an emergency signal to dispatch police.

If the beeping sound persists or starts again shortly after you put in your code, you may have one of the following issues:

  • Loss of power
  • Low or dead backup battery
  • Phone line connection issue

Loss Of Power

Alarm systems need electricity for everyday operation, so if your alarm isn’t getting any power, it will alert you to let you know something is wrong.

Sometimes alarm keypads will display an “AC loss” or “No AC” signal if it’s lost electrical current. If this is the case, the beeping noise is meant to alert you that your system is now running on backup power (typically, this will be batteries).

If you notice that other appliances or electrical fixtures in your home aren’t turning on, that could confirm you have this issue.

Solution: Check The Transformer

Every alarm system has a transformer that plugs the security system into a standard AC wall outlet for power (see above).

If that transformer/outlet connection is loose, though, your system will lose power (and start beeping to let you know). Check that the transformer is securely connected to the wall outlet.

If the connection is secure, the outlet itself may be faulty, or the circuit breaker it lives on may be tripped. You’ll need to contact a professional to determine what the issue is and resolve it.

Low Or Dead Backup Battery

Most alarm systems have a backup battery that kicks in if the power ever goes out. When the battery is low or dead in an old alarm system, the system will start beeping to alert you that it needs to be replaced.

If your battery is low, it will either need to be disconnected or replaced. If you don’t use your old alarm system anymore, we recommend disconnecting the battery and terminal, so the beeping sound doesn’t come back.

Solution: Replace Or Remove The Battery

Follow these steps to replace or remove your battery:

Step #1: Locate The Alarm Control Panel

The control panel is usually located in a closet, utility room or basement. Look for a putty-coloured, rectangular box with the alarm manufacturer’s name on it.

Step #2: Open The Control Panel

To open the panel, try opening it with a screwdriver. Some boards require a key or security code to be opened. Check the top of the box for a taped key. If you don’t have the key or don’t know the code, you’ll need to contact a professional to help you disassemble the panel and remove the battery.

Step #3: Identify The Battery

If you can remove the panel yourself, you’ll see a small, black, square-shaped box connected to a circuit board. This is the battery. If you are replacing the battery, take note of what type of battery it is to purchase a replacement.

Step #4: Disconnect The Battery From The Circuit Board

You’ll see two wires connecting the battery to the circuit board. Start by gently removing the black wire from the negative terminal on the battery. Next, remove the red wire from the positive terminal.

Safety tip: Be careful that no metal objects touch the battery terminals or wire connectors.

Now that the battery is removed, you can reconnect a new battery or leave your system 


To Reconnect A New Battery, Do The Following.

Once you have a replacement battery, you can reconnect it to the circuit board, starting with the red wire (positive terminal). Then, reconnect the black wire (negative terminal) to the battery.

After the battery is connected, go to your alarm keypad and see if that got rid of the low battery notification. If the warning persists, you’ll need to contact a security system professional for further troubleshooting. This may not be an instant fix; please allow up to 6 hours for the panel to recognise battery change.

To Leave The System Disconnected, Unplug The Transformer.

If you choose to leave the old alarm system disconnected, you’ll also want to unplug the transformer. (see image above of the transformer). If you open the transformer, your alarm system will no longer receive power, which should stop the beeping sound for good.

Phone Line Connection Issue

A problem with your landline could be what’s causing your alarm to beep. If you have a monitored security system and use landline monitoring (vs cellular), it could be beeping due to a connection issue with the phone line. The simple way to confirm a phone line issue is to pick up the phone. If the line is dead, this is your issue.

Solution: Contact A Professional For Assistance

Since fixing a faulty phone line can be complicated, we recommend contacting a security professional to help you troubleshoot the connection issue. You may also need to get your phone service provider to see if the problem is something on their end.

Keep in mind that landline monitoring is a less secure way to keep your home monitored. That said, your safest option is to have a professional upgrade your security system to cellular monitoring instead of simply repairing an outdated system.

Step 1

Go to the alarm keypad and press any key on the keypad with your finger. This stops the beeping for a brief time. Look at the display screen on the keypad. The display screen indicates where the trouble location is in most instances.

Step 2

Find the sensor that the display panel indicates is faulty. Check the sensor to ensure that the sensor and the sensor contacts are secure. If the sensor or communication is loose, they will not make a good connection, and you will receive a faulty beep.

Step 3

Tighten any loose screws securing the sensor or contact a Phillips-head screwdriver if your system uses screws. Some systems use special epoxy glue to hold the sensors in place. If that's the case for your plan, call your alarm company.

Step 4

Remove the screw securing the cover to the sensor with the Phillips-head screwdriver. Pull the battery out of the sensor and install a new battery. Place the cap back on the sensor and secure it with the retaining screw.

Step 5

Go back to the alarm control panel and check the display screen. If the sensor is no longer troublesome, the net will display "Ready." If not, bypass the sensor temporarily and call your alarm company for service.

Step 6

Enter your security code and press the bypass key. Some alarms will differ on bypass sones, so refer to your owner's manual for specifics on your notice. Generally, you enter a two-digit number that identifies the one you wish to bypass. This will stop the beeping until the alarm company services the system.
