How to Stop Your Home Security System from Going Off: Most home security systems work great to keep your home safe. But sometimes, they can go off unintentionally. Here’s how to stop your home security system from going off.

Check the Batteries

One of the most common reasons why a Brinks System can go off unexpectedly is because of the batteries. Without adequate batteries, your Brinks System won’t be able to function properly. It’s important to check the batteries from time to time to ensure that the system is up and running correctly. In this section, we will discuss the steps to take to ensure that your Brinks System runs smoothly.

Replace the batteries in the control panel

Replacing the batteries in your home security system’s control panel on a regular basis is one of the easiest ways to ensure that it won’t go off by mistake. Batteries don’t last forever, and if you’re using the same batteries for too long without replacements, they can start to lose their charge or become weak which could cause them to trigger false alarms.

The frequency of replacement will depend on the type of batteries you’re using, as well as how often your system is activated. most manufacturers suggest changing them at least every six months. It’s always best to replace all the batteries at once, as differing new and old battery levels can create an imbalance in power and also set off false alarms.

Be sure to always use fresh and quality batteries when replacing them. Never mix old and new batteries in the same slot – this can lead to a decrease in performance or even prevent the system from functioning at all! If you’re unsure which type of battery is right for your home security system’s control panel, it’s best to refer to the manufacturer’s instructions that came with your device or contact their customer service team for help.

Replace the batteries in the sensors

One of the main reasons home security systems can be triggered is due to low or dead batteries in the sensors. To ensure that this doesn’t happen, it’s important to regularly check and replace the batteries in all sensors.

The majority of wireless and hard-wired security systems use either lithium or alkaline batteries. Alkaline batteries should be replaced every one to two years, while lithium batteries have a much longer life expectancy of up to five years. However, even if you’re using lithium batteries, we recommend replacing them every three to four years for optimal performance and system reliability.

When replacing the old batteries with new ones, keep in mind that mixing different types or brands of batteries may not work for some systems. It is best to consistently use either alkaline or lithium batteries and never mix them with other battery types. Additionally, it’s important not to allow unauthorized access into your home security system by closely monitoring who has a key and watch who is entering your home as you may be away and unaware when someone tampers with your system.

Test the system after replacing the batteries

After you’ve replaced the batteries in your home security system, you will need to test the system to make sure it is working properly. This can be done by arming and disarming your security system panel, as well as testing any motion detectors or doors/window contacts that may be installed.

Testing the system will also help ensure that when the system detects an incoming intruder, it will pick up on their presence accurately and alert you immediately. When testing the system after replacing batteries, make sure to take extra steps such as covering door windows with paper or cloth before activating any motion detectors and performing other tests, since these can set off alarms even when there is no actual disruption in security. Then arm, disarm and otherwise activate the sensor to make sure all devices are operational. Place a hand near door windows and move slowly throughout the area so that if an alarm is tripped during tests it will quickly stop afterwards without alerting anyone nearby.

Check the Sensors

One of the most common causes of security system false alarms is faulty or damaged sensors. If your security system is constantly going off, it’s essential to check your system’s sensors for any dust, dirt, moisture, or damage. Making sure the sensors are properly maintained and cleaned will help reduce false alarms and ensure your system is working as it should. Let’s look more in detail at how to check and maintain these sensors.

Check for any obstructions in the sensors

Ensuring that any obstructions or outside influences aren’t causing your home security system to go off is essential for peace of mind and avoiding unnecessary false alarms. When first installing the sensors, and in between periodic check-ups, it’s important to identify and assess any movement by rodents and other animals that could inadvertently cause a false alarm.

Additionally, improper placement of the sensors can also create problems which will lead to false alarms. Sensors should be placed away from air vents or direct sources of heat, as well as any areas that may have frequent activity like in doorways or hallways leading to busy areas such as a kitchen. Stronger signals may also be triggered due to too much dust collecting inside the sensor lens which will affect performance. It’s important to assess all of these factors regularly to ensure your system is always functioning correctly.

Every home security system will have different types of motion detectors available such as infrared (also known as PIR) or ultrasound detectors which operate in different ways with unique check-up requirements. To help combat false alarms, dual technology sensors can be used on door/window openings; this type of sensor utilizes two detection technologies – such as passive infrared/microwave – working together for 99% accuracy rate when triggered by a burglar entering an area or dwelling unit. It’s important to familiarize yourself with your specific systems specs and investigate the individual needs for each sensor type available for optimal efficiency.

Check the sensitivity settings of the sensors

An important step in preventing false alarms is to check the sensitivity settings of your home security system’s sensors. The last thing that you want is for a sensor to be ‘too sensitive’, causing it to detect motion or other triggers when it shouldn’t.

If you have this type of sensor in your system, there are a few things that you should know about its sensitivity settings. Firstly, adjust its setting so that any movement from normal everyday activities such as opening and closing windows or doors don’t trigger a false alarm. In addition, remember to account for any potential changes in the environment such as temperature changes which may affect how it responds to certain stimuli.

Another tip involves making sure that pets or small objects such as helium balloons won’t set off the alarm when they move about the house. This can usually be handled by adjusting the distance at which the sensor will detect motion or other triggers. Keep in mind though, if you have large pets, such as dogs and cats above 12 kgs in weight running around the house they may still trigger a false alarm if they come too close to one of your sensors!

Clean the sensors to remove any dust or debris

In some cases, dust, dirt and lint can build up on the sensors which could be causing false alarms. In order to avoid this from happening, it is important to clean the sensors by washing them with mild soap and water once a week. If this doesn’t solve the issue, it may be necessary to remove any objects placed near the sensor that could set off an alarm. This can include items such as curtains or furniture that may have shifted near the sensor’s area of coverage. Additionally, checking for any structural shifts in your house may be needed as movement in walls or foundations can also cause false alarms. Objects such as nearby fans or heaters that produce a lot of vibration should also be taken into consideration while cleaning your sensors. After making sure your sensors are clean and free of debris and other potential triggers, try testing out your system before using it again to ensure it will now function properly.

Check the Wiring

If you keep hearing your home security system going off for no reason, it could be due to faulty wiring. You should have an electrician come in and check the wiring to make sure that everything is working correctly. Checking the wiring is the first step in determining what the cause of the false alarms is. After the wiring has been checked, other causes that could be causing the system to go off can then be investigated.

Check for any loose or disconnected wiring

It is important to ensure that your wiring is connected correctly, as any loose or disconnected wiring can cause false alarms. Look for any wires that may be pulled out of their connections, frayed pieces of wire or cuts in insulation which might result in the alarm being triggered prematurely. If you cannot see the wiring underneath your security system, carefully unplug it and inspect each individual wire carefully for signs of damage or disconnection.

If you find a loose connection or other issue with the wiring, make sure to replace it immediately – if necessary, enlist help from a qualified electrician. It is advisable to cover exposed wires with electrical tape and check the batteries regularly for signs of wear and tear.

Ultimately, making sure your home security system’s wiring is firmly connected and free from sources of interference will help eliminate numerous false alarms over time. Check the batteries regularly to ensure they are in good condition.

Check the System Settings

To prevent your home security system from going off unexpectedly, it is important to Analyze the risks and check the system settings. Ensure that the settings are appropriate for your home and that they are accurate. Be sure to review the sensitivity settings, the entry delay times, and any other settings that may cause false alarms. Additionally, double check that any motion sensors or door/window sensors are properly installed and that they are in working order.

Check if the system is set to “chime” mode

When trying to stop your home security system from going off, it is important to first check its settings. One setting that can sometimes cause false alarms is if it has been set to “chime” mode. In this mode, an alert will sound every time a door or window opens. This is typically used when you are trying to warn people they are entering a secure area without triggering an alarm.

If your home security system has been set to chime mode, the alarm will sound any time the doors or windows open and close. To turn chime mode off, you will need to go into the control panel of your security system and adjust the settings or change it back to “on” mode. Once you have made this adjustment, any future false alarms should be prevented from occurring as long as all of your doors and windows are closed securely.

Check if the system is set to “instant” mode

A large percentage of false alarms can be traced back to security system settings. To ensure that your home or business doesn’t enter a state of false alarm, it is important that you check the settings for your security system and make sure they are set to “Instant” mode.

In Instant mode, sensors attached to motion detectors, windows and doors will respond instantly when activated by a protected area being breached. When combined with the proper setup and other control features such as entrance delay, verbal commands and silent entry notifications, Instant mode ensures that any unauthorized entry is properly detected and responded to in a minimally disruptive manner. This can help save you money on service calls while also giving you peace of mind knowing that your home or business premises are safe from unwanted intruders.

Check if the system is set to “delay” mode

If your home security system is set to “delay” mode, it will give you a certain amount of time (20-60 seconds) before triggering an alarm. Delay mode is designed to give you time to enter the premises and disarm the system. If your system doesn’t turn off after this time period, this means that it is not set to “delay” mode.

To check your system settings and determine if it is set to delay mode, consult your user manual or contact the manufacturer or support team for assistance. It is important that you understand how your home security system works and how long you have before an alarm will be triggered. Additionally, if the delay period isn’t long enough for you or you find yourself always running out of time, ask how long can be adjusted so that it better matches your needs.


If your home security system is going off randomly or too frequently, it can be very frustrating. But don’t worry, there are a few simple steps you can take to troubleshoot the issue. This article will help you identify the source of the problem, and offer tips and tricks to help you get your home security system back on track.

Contact the manufacturer’s technical support

If you have followed all the steps above and your home security system is still going off that it might be time to contact the manufacturer’s technical support. The technician can take you through a few more steps that may help you resolve the issue.

The manufacturer can also provide troubleshooting advice associated with their specific product. They may suggest checking your wiring, replacing batteries in remotes or sensors, or even reprogramming the system. Depending on the brand and model of your home security system, there may also be troubleshooting guides available online or user manuals to reference for guidance.

If none of these approaches solve your issue, then it’s likely that professional repair is necessary. Likely either a technician from your security system provider will need to come to your home and inspect the wiring and sensors, or perhaps certain components will need to be replaced (this is usually true for older systems). Either way, contact a customer service representative from your company to discuss what option is best for you.
