Guest Post By: Shaon

Before you figure out how to fix your security alarm, you need to find out what is wrong with it first. The good news is, most of the issues with home security alarms are easily diagnosable if you have the right tools. So, most of the time you won’t have to hire the experts to do it for you. And for that reason, I recommend having the best fluke meter for HVAC. You will need it to figure out a faulty system, after which you can know what to do.

What are the most common security alarm problems?

A faulty security alarm can make your life so miserable. You can keep jumping up to false alarms and fake alerts. This can make it difficult to differentiate between wrong calls and an actual security breach. However, the worst-case scenario is a failed alarm system. This means you won’t be alerted in case of break-ins despite having installed a security system.

Anyway, some of the most common issues with home security alarms include:

• Electric/wiring problem
• Faulty backup battery
• Sensor problems
• Wear and tear

Keypad/button problems

Most of these problems can be caused by several different issues and factors. In most cases, it is either an installation error that erupts later. Or, it could be a case of your alarm system wearing out. If both of these cases don’t apply, then you need to check your system and find out the root of your problem. Remember, even a faulty door lock or an open window in your house can trigger a false alarm. All these must be put into considerations and dealt with.

But if you feel everything is in place but your alarm system is just failing due to technical error, then that’s when your handy techniques will be required. Some of the ways to help solve your alarm security system have been discussed below. Keeping reading to find out how you can solve your alarm issues without hiring an expert.

System check-up

The first and most important step in repairing your faulty alarm system is beginning by checking the entire system for failures. At this point, your HVAC multi-meter will be your greatest tool. It will help you to identify any faults with your electrical system. In case there is an issue with the connection or power systems, you will be able to figure it out. Funny enough, sometimes you come to find out the issue is some loose screws or a detached wire. All of which are very easy to correct.

Repair Equipment

Once you figure out where your nightmare is coming from, list and assemble all the required repair tools. My advice all handy homeowners, both professionals, and hobbyists is that; always keep your toolbox up to date. Ensure you have all the basic maintenance and repair tools you need to run your home. Some of these essential tools include:

• Wire cutters
• Wire strippers
• Terminal crimpers
• Screwdriver set
• Digital multimeter
• LED flashlight
• Tone and probe tracer

There are a lot more than just this list above. However, having most of the essentials mentioned above will get you started and most likely help you solve the basic alarm faults. Also, you have to know that your screwdrivers so well because the alarm system requires a couple of special screwdrivers. That is why you need to have the whole set. Also, consider having an electric screwdriver.

Replacement parts

Like any other electrical device, your alarm system is made up of different parts that work together to function as a single device. If you open it up, you will be surprised by how much junk is in there. Like I mentioned earlier, you can either find fault in the wiring, backup batteries or any of the other parts. Therefore, after your system diagnose you will be able to know the exact part to mend or replace. Ensure your power system is switched of before commencing on any replacement process. Also, tighten back the screws properly after replacing any part of your alarm system.

System Upgrades

Lastly, apart from breakages or system damages, your alarm system can malfunction when it’s outdated. If you are using analog or old alarm systems, you should consider replacing or upgrading your system. In most cases, after using the same system for a year, it can just stop working. At this point, even basic repairs might not solve its problem.


Put in simple terms, fixing your home security alarm might not be as easy as it sounds. But there is always a way around it. The question is, are you a professional or a DIY hobbyist? Either way, all you need are diagnose HVAC tools and the right alarm repair tools. Follow our guidelines and save a lot of bucks by handling the repair job yourself.
