What Causes Static On Intercom Systems?

gate intercom installationStatic is not an uncommon issue with intercom systems. It can be caused by almost anything but the good news is, some causes are easy to fix on your own. Read on to know the possible causes of static on your intercom system.

  • Interference

It’s almost strange that an intercom which is a closed system can have issues with interference. To know if interference is your culprit, check your environment for the electrical appliances around. Do some testing by disconnecting and reconnecting the appliance or appliances found to see if the static stops and starts. If the appliances are responsible for the interference, then check if your equipment is properly grounded.

Another source of interference can be a radio broadcasting near the system. The radio frequency may interfere with your intercom system, but this particular issue dissipates as soon as the radio moves away.

  • Equipment

Your intercom system may be its own problem. Sometimes as the intercom ages, its parts can develop wear. So the wiring may start to show the signs by causing static. Aside from age, moisture, pests, or damage in the intercom’s wiring can lead to static on the system.

In this way, an intercom can help you discover even bigger problems in your electrical connection. Problems with the connection where the intercom is plugged can manifest as static. If left unattended, the issue could damage the intercom. Fixing the circuit can help clear up the static.

Static is only one of the issues an intercom system can have. Others include humming noises and power supply failures.

While using some tips above to fix the static problem might be sufficient, others will require an intercom repair professional. You can contact a professional to explain the problem and get insight on if it can be fixed or if your system probably needs a replacement.

3 Common Intercom System Repair Issues

intercom power issuesIntercom systems in homes or any building for that matter have specific functions that make life easier. They improve security, save time, and are invaluable for when someone needs help in the home or building.

Despite their great functions, intercom systems are not without a few setbacks. There are common intercom system repair issues that owners sometimes have to deal with. Learn more about the 3 major culprits below and how to solve them.

  1. Static

On our list of 3 common intercom system repair issues, static is probably the most common of all. Static can be heard from the microphone or speaker and its causes include;

  • A bad connection developed due to old parts of the intercom system
  • Damage or faults in the intercom system such as a loose wire or bad switch.
  • Power overload or short circuit
  • Interference
  • Poor power connection

While it’s easy to handle static caused by a poor power connection or interference, others will require the expertise of an intercom repair professional. Trying to DIY the problem may only cause further damage. It’s also possible that some causes of static indicate a bigger problem with the system. Your intercom repair professional will inform you if a repair or replacement is the best option.

  1. Power supply failure

A power supply failure can easily translate to your intercom system not working at all. Power failures are part of the bigger problems other issues like static may indicate. Thankfully, power failures don’t just occur at once. They send warning signs at the beginning with either the static or a humming sound. Your intercom repair expert will be able to point this out when they take a look at the system.

  1. Humming noise

Humming sounds from your intercom system can be as annoying as static. Causes of a humming sound often include;

  • An underlying or bigger problem such as power failure
  • Faulty wiring or connection

Some owners try to live with the humming sound or ignore it and this is a wrong and dangerous approach. When the problem gets worse, repairing the intercom system might become impossible. Call an intercom repair professional if you observe these humming sounds.

What you can do

  • Although calling an expert is your best option, there are steps you can take to solve or reduce some of these common issues.
  • Check the troubleshooting guide in your intercom system’s manual for directions on the problem.
  • Check that the power indicator on the system is lit. If it’s not, check the plug. It’s possible the adapter unit may not be plugged in properly or the power socket being used is defective. Change the socket or plug in the adapter unit properly to fix this. If none of this works or the power unit seems okay, loose wiring may be the problem.
  • For dealing with a humming sound, interference from other appliances like dimmers and fluorescent light switches may be to blame. Try switching off the lights or other equipment to eliminate the hum and single out the source.

Security System: Professional vs. DIY

security system repairStatistics say there are about 2 million burglaries in the United States each year. Shocking, but not quite when you know that only 17% of homes in the country have any type of security system. Burglars get into homes through various entry points and with no alarm or security systems to deter such activities in your home, it’s easy to become a statistic.

Knowing how critical the situation is, you have two major options for security systems. These are professional or DIY installations. The quickest thing most people think about these home security options is that DIY installations are cheaper and easier. While this isn’t wrong, it’s not advisable to choose between both options using price alone. Read on as we break down the pros and cons of each.

Professional Security System

A professional security system provides benefits that outweigh the initial costs. You can get more from the installation and home security systems installed. Here are the pros associated with a professional security system;

  • You can get indoor and outdoor security cameras and sensors for every door and window regardless of the size of your home.
  • There will be a scheduled appointment with a professional installer to explain your options.

  • An experienced technician on site can troubleshoot problems and ensure the system is efficient.
  • The technician can walk you through everything, including more suggestions for home security and using the app.
  • The technician can conduct a security assessment.

As sweet as these pros sound there are cons that might stand out for you;

  • There are installation fees to be paid
  • You have to make the time to let a stranger into your home.
  • Professional security systems often require contracts.
  • This option may not work for renters or tenants.

DIY Security System

Going DIY is not without its perks. Here are the pros that make this an appealing option for many homes;

  • No installation fees but higher up-front equipment costs
  • No interruptions in your schedule and you control your time for the installation.
  • Wires are not involved, and this works better for most renters.
  • You don’t need to let strangers in your home.
  • No contracts required.

Intercom Issues: Power

Intercoms are a valuable addition to the home, but when intercom issues such as power come up, they reduce the functionality of the device. Your first thoughts may be to call on an expert or throw the faulty intercom out for a new one.

However, simple troubleshooting tips can help you get ahead of the problem and get your intercom working perfectly in no time. It may surprise you to find that the problem is nothing more than a defective outlet or improperly plugged adapter.

The best part is, you don’t need to be an expert on electronics to use these troubleshooting tips and solve your intercom power issues.

STEP 1 – Take a look at the manual.

Electronics like your intercom system come with a manual. The manual is often simple enough to understand, and it gives directions on various issues that concern using, installing, and troubleshooting your intercom system. Look to the troubleshooting section and follow the directions to see if you can find the problem.

This troubleshooting section usually includes information on identifying the source of various problems with the intercom and solving them too. If the manual doesn’t help get everything back to normal, then we can move on to step 2.

STEP 2 – The power.

Power is vital for your intercom system to work, and most times when your intercom system seems damaged, the issue could be nothing more than a simple power problem. First, check the intercom to see if the power indicator is lit. A home intercom system receives power from a 12V DC adapter and it may not be plugged it the right way. Check that the adapter is plugged in and switched on the ON position.

If you have done these and the intercom still won’t work, then there are a few other possibilities. Try plugging the device elsewhere using another outlet. Confirm that these outlets are working with other devices first. Check your electrical panel for any breakers are in the OFF position. You can try switching such breakers on and see if there are any changes.

Most adapters are built with a safety mechanism that kicks in to protect the system from damage during power surges. If the safety mechanism has tripped off, you can restore the system by resetting the adapter.

If none of these work, your device may be faulty and due for a replacement or professional assistance. Contact a local Santa Clarita electrician to come and take a look. Secure Tech can troubleshoot your intercom with ease and recommend the best course of action!

Intercom Noise Problems

gate intercom installationThere’s almost nothing more frustrating than noise problems from your intercom. Intercoms are invaluable for security and communication. Clearly, you purchased them because you recognized their importance. So, experiencing noise problems can cause worry and stress you out.

The thing about such issues is that fixing can go both ways. A good fix can rid you of the problem forever, and a shoddy one can cause the issue to reoccur.

A good fix will comprise knowing exactly what the cause of the noise is and fixing that cause. Sometimes, you may need an expert for this, and sometimes you can do the troubleshooting on your own.

Read on for all you need to know about intercom noise problems.

Prevention First

The best solution you could ever have to a common problem is to prevent it from happening in the first place. Here are tips for avoiding basic problems;

  • High squelch settings on an intercom can serve as protection from interference. But, seeing as this can also be a disadvantage to the operating range, it’s best to set the control to the lowest position that significantly mutes interference.
  • Avoid proximity between your intercom and other wireless systems like a radio transmitter. If such wireless systems come within 10 to 15 feet of the intercom, the receivers can get overloaded and this increases the chance of interference.
  • Ensure that all transmitters have good batteries as weak batteries can generate harmful interference.

Identifying the type of interference

Intercom noise or interference can be from a myriad of causes, and this categorizes interference into types. The following are symptoms that indicate a different type of interference. As stated above, knowing the precise cause is an effective approach to a working solution.

  1. The interference sounds like short bursts of noise or static crashes. Lightning, defective electrical machinery or intermittent arcing can easily cause this. It’s rare and difficult to resolve and known as random interference.
  2. The interference occurs when the wireless transmitter is off. This could be related to squelch problems, and if this is the case, it’s a low-level interference.
  3. If you experience irregular crackling, buzzing, or popping noises when the transmitter is turned on, the problem is an electrical interference problem. The culprits are often electrical equipment like electric motors, lighting, and appliances.
  4. If you experience interference when the transmitter is off AND distortion or noise on the receiver audio when the transmitter is on, turn off other wireless transmitters. If the noise still continues, then there is a direct interference problem which requires quick fixing for the intercom to be useful.
  5. Buzzy sounds or raspy whines that come up when the transmitter is turned on, and also often change their rhythm, indicate digital interference. Culprits of digital interference include lighting controller, computers, and digital delays.
  6. If the interference observed when the transmitter is turned on disappears when other wireless transmitters are turned off, you may be dealing with intermodulation interference.

For each of these types, there are methods to solve them. If none of the above symptoms seems to match your intercom noise problems, consult with your dealer for assistance or reach out here.

Intercom Issues: Noises

intercom issues noiseIntercoms are great for communicating between spaces. They are straightforward enough and a good investment of your time and money. While intercoms may hardly need maintenance, even those installed by the best technicians can develop an issue or two.

One of the most common intercom issues is noise. This noise can occur as static or a humming sound. When this happens, it doesn’t mean your intercom was defective or not installed properly. Usually, identifying the source of the problem helps to choose a solution. Here are the major causes of noise as an intercom issue.

  1. Interference
    Interference can easily affect an intercom when it’s caused by other electrical appliances nearby. To identify if this is the source of the problem check all the electrical devices in the same location as the intercom. Unplug them one at a time and note if the noise stops with any particular appliance unplugged. If you can identify the culprit, then check for grounding of that appliance.

    Another source of interference could be a radio broadcasting nearby. It’s possible if someone or a utility worker is in that proximity with a two-way radio. If such radio is the cause of the interference, you can simply sit tight until the radio moves elsewhere. The problem would stop then.

  2. Power supply

    Intercoms are electrical devices which means they are connected to a source of power. Static or noise caused by an issue with the power connection may indicate an even deeper problem requiring the attention of a technician or electrician. Repairs to the electric connection can also solve this issue.

  3. Equipment

    It is expected that the intercom’s system would wear out with time. In some cases, the equipment getting old and worn out leads to static or noises. This just serves as a sign of the ending lifespan of the equipment. Other factors that influence the reliability of the intercom’s system like rodents, pests, moisture, and so on can damage wiring or parts of the intercom leading to the noise.

  4. When you observe these intercom issues, calling on an intercom repair expert or your previous installer is the best option. It saves you the hassle of the situation, money if a solution can be offered, and time. You can reach out to us for more information or assistance.
