There’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.
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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
