All but one of the blocks of flats I look after have the Videx 8000 series intercoms so I have only ever used this Videx handset with the those. I imagine they could possibly be used on other makes but have never needed to as yet so honestly not 100% sure.
From a safety point, working on it live won't cause you any harm as there is only around 12v DC running to them. However, there would be a risk of damaging the system if any of the wires were to touch / short out. I would advise powering the system down first. There will probably be a fused connection unit (fused spur) somewhere which you would have to remove the fuse from or switch it off, if it's a switched fused connection unit.
Hi. Are panel works - can hear resident, they can hear visit, resident can unlock door - we just can't hear buttons buzz and no buzz sound in flat. This is all 6 flats. Any idea what this can be? We have an Elvox 8202. Thanks
I am not familiar with the Elvox system, however I would guess the problem will be in the call panel next to the door as the buzzers in the hand sets very rarely fail especially all 6. If you look at my very first you tube video, this is a fault which appears to be the same as you describe, but on a Videx panel but may be of some help. Thanks for watching and the comment!
@HWrenMaintenanceServicesLTD thanks for the reply. It's just the buzzer which isn't working. Any idea where the buzzer sound on the outside intercom panel comes from, when you press the buttons? Thanks
Assuming this is similar to the Videx systems, there is a buzzer built inside each handset in the flats / apartments. The call panel at the front door then has a button / switch for each flat number. Pressing this button supplies voltage to the handset buzzer in the flat. These can sometimes be fixed by spraying the back of the button where the contacts are wit some contact cleaner spray. Just a thought, or were you referring to the buzzing which can be heard by the visitor (so they know the door is open) when you press the door open button on your handset in the flat? If so, that noise is actually produced by the electric lock release at the door. If thats the case it could be a faulty electric release or power supply to the electric release.
TBH not sure what that would be. I know videx use a power supply with two outputs, one AC for the buzzer and door release and one DC for the speech. If its the same on your system and the AC side failed you would have speech but no door release but your release is working, strange. Its probably going to need a engineer to have a look at it, without actually seeing it its all guess work from me anyway. Sorry I cant be of any more help than that. When you get it sorted, let me know what it turned out to be.
Great video👍🏻. My problem is buzz working no problem，but when I pick up handset, there's no sound at all, I can't hear visitors voice and they can’t hear me neither, should I change a new handset？
Thanks for watching and the comment. Its pretty hard to diagnose without actually carrying out tests, however the handset would be the cheapest part to replace. The next part it could probably be would be the speech module. I would double check wiring first though as it may simply be a broken / loose wire or two.
I got a slightly different problem. When a visitor presses the button on the intercom for my neighbour the intercom rings on both my door entry phone and my neighbours door entry phone at the same time and vice versa. What could be the cause and the solution? Thanks.
Ive not seen that fault before, but at a guess assuming it hasn't been like that since day one I would expect the fault to be on the call panel. Possibly something mechanical broken inside behind the push buttons shorting both contacts out when pressed or wires from the call buttons shorting out somewhere. I would be looking inside the call panel first.
@@HWrenMaintenanceServicesLTD Thanks for your reply. I really appreciate it. Yeah what happened was we had some construction workers installing insulation to the external walls of the house. They took the intercom off the wall and then put it back on the wall and since they did that my door entry phone is ringing when my neighbours button is pressed. I have told the construction company project manager but he is too busy dealing with other projects.
To me that defo means its a wiring fault in the panel. It will be a simple fix as they have obviously mixed the wires up to the push buttons. At a guess the power supply wires and the wires to the buzzers have been put the wrong way round where they connect to the push buttons which would link out the two buttons on the call side which would give your problem. It is really a job for them to sort out.
Are there any other monitors connected to the system? i.e. if in a block of apartments, other apartments? If others are working then the problem is with your monitor or wiring. If yours is the only monitor then it could be the monitor, or the microphone / speech module at the call panel end. There is always a possibility of faulty wiring but in my experience wiring faults are very rare.
It works for about a month then after that the sounds in the monitor is no longer working. I only used it as a camera. Also this is my second buy the first one also has the same problem.
Sounds strange that it works initially. Possibly been unlucky and had faulty replacements or installed incorrectly? Maybe try another engineer to diagnose it.
Probably rain related. I did have one where the microphone on the external call panel had water leak into it and failed. From memory I think it did still work slightly but extremely quiet / muffled. You might be lucky and may start working if it dries out.
@@HWrenMaintenanceServicesLTD years ago I got job to install 121 intercoms, biggest building in my town. Urmet, digital, three access door control units, with 27' TV integrated on external wall for nubmers and caller id names. Everything went well, but at the end there was ONE LAST IDIOT in that building that I couldn't get to change his speaker in his apartment. I had to postpone 1 month to write a check to get the whole money because of that man. waaaaa
