Entrotec ED4+ problem

[mac86]

Hi all,

I have noticed that Entrotec ED4+ intercom handset does not want to ring. Well it's a sounder. I know it's very similar issue to this thread here https://www.diynot.com/diy/threads/entrotec-ed4-handset.463654/ (I thought I should make a new thread as this is about a slightly different model, the + and I am not sure about rules on old threads)

I am not sure that it is the speaker at fault as when someone presses the button on the panel outside, while I can only hear for a nano second the sounder alarm go on the ED4, when I pick up the handset I can talk to the person without problem. I can release the door too so it's not a power issue. And it's not the privacy button as that LED is off, and I can as I said, hear the sounder for about half a second if that before it goes off.

All cables in are tight, and it did work when it was intalled brand new 6 months ago.

Obviously, due to the coronavirus issue we have, this is not deemed to be an urgent repair for the company that installed them, so I need to probably fix this myself.

Other neighbours do not have this issue as I have spoke with them and their ones all work okay so I suspect it is the handset, or something in the handset.

Any advice would be welcomed.

I repair these systems and normally it’s the handset at fault ....but I’ve been to one in the last month and it’s the main pcb controller that is the issue as I wired a handset to the controller and tried it ....normally it puts the call LED on solid but it kept just flickering the LED about 2/3 of calls ...a call to tech support pointed towards a pcb component fault this was a 10 year old system , how old is yours ? What is the date code inside your handset ?

 

[mac86]

The date inside is 10/19 so it's pretty newly made.

Is the full system new or your handset only ?

 

[mac86]

It was a brand new full system. I know it's under warranty but they won't fix it as I said while all this is going on as it's not essensial.

Unfortunately you will have to live with it

Living with it is not an option though as I have already had issues with vital deliveries being missed due to this (medication for one). I know the EX slot is empty, and is for an external sounder/strobe. I wonder if I can utalise this for the time being? And if I can, any suggestions to what would work and help?
