Hi all,
Looking for a little help with our Entrotec ED4 system, would be grateful for any advice, please and thank you! For ease of reading I'll bullet point what the issues are:
I fully appreciate that everyone's time is very valuable and any help would be greatly appreciated. If there's any way to repay for your solution to our problem, would be happy to look into that.
Getting an electrician in is not an option as this is not considered essential work during the lock- down. It's also a massive disturbance to us as we can't open for deliveries which is pretty much the only way to supply the house these days.
Many many thanks for any advice.
Looking for a little help with our Entrotec ED4 system, would be grateful for any advice, please and thank you! For ease of reading I'll bullet point what the issues are:
- The old handset (not sure how many years, but very old) was falling apart and the speaker wire disconnected from the back of the speaker.
- Took it apart carefully and re-soldered the speaker wires - when putting the old handset back and re-connecting the wires in the same order, it would not power up - we tested and could still hear each other through the intercom, but it would not ring or buzz the door open.
- Ordered brand new Entrotec ED4 unit - arrived yesterday. Wired everything up as shown in the pic attached, just as it was in the old unit (New handset.jpeg). No joy. Not ringing when called. If I know my wife is calling and I lift the handset we can hear each other fine. Cannot open door with button. Privacy button LED not lighting up.
- Visited next door neighbour who has the same system. Took a picture of the inside - attached (Neighbour.jpeg). Wiring is the same as mine. Made sure the PL5 and LK 1,2,3 pins were tested in all possible configurations - still the same issue.
- For reference, attaching a picture of our old Entrotec and the new one side by side. New is right, old is left.
- Checked carefully the wires that connect to it to make sure no breaks are felt along the wires, re-snipped and exposed the wires again, reconnected everything, still no joy.
- It feels there's a power issue. The microphone and speaker work fine. There is no ring sound when someone is calling, we cannot buzz the door open or engage privacy mode. I read in an earlier post that the coding of the wires is: DS – Door Status
DR – Door Release
VT – DC in 12V
BZ – Buzz input
S2 - Mic
S1 - Speaker
0V – Ground - I have a multi-meter - picture attached below (Multimeter.jpeg), but don't have the skills to know how to check for power delivery, would appreciate some guidance on how to do it.
