Gdx Intercoms And Intercoms In General

[Blue Duck]

I occasionally have to add new or move intercom handsets about against my will, I just have to do it as no one else will. So I'm looking for a little enlightenment as to a problem I've had a few times...

When moving one I note the connections disconnect one at a time then tape up the ends then It comes to reconnecting I do the reverse and It won't work!

Do some intercoms have a connection sequence?

I checked the manual for the GDX I was working on today and it mentioned nothing!

I had this today in a house full of cats with sticky carpets and I wasn't able to complete the job and I don't really want to go back But I will reluctantly in a paper suit and gas mask.

Hi,

Did you disconnect the feed to the PSU before moving the handset?

 

[Blue Duck]

Nope this is not possible in most cases as its for the council as they won't do it.

 

[Lurch]

You've blown it up then.

 

[Blue Duck]

Nah it works fine just not where I wanted it to  

I know to tape up the cables to prevent shorts

 

[Lurch]

So it still works in the old position then?

 

[Blue Duck]

Yes...

New position it was a dud but I think this was mainly due to being surrounded by cat crap & wanting out!

I reconnected I the old position (near the front door) It still didn't work the I disconnected and re-connected in a different order and bingo it worked.

This is the beastie ^^^

One of the basic ones then. Unlikely to be a connection order, I'd connect +12V last out of habit, the other wires/terminals are nothing special. Most likely a wiring error.

In the main panel to door unit connection, and RS485/422 or somesuch. Not in the handset connections though.

Thanks for the replies I thought I was going mad but it's probably just the places I have to work in at times.

You haven't put a staple through the cable. ? Of course I have never done that.

 

[Blue Duck]

Nope I've never done that either especially when I'm in a rush!

:innocent

Just like I've never swapped out three new PSU's on a 48 volt DC system before realising there was a second power switch hidden at the back............

 

[Blue Duck]

Ive never taken out 3 pairs with a staple! No Idea how someone would manage that? :innocent

 

[NozSpark]

I'm also :innocent of that
