HELP - GDX Intercom Handset not working :-(

[Dickie87]

Good afternoon,
I have recently moved in to a property which has a communal Intercom system installed but the handset in my flat was ripped off by previous tenant (for some unknown reason ). I have bought a new handset which seems to be a upgrade of the last one (possibly discontinued) & "copied" the wiring from old one as no instructions were sent & now just get "Tel Disconnected" on the display of the external unit.
Privacy button sounds & illuminates when pushed.
Entry doesn't open the door but can hear a fast "engaged"/disconnected line tone through the handset speaker.

Housing Association won't help as I'm in a Private Let property in their complex. Landlord unsure of where to start so here I am seeking any & all advice.

Old Unit - GDX5
New Unit - GDX 23150

Pictures below of old unit wired in to ports 1-4 & same with new unit.

Thanks in advance

Looks like it may be the wrong handset.

Your new GDX-23150 handset is intended for GDX GDX1/GDX3 2 system.

You probably need a 23121 handset for a GDX5 system.

I'm not sure, but the system might also need your flat to be 'turned on' at the control unit.

Your landlord has to raise a maintenance request with the housing association who are the freeholder or factor / managing agents of your building.

Much appreciated, I did see your post earlier but been busy with work & new baby but did automatically order the one you recommended.
All is now working as it should be just by copying the input from old unit, thank you very muchly

Better to have a new baby other than an old one.

I just love it when someone else is just starting sleepless nights, my youngest is 43 next year and I can still hear her crying and screeming as a baby. She nearly didn't make it to two let alone 43.

Still, you still love them don't you?

I'm glad it's sorted out. They're quite expensive systems if you end up buying the wrong bit.

Hello

I have a query concerning the wiring to your new handset intercom.

Did you re-attach the wires into their respective ports using a particular sequence or not ? ie white & blue first, then blue & white second etc etc ?

I hope to install a replacement GDX-23121 in the days ahead and am wondering if the rewiring needed to be done via a sequence.

Thanks...
