Hi everyone

I've been asked to replace an old and faulty door intercom system for 3 flats. The existing handsets in each flat plug into the mains (with transformer plug) and the tenants want to keep it this way as all the communal lights are currently supplied (and therefore paid for!) by one flat and they don't want to add to the cost for this flat, as power for the intercom would have to be taken again from this flat.

Does anyone know any systems like this? Door release not required - just buzz and talk

thanks in advance

I know the ESP Enterview 5 is handset powered, but it's only a one station system, and it's video as well though.
Check out their webby or give them a ring to ask the question.

I must admit i have never seen a unit powered from the flat end. And with good reason- imagine flats spread over different phases each with their own version of 12v converging at the door end panel. I dont think the panel would like it!

They run on next to nothing- cant they just be done with it and stick it on 1 of the flats? Why not put the landlords stuff on a private meter instead?

Could always do brain surgery on 3 seperate kits to make them combined?

Always had a good result with Bell system intercoms.

I was just going to suggest similar to peteTLM - so either:

1 - door entry system takes next to nothing - one flat is paying for lights - so another can pay for intercom;

or

2 - depending on how they are wired - could you not use 3 separate systems so you have 3 small call button units by the door 1 for each flat - you said there was no door lock to release - even if there was separate systems the relase an be linked

thanks for the replies everyone!

They don't need video but will call ESP tomorrow to see if they have anything suitable
There is no landlord's meter, hence why poor old Flat 1 is paying for all the communal stuff. It would only be realistically possible to connect the door entry to Flat 1

The fall back is as Delbot suggests, but as I've been specifically asked to replace what's there with something that is powered in the same way, I wanted to do a bit of research before I said NO!

cheers all

Actually just realised that maybe option 1 is the only fall back, as for 3 separate systems, I would still need to get 3 lots of power from the individual flats to the front door - which due to the layout and nature of building will be a bit tricky/expensive

How about something like this:

With the outdoor unit being battery powered each flat can be responsible for maintaining their own intercom.

thanks again - weird -that looks like a possible option!

Realised that the old system was ESP and spoke to them - they don't make that type of system any more and did agree it was a bit unusual!

Cheers all
