Hello -

I've just mounted one of the old style (round buttons) Trimlines in my bathroom. Can anyone tell me which terminals are used to supply voltage to the handset lamp - and what voltage it needs? It looks like the same style 10v lamp from a 1A2, but just want to make sure.

Thanks!
Matt

Looking at my old schematics collection, looks like the transformer is "6-8V 60~", if modular connects to the Black and Yellow of the line cord.

Internally, the yellow connects to Terminal "3", along with the white conductor to the handset, while the black connects to Terminal "1", along with the blue wire from the hookswitch (which is normally closed, the other side is orange, connecting to terminal "4" with the black conductor to the handset)

I'm sure TTT has it right. I couldn't find my station book, but I remember they were 6 volt lamps.

WE 2012A transformer, 6-8 volts.

The lamps are 52-types; physically, they are slightly shorter than a 51A, which uses 10 Vac.

You won't blow anything up by experimenting to see which leads are the right ones.

Thanks all -

TTT had it right, terms 1 & 3. I hooked it to the 10v of my KSU. Lamp burns a bit brighter than perhaps it should, but it will only be off hook maybe 5 times a year (That's a rough guess based on the number of times I've been in the bathroom when the phone rang) for about 1 minute per call, as I really don't enjoy bathroom phone conversations. I just put the phone in there because:

1) It's not normally something you see in someone's house (kinda like ... maybe a 1A2 system)
2) I think it looks cool
3) I had to do it to bring the upper level of my house closer to my personal telephone code; para. 1, section 2; subsection 2.1.0.4:

There shall be no distance greater than seven feet in which a telephone is not available.

But Arthur - bad news - you got this one wrong.... sorry; I hooked it all up, took it off hook, and my neighbors house exploded.

So, just 4 more 1A2's to put in, and 2 more trimlines.

I'd hate to think what would happen if it was the old days and ma bell would come knocking (supposedly, anyway) if your ringer equivelance value (I think that's what they called it) went over a certain threshold. I saw a Green Acres the other day, and apparently the thing that people used to have to do was have one or two phones, and if they wanted to talk in a different room they had to unplug the phone and plug it back in wherever they wanted to talk from.

Thanks again all -

One other thing, and I have to share this as it's never happened to me before.

There was a cold water pipe already running up the stud space I wanted to mount the phone over. One hole drilled in the sheet rock, a fish tape fed from below, grabbed it through the hole with a coat hanger, taped the wire to the fish... had the whole thing mounted and wired in 10 minutes.

Then with your guys help got the lamp working.

Never had this kind of luck with anything in my life, as far as mounting electrical/electronic devices in my house. I've talked about it in other threads, but last time I tried something like this I drilled straight through a 220v cable.

That was interesting; and there was absolutely no doubt what I'd done, what with a blue flame shooting out of the hole for a brief second, and my extended drill bit melted by 1/4".

I think you are going to find that you are going to need "A" lead control on those babys with a 1A2.

YES!!!!

I want, if possible, to only have 2 of them. All my single line phones are home run, or at least... they will be. I'm hoping I can use one for each incoming CO line; keeping in mind I have absolutely no idea how these devices are connected in.

May you by chance know of a source?

Thx
Matt

Don't know about your area, but around here, it is illegal to install a phone in any bathroom....shock hazard.

"There shall be no distance greater than seven feet in which a telephone is not available."

I find that statement to be totally ridiculous.

For some reason, I think I can resist the urge to answer the phone when in the bathroom. If it's important, they can leave a message. Unlike some of my customer's I have never missed a million-dollar phone call.
