Door Entry System Wiring - Replacing a handset

Postby DIY_Junkie » Mon Oct 13, 2008 11:34 am

Hi there,
I've just bought a replacement handset (Bell 801) for my door entry system. The existing phone that I'm replacing has 5 wires going to different parts of the handset but their destinations are marked A B C etc. The new handset has connections marked Z T 0 R 1.

The incoming wiring has very thin red, blue, brown, grey (or at least it now looks grey after 20 or so years) and orange wires. The orange one seems to go to a single destination and then carries on to two other terminals. The others all go to single terminals.

Can anyone help me to identify which wires go where on the new handset?

Please see the images (all can be resized larger) at ... iagram.gif ... _small.jpg ... _small.jpg

Any help much appreciated! Thanks!

Because the wrong people could use this information even if we had it we would tell you on here.

Without going into detail then, for anyone else who comes across this problem the answer is that there are various conversion charts on the web for mapping existing connections to new connections. You just need to know the make of your existing handset and cross reference those connections with those of the new handset.
