Hi there, I'm a bit stuck. I'm looking for an external bell to run off an optipoint 500 digital phone. There is an "acoustic adapter" that plugs into the back, and the bumph in the manual says the following:
2. Second contact (PIN 4 and 5)
This provides the ring input status.
This contact can provide an external signaling mechanism when the telephone rings. This
is important when connecting a secondary bell or similar device. Once again, observe the
electrical connection values for this connector as well (24 V - 60 V, 5 W; do not connect an
inductive load without surge protection). However, you can also connect a relay instead of
the lamp, with this relay then controlling the 220 V secondary bell
Contact Load
Both contacts can carry the following load:
5 W with 24 V a.c. or 60 V d.c.
My question is, am I looking for a ready made unit, or am I looking for a relay (I have a vague idea of what that is from my school days 30 odd years ago...) and a bell, or a kit or what.......
Many thanks, Al.
