Ahhh sorry, didn't make that clear... I meant hook up a speaker normally (pins 1 & 16) is when the voltage went up on pin 4. Can't say I've tried hooking it up to pin 4, would make for a nice buzzzzz lol. Would I use the ground (pin 7) on the relay? I'm trying to figure out what trips the relay once ...

It does point to pin 4. I get 9v from it, but when I hook up a speaker it jumps up to 13v, so I'm a little baffled as to how it activates (like a relay) with constant voltage. Time to read and learn more about CPS

Can the external alarm can be triggered with the Quik-Call II system using a set of tones to activate a speaker and an LED light?

Any help would be appreciated...


Thanks
