Re: (ET) AllTrax On - questions and horns -reverse beeper ?

["John B Reinhard" <reinharj frontiernet net>]

For those who are trying to use the 50 mA output from the Alltrax 
controller
as a reverse beeper, I think the Mallory  / Sonalert Piezo horn draws very
little power & makes lots of noise, so might work well for that purpose.

What does AllTrax recommend?

I understand that Rod is trying to use it for something different? - or 
just
wants louder?
