Re: HOW to convert signal level for external-siren

["RockyTSquirrel" <gafa@/nospam/usa.com>]

like frank said  you got a 50/50  chance of getting it right the first
time..
just make sure the banded end of both diodes are in the same direction..

if the siren keeps sounding in the off condition,  then reverse the diodes.

if that stops the sounding,  then trip the alarm and make sure that they do
sound in alarm..
