Omega Psyren

I am looking at adding a few of these to my alpine alarm because i like the quiet features when you arm and disarm the alarm but when my alarm goes off the siren it pretty pethitic. I noticed that there were 2 different styles one big and one small i would like to know which one is the loudest, or are they the same. I will be keeping the alpine siren on the siren output and adding the psyrens to the alarming output like i did the mini pezos.

Thanks for your help.

actually, no.  its not dual tone at all.  its got all the tones of a 6-tone siren, but they overlap.  one tone plays, then the next starts and plays with the first, then the third, etc.  thats what makes it "psycho".  they are VERY nice...

maybe my personal psyren got wet or something, but I've noticed that in brutal cold (we've got -35c here consistently for the last while) the sirens output is substantially diminished.  as the truck warms the siren (underhood heat), its output comes back.

we've had a break in the weather and were lucky enough to get only to the -18c or so area, and the output was fine...just seems the wicked cold hurts its output...anybody else notice this?

last nite we had some pretty severe temps, standing air temperature of -36c!  this morning disarmed the truck and the siren had just about NO output...strange.  in driving to work, underhood heat warmed it and arming/disarming at work later on was normal!!
