View Full Version : Additional Noise

10-18-2006, 11:27 PM
Added an additional DEI Piezo and connected the car horn (with the exisiting DEI 6-tone siren) to my 791XV, but it still wasn't good enough from my car being broken into. ...granted my backup battery failed, I got a new one put in which should be working now.

Are there any insanely loud exterior sirens that I can add, which I ONLY want to go off if my backup battery goes off. This way... in case of false alarms, I don't want 5 sirens blaring and causing the neighbors to be pissed at me. If my main battery gets cut, then I want every siren to go off and to make a TON of noise (hopefully scaring away the theif).

I was thinking something like this:




Any suggestions?

the second one seems more practicle, buuut the first one looks VERY loud. Id go with the second one, and add 2 or 3 mini piezos to the interior. No thief will want to be in that environment

You guys all talk about how loud the mini-piezo's are... i just really don't think they are that loud. Maybe the ones I have at work were a bad shipment... but I wired up three in my car and they really don't hurt my ears per say.

I have four in my car and it hurts my ears outside the car. Ive never actually sat in the car to take a listen though.

Is there a way to make the additional sirens go off only when my backup battery is tripped?
