After a recent theft I realized my alarm isn't even audible from 30 feet while inside a building. I even recently upgraded to the larger six tone Revenger siren from DEI, but I want more. I want to add one more siren to the exterior and one to the cabin to irritate the hell out of anyone thats inside. My question is is my brain able to support three sirens? Or do I need to use relays or something and power the other two directly off the battery? Let me know how I can do this. I have the Viper 350HV by the way. Thanks.

 

The manual doesn't list specs on how much current the siren output can drive, so you either need to ask Directed, or be safe and use a relay. I'll bet that it cannot drive three sirens... after all, why would they design it to support 300% of stock configuration?

 

I recently talked to another guy that had helped me previously, and he stated that the sirens have nearly no draw at all, so I should be fine with the 12V signal from the brain. I ordered a Pain Generator for the interior and I think I will wire in another Revenger, except jack up the car and put it underneath so they cannot get to it.
