Hello everyone. New member although I've read through a few times.

I have an air horn connected with a relay to the factory horn output. I want to add a second siren and was wondering if I can use the same relay I'm using for the horn. I would connect both sirens to the +30 and the alarm siren output to the +86 of the relay. Will this cause any problems? Also, how would I get the horn to be intermitent?

Any help would be great.

Thanks.

Yes. It's a Prestige alarm. Can't remember the model number.

If you want the horn to be intermittent, i'd use a flasher(like a turn signal flasher). It'd go ON OFF ON OFF ON OFF :)
Keep the siren output on 85 or 86(whatever the polarity may be it doesnt matter as long as the other one is opposite it) and I'd put 30 to battery power and 87 to the sirens.
