Can someone help me connect my air horns to my viper alarm.

I have it set up but the horn doesn't "flash" It is just a solid blast. I hooked up a flasher but I don't understand what is wrong. Please look at the picture and tell me what I did wrong and how I can fix it. Or just tell me how to do it or provide a link to a how to.

Thanks

If you can't see the picture it is basically my air horn is hooked up with a relay and I split the power from the siren and put a flasher with 2 diods on it and put it into the turn on wire of the horn.

Hi Dman950, use the diagram shown below except instead of connecting to the positive lead of the lights, connect to the positive lead of the compressor for your air horns.

Hey DMAN950

On the inside of the brain of your alarm there should be a switch that you switch to either constant or pulse. Yours is probably on canstant. Check that

Hi hot_shot_guy, if he's using a pulsed output, the flasher will likely not work properly, so he would want a constant output on the siren lead if he wants the siren to sound continuously and the air horns to pulse on and off. If he's not using the siren and only wants the air horns to sound, then setting it to a pulsed output will work fine if he doesn't use the flasher, but from what he described above, the placement of the flasher on the siren lead and the use of diodes is the problem. The diodes aren't needed and the flasher should be on the positive lead to the air horns on the output of the relay as shown in the diagram above.
