{p}I cant beleive I am having this much trouble convincing everyone to forget about the Siren. My Siren circuit is completely seperate. My Siren circuit is a constant (+3V) output. IT IS {SPAN style="FONT-SIZE: 10pt; LINE-HEIGHT: 115%; FONT-FAMILY: 'Calibri','sans-serif'; mso-ascii-theme-font: minor-latin; mso-fareast-font-family: Calibri; mso-fareast-theme-font: minor-latin; mso-hansi-theme-font: minor-latin; mso-bidi-font-family: 'Arial'; mso-bidi-theme-font: minor-bidi; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA"}IRRELEVANT to my Horn Circuit. My horn circuit is a pulsing (-500mA) output. PLEASE FORGET ABOUT THE SIREN.{/SPAN}{/P}{p}{SPAN style="FONT-SIZE: 10pt; LINE-HEIGHT: 115%; FONT-FAMILY: 'Calibri','sans-serif'; mso-ascii-theme-font: minor-latin; mso-fareast-font-family: Calibri; mso-fareast-theme-font: minor-latin; mso-hansi-theme-font: minor-latin; mso-bidi-font-family: 'Arial'; mso-bidi-theme-font: minor-bidi; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA"}My horn output signal is On for a second, then OFF for a second, then ON again etc. This gives the Honk-Pause-Honk-Pause Effect. I dont want a pause. When the signal is off and the horn is in a pause state, I want it to honk another horn. There will now be an alternating horn effect between the factory horn and the electric air horn. I am looking for maybe a DTDP relay wiring diagram that when the factory horn is NOT honking, the Air Horn will be. Man I know this sounds confusing, and I may not be able to do what I am trying to do but I fihfured I would try anyway.{/SPAN}{/P}{p}{SPAN style="FONT-SIZE: 10pt; LINE-HEIGHT: 115%; FONT-FAMILY: 'Calibri','sans-serif'; mso-ascii-theme-font: minor-latin; mso-fareast-font-family: Calibri; mso-fareast-theme-font: minor-latin; mso-hansi-theme-font: minor-latin; mso-bidi-font-family: 'Arial'; mso-bidi-theme-font: minor-bidi; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA"}Thanks for your patience,{/SPAN}{/P}{p}{SPAN style="FONT-SIZE: 10pt; LINE-HEIGHT: 115%; FONT-FAMILY: 'Calibri','sans-serif'; mso-ascii-theme-font: minor-latin; mso-fareast-font-family: Calibri; mso-fareast-theme-font: minor-latin; mso-hansi-theme-font: minor-latin; mso-bidi-font-family: 'Arial'; mso-bidi-theme-font: minor-bidi; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA"}LC {/SPAN} {/P}

If you insist on not using the siren wire. I can not help you. Without the siren wire powering the second relay, your air horn would go off all of the time. The second relay will alternate horn, airhorn, horn, airhorn, just as you want it to do. The siren will constantly be going off. You need to not worry about why the siren wire is needed and build the relays to prove to yourself that we are not giving you good information. Once Again In Goes The Towel. Print the picture, bring it to someone who has a clue about a relay and see what they tell you.

Dispensing free help has never been so hard.

In your earlier post you wrote

It is not confusing to me.

I think I know how to accomplish this. If I tie the constant +3A (12V) output wire from the siren to power the coil of the first relay to then supply 12 V to a second relay, use my my negative Horn output to activate the second relay, hook the two horns on the seperate tabs of the second relay, when the circuit from the negative horn output opens and closes the second relay will be alternating between the two horns. The system will only be active when the alarm is triggered causing power to the siren and activating my switching horn relay.
