Federal Signal SS2000 Horn Ring Question

[VII]

I'm reading the manual and it is unclear,


Does the horn ring accept positive horn signals for the horn ring feature?


or only negative signals?


My vehicle outputs a positive signal when the horn is depressed.


Thank you

The SS2000 only accepts negative trigger you will have to use a relay to switch polarity. It will work with a relay

You sure about that? I haven't done a Smart Siren in a while but I thought it could do either.


I know its recommended to use a relay if you are connecting between the horn relay and the horn, because of potential amp draw from the horns.

Twodogs you are correct.


I called FedSig and they told me that polarity doesn't make a difference, as long as the Horn Ring wire is open at rest. All it needs is to sense change.


Thank you for your help.
