With that, I want to say no as to having BOTH. Ya, the MAN mode on the DEK is confusing. You think it would be you hold it and get a "start up wail" and when you let go, either the wail stops, or falls back down. The MAN mode seems like, like you said, a standby mode for the siren while the SIREN button is enabled, as well as allowing the HORN RING INPUT to be operated.
The problem is that you really can't have both. There is only ONE horn ring input. When it is grounded, it sets off whatever is set for the manual mode in the RSS, which the possible choices are AIR HORN, WAIL, and YELP. As mine is set up as air horn, when grounded, it sounds it and when not grounded there is no sound.
I personally haven't tried it with WAIL or YELP, as I don't (and have no need) to use them so they are not programmed. I would assume that if set to yelp, you would get a YELP tone when the horn ring is grounded and when ungrounded it is shut off.
And I know what you are saying about the WAIL and MAN buttons. If i remember, you put wail on, and let it sound, and when you push the MAN button, the wail tone falls. I actually don't know, but if you have horn ring set to WAIL, I am wondering which one of the following things it would do:
1: while the horn ring is grounded, the WAIL goes up and down just like the normal WAIL button and when you let go of the horn ring, the WAIL STOPS and does not FALL.
2: while grounded, the wail goes up and down, and when you let go, the tone actually falls.
And for both of those, I wonder if while the horn ring is press, it just continues to wail up and down, or does it just wail up and max out at a certain point, and when you release it, it either falls or stops completely.
btw, if you don't know, when you have WAIL selected, you can use the SIREN button to give short bursts of the WAIL. When wail is selected, and u press the siren button, the wail will start to wind up from its lowest point, and when you push siren off, it will stop and not fall. Activate siren again and it will start to wind up again from its lowest point again like it did previously.
Let us know how it goes or post if you need more info!
