HHS3200/4200 TA feature

[militarymedic23]

Hello,
Hello,

Looking at purchasing a HHS3200 unit, but had a question on a function I’m not quite understanding from the install instructions. I sent this off to Whelen but wanted to post it here to for more feedback.

On the handheld remote, the option for TA Display seems to activate outputs 7 and 8. Yet in the install diagram it says output 8 isn’t even used.

I can see the possible flash patterns in the software to set, but I’m not quite understanding how 2 outputs could allow or produce the flash patterns listed in the software that usually require 4 or more outputs. On the handheld or other 2 control heads the TA indicator already has 6 or so LEDs to show the pattern.

The traffic advisors I’ve worked with and currently have now have 6 or 8 individual contacts so it can make the various directional patterns from a control head.

I guess I could see the 4200 having the wecan port to allow for other functions but the 3200 doesn't have that.

Boggling the mind at the moment....


Could someone respond back with a more detailed explanation of how this function works?

Thanks


Thank You

Hey, so heres my explanation, I hope it helps. They recommend you using a TA that only requires one input per direction. So one output controls the left TA, and one output controls the right TA. In the installation instructions that you read, those numbers where it says that number 8 isn’t used, is referring to the pin-out, not outputs. Output 8, is pin 9.

Ok, I think I’m following. But to give a bit more for a visual aid, are there specific TA models I can lookup and see the wiring details?

This is a low current lightbar.

Hmm, so if this is the general way lightbars do their TA wiring, would this be kind of a mute point to look into or try and configure with the majority of the standalone TA’s?
I have a TACTLD1 that is controlling my current arrow stick.
don’t see anything in the wiring that would allow 2 different activations, just the aux single input wire.

I don’t have much experience with anything other than Whelen, and 99% of what I deal with is WeCan, so I really couldn’t answer that question.

No worries.
I see a few Whelen TA sticks available which follow the wiring that has been described here. But if what I have works, just controlled by a separate controller. Don’t see the need to go out and buy a whole new arrow stick just so the HHS unit can control it.
