Free-run truealert horn/strobe needed

As some of you probably know, my current truealert is a smart sync. However, I need a free run unit. Does anyone know of free-run truealert horn/strobe models? Maybe a list if possible?

I have one for sale, actually.

The model is 4903-9426 and it is 75 candella.
There’s a small switch inside where you can choose whether you want to run it in free-run or SmartSync.

$20 + shipping. Send me a PM if you want it.

I checked out some of your alarms for sale.
Great prices, may just have to buy one or two myself.

I do quite enjoy your YouTube vids as well.
