Speaker/Strobe ID?

I got a couple of these speaker/strobes in the mail today, and have never seen them before. They have a label on them, but don’t have a brand or model number. Does anybody know what they are?

Looks like it’s an Integrity PowerSaver signal, hence the different-looking strobe. An LKC-1 lens kit appears to have been installed, changing the orientation of the strobe’s lettering for a ceiling-mount installation.


Always wondered what the PS stood for, I originally thought it was “Partial Strobe”

Thanks for the info, guys!
