RESOLVED: System Sensor HW (Not Functioning)

About 3 days ago I purchased a System Sensor HW from a local fire alarm company (not revealing the name). I carefully removed it from it’s carton. At the testing point. Using 3 Nine volt batteries made by Duracell. It didn’t function. I paid 59.99 for it.
So is it a defective one or was it damaged during shipping?

I can’t post pictures since I don’t have a camera and i’m using a laptop that has no camera.
Wiring was done properly.

Ok so the wiring was done properly… you wired the three batteries in series (+ to - to + to - to + to -) and connected the - to the - on the horn and the + to the + on the horn and no sound?
If no sound, return it, it’s DOA.

If you want some stuff for your collection why not consider getting one of my Mystery Boxes – you’d get 6 or 7 devices for less than what you paid for that one horn.

Thanks for telling me thats it’s DOA. I have since returned it and got two of them. (Warranty)
