System Sensor P2WL Horn Strobe

Works good and sounds good. System sensor did a amazing job on this unit and looks good flush mounted

I am deaf without hearing aids so I rely on the strobe feature. This works well but not on the fire side of a Vista 20p. Fire signal is a pulsing 12v and this unit won't regulate it. I now must look into rectifying the problem with some kind of interfacing. Wish the description stated this since so many use the Vista alarm panels.

Nowhere, does it say you have to buy an adapter to wire it directly to your home. Blew a circuit blew the sensor The description does not fit the product
