A test of my System Sensor P2RH-LF low frequency sounder strobe. This alarm is very loud, I mean very loud. It was louder than I expected it to be. The strobe on this unit is very bright too (185 CD) These low frequency sounder strobes are really expensive on ebay. I've seen them for around $55 or higher. But I was very fortunate to get this one for free.
