Review on Highly Efficient LTE 5103J Strobe Industrial Flashing AC110V 120V: Top-Notch Performance by Dan Bobbert

This alarm was easy to install and seems to be working fine. We installed it on our septic tank pump because our pump failed during heavy rains this spring. The problem we have is that in daylight we see a flashing red light AND a shrill alarm sound. I can barely hear the alarm in the house and my husband can't hear it at all because of the high-pitched tone.
