The High Liquid Waste Level Septic System Alarm comes in two presentations. The first is a local (wired) outside alarm that you will see as the smaller single-light siren box in the photos. It comes with everything you need to setup this alarm, which includes the plugin siren box. It comes complete with 50ft of ground wire and a corded float switch to measure hi liquid waste level in your septic tank or lift station.
The second presentation performs the same tasks as the first with an added wireless function that plugs in remotely indoors (within 300 ft of the local outside alarm). It is the plugged, round, red siren in the photo. It also comes with a larger plugged box as shown in the photo. By the way, there is nothing to program and no batteries…all that is needed is to plug it in!
