The LB50 indoor/outdoor alarm from Septic Services is designed for high-water detection for use in industrial and commercial systems. It has a warning light and audible alarm along with an easily accessible three-position switch to change the alarm among normal operation mode, alarm silence mode and alarm testing mode. It is fused to protect the internal electrical circuitry against power surges and spikes. The impact-resistant polycarbonate housing is designed to further protect the circuitry from corrosion. It comes with a 9-foot 6-inch float, making it compatible with commercial and residential sewage systems, dosing chambers, lift stations, cisterns and other water and sewage systems that require high-water detection to prevent equipment damage or failure. It is easy to install by connecting the level control switch to terminal blocks and plugging the 7-foot power cord into a 115-volt outlet. 800/536-5564; www.septicserv.com/store.
