Liberty Pumps ALM Series Pump Alarm ALM-3W

Liberty ALM-3W: Commercial-Grade Outdoor Pump Alarm

Add a critical layer of safety to your outdoor pump system with the Liberty Pumps ALM Series Pump Alarm ALM-3W. This is a commercial-duty, NEMA 4X-rated high liquid level alarm designed to withstand direct-wire installation in outdoor or indoor applications. It provides a loud, impossible-to-miss warning for high water conditions in sump basins, sewage tanks, holding tanks, and other non-potable water applications.

The ALM-3W operates on a 115V circuit (separate from the pump) and activates its 88-decibel horn and a bright, 360-degree red alarm beacon when the included float switch is triggered. The unit features a test/on/silence switch and auxiliary contacts for connecting to remote devices. Built for reliability, this alarm ensures you're alerted to a potential pump failure before it becomes a costly problem.
