Liberty Pumps Model ALM-2R Wireless Alarm System with Indoor Alarm Box

The ALM-2R is a remote wireless alarm for existing effluent and sewage applications. This new technology allows installation of an alarm in a pre-existing outdoor system without digging or trenching lines to the tank. A transmitter sends a signal to the alarm warning of a high-level condition. The ALM-2R saves labor and damage to expensive landscaping.

Easy to install wireless liquid level alarm system with auto reset and battery back-up features. An electrician is not required since no hard-wiring is needed. When the high water alarm float switch is activated, the transmitter sends a signal, sounding the indoor alarm. No cable to bury, no damage to expensive landscape and no heavy equipment to haul.

The ALM-2R alarm system features a battery operated wireless transmitter that is placed in a tank (up to 150 feet away from the indoor alarm). When the high water alarm float switch activates, the transmitter sends a signal and sounds the indoor alarm warning of a potentially threatening liquid level condition. The horn can be silenced, but the alarm light remains on until the condition is remedied. Once the condition is cleared, the alarm will automatically reset.

The ALM-2R alarm system monitors liquid levels in lift pump chambers, sump pump basins, holding tanks, sewage, agricultural, and effluent filters, and other water applications.
