Level alarm with audio, visual and app alerts

The Liberty Pumps ALM-2-EYE monitors liquid levels and signals high-water conditions through a built-in horn, a flashing beacon and a wireless notification to a paired device. It operates on a 115 VAC supply drawing 0.05 amps and 6 watts, and includes a 9 V backup battery so the alarm remains active during a mains outage. The unit is housed in a NEMA 1 enclosure rated for indoor use.

86 dB horn and 9 ft power cord set placement limits

The audible alarm reaches 86 decibels at the enclosure, a level intended to be heard inside a mechanical room or basement but not through multiple walls. A 9-foot mains cord restricts the mounting location to within that radius of a suitable socket unless an extension is used. The wide-angle float switch ships with a 20-foot tether, allowing the sensor to be positioned in a sump or tank while the controller stays at a convenient height.

Indoor-rated NEMA 1 case with auxiliary contacts

The NEMA 1 rating means the enclosure protects against incidental contact and falling dirt but is not sealed against water spray or dust, so it must be mounted in a dry, sheltered area. Auxiliary dry contacts are provided for connection to a building management system, a dialler or a secondary warning device. Automatic reset clears the alarm once the float drops, returning the system to monitoring without manual intervention.

Questions about this item

Should I choose the 20 ft float cord version or a different length?

The alarm comes with a 20 ft float cord and a 9 ft power cord, so the float reach is fixed at 20 ft.

What does the 86 dB rating mean when the alarm is mounted in a basement?

At 86 decibels the siren is loud enough to be heard through a closed door and over typical mechanical-room background noise.

Does the 115 VAC supply limit where I can install the unit?

The unit requires a standard 115 VAC outlet and draws only 0.05 amps, so it can share a regular household circuit.
