Tank Alert –
SJE Rhombus


When it comes to waterproofing, reliability is always a number 1 concern for every property owner. As a contractor, you offer your client’s protection and peace of mind. With the Tank Alert AB alarm system, you can now provide them with a reliable early warning system. Tank Alert is a battery-powered alarm system that monitors water conditions in lift pump chambers, sump pump basins, holding tanks, sewage, agricultural, and other non-potable water applications.

  • Tank Alert – SJE Rhombus

Product Overview

The Tank Alert AB alarm system is a simple and easy-to-install liquid level alarm system with auto-reset and battery backup features for indoor use. The Tank Alert AB alarm system can serve as a high or low-level alarm depending on the float switch model. The alarm horn sounds when a potentially threatening liquid level condition occurs. The warning alarm can be silenced (unlike most sump pump alarms), but the alarm light remains on until the condition is remedied. Once the condition is cleared, the alarm will automatically reset. A green “Power On” light indicates 120 VAC primary power to the alarm. A low battery chirp feature indicates when the battery should be replaced.
