CS1000 Alarm System

Easy-to-Install Indoor Alarm System


cs 1000 tank alarm

The CS1000 Alarm System monitors liquid levels in lift pump chambers, sump pump basins, holding tanks, sewage, agricultural, and other water applications.

The CS1000 alarm system can serve as a high or low level alarm depending on the float switch model used.

The alarm horn sounds when a potentially threatening liquid level condition occurs. The horn can be silenced, but the red warning light remains on until the condition is remedied. A green “power on” light indicates power to the alarm panel.
