Indoor/Outdoor Alarms for Sewage Ejector Systems

HWAB Indoor High Water Alarm

The HWAB mounts indoors and will sound the built-in alarm horn (87 decibles at 10') and illuminate an LED red warning light when a high water level is detected in the basin. When the high water condition is cleared, the alarm will automatically reset. The HWAB includes a NEMA 1 thermoplastic enclosure designed for easy installation and a non-corrosive plastic float swith for use in liquids up to 140° F. To reduce the possibility of shock, the mechanical float switch operates on low voltage, isolated from the 120 volt AC power feed. The battery backup feature ensures the alarm system will work should the primary power fail and is powered by a 9 volt DC battery not included. Be sure and follow all of the manufacturer's directions and instructions and performing the proper maintenance and inspections required to ensure that you are fully protected from flooding. Especially important with man-made safety devices as they will eventually fail.

Frequently Asked Questions

Q. "Do I need to install a vent pipe to the tank?"
A. It really depends on how you plumb the piping to the tank and each situation is different. In many cases with any brand of sealed tank the simple answer is yes as you need air to displace the volume of discharge. An AAV may be used in many areas of the country but local codes always prevail and so best to check with your local code authorities before purchasing the enclosed tank system/s such as these shown on this page.
