Frequently Asked Questions

Q. "What is NEMA?"
A. NEMA stands for National Electrical Manufacturers Association which sets standards and provides a forum for standardization of electrical equipment.

Q. "We noticed most of these alarms use a float switch and are used for water depths of 6 inches or more. Do you offer anything that will detect leaking water from a water heater or washing machine and provide an alarm?"
A. Yes we do! We offer just an alarm for leaking water heaters or washing machines or any appliance for that matter. It is a low voltage alarm. We offer other alarms that will also automatically shut-off the water to the water heater or to the washing machine. And we also offer an alarm that will turn off the electricity to the washing machine (or any other 115 volt appliance) when a water leak is detected.

Q. "Is there anything else I should know about these alarms?"
A. Make sure to follow all of the manufacturer's instructions and directions by performing the proper maintenance and inspections to ensure that you are fully protected; this is ever-so-important with (man-made) safety devices as they will eventually fail. Proper maintenance and inspections can extend the lifespan of your alarm and allow it to funtion properly.
