Zusammenfassung:A self-protecting valve assembly for use in conjunction with a sump pump test and monitoring system having a test control module which generates a valve control signal for opening the valve to initiate a test cycle. The valve assembly includes an electrically-actuated valve which is responsive only to a valve-actuating signal and not to the valve control signal. A conversion circuit in the valve assembly converts the valve control signal to a valve actuating signal to actuate the valve. This protects the valve from receiving a false actuating signal in the event of a failure in the test control module.
