TraceTek products monitor with in a fully supervised 4-wire circuit configuration.
Current is flowing on all 4 conductors all of the time even when there is no
leak. A TraceTek control module cannot be "disconnected" from any sensor
lead and not recognize the event and then report it. This is not always true
with 2-wire and 3-wire monitoring circuits. TraceTek leak detection systems
are UL Listed under Process Management Equipment and Tested to Standard 864
(Fire Protective Signaling Systems). Fire Protective Signaling Systems require
the use of fully supervised circuits.
