Latching feature identifies intermittent failures (swingers) and confirms operation of switches at remote locations. In latching mode, the Loop Verifier will catch the alarm condition and continue until the tester is reset.
As a tone generator, this Loop Verifier provides a traditional variable tone that can be applied using the 24" red & black test leads or 6-position modular plug, included. The magnetic, back plate allows convenient mounting directly to control panel cabinets & doors.
