KOW-4.3 Contact Guard
The KOW-4 can check the switched status of 4 independent contacts as well as detect broken wiring and short-circuits.
The different KOW-4 configurations vary in regard to how their alarm outputs S1 to S4 are grouped and are realised by means of different jumper settings (J1, J2, and J3).
