Note 1:
The circuit in this example is equivalent to a Category 3 circuit.
Note 2:
If two or more Sensors are connected to one Controller, all of the guard doors must open and close independently. If two or more doors open and close at
the same time, it is possible that a fault may not be detected.
Note 3:
Up to six Sensors can be connected to a single Controller.
