3.4 Zone Inputs
Each Zone Output has a corresponding Zone Input. Each Zone Input provides on/off control for its
associated output. Inputs are programmable for a variety of input types, including:
y
Open Collector Input
y
Isolated Voltage Trip
y
Non-Isolated Positive Trip
y
Non-Isolated Negative Trip
y
Normally Closed Dry Contact - Negative Switching
y
Normally Open Dry Contact - Negative Switching
y
Normally Closed Dry Contact - Positive Switching
y
Normally Open Dry Contact - Positive Switching
See Appendix A for specific information and example wiring diagrams for connecting the Zone
Inputs.
3.5 Zone Outputs
Each Zone Output of the APD8(F) can be used as a dry contact output, or as either a fail-safe or
fail-secure voltage output. Jumpers JP1 through JP8 select the type of output for each zone (see
Section 5.1 for jumper information). See Appendix B for more information on the Zone Outputs.
3.5.1 If the Zone Output is configured as a dry contact output, the following connections apply:
y
NO
Normally Open relay contact
y
C
Relay Common
y
NC
Normally Closed relay contact
3.5.2 If the Zone Output is configured as a voltage output, the following connections apply:
y
NO
Outputs voltage when the zone relay is active
y
C
Always outputs voltage, regardless of relay condition
y
NC
Outputs voltage when the zone relay is incative
y
COM
This terminal is the DC common associated with the output
