ZR8 Relay Card jumpers
JP1 – JP8 configure which relay contacts are
present on the terminal connections for R1 – R8,
respectively.
The normal operating state of the relay (on or off
when the panel is normal) determines whether
the terminal connections are normally-open or
normally-closed.
The figure to the right shows the relay contact
positions when the relay is turned off.
