Setting the DIP switches
1. Power down the NX-507E/NX-508E output expander.
2. Set the DIP switches according to Table 10. NX-507E/NX-508E output expander DIP
switches.
Note: Switches 1-3 set the module address. DIP switch 4 enables the tamper.
• •If DIP switch 4 is ON, the NX-507E/NX-508E generates a tamper alarm when
the TAM line is unconnected to the COM line.
• •If DIP switch 4 is OFF, the NX-507E/NX-508E does not generate a tamper
alarm if the TAM line is unconnected to the COM line.
