this terminal and common.
COM
Connect to the tamper terminal through a normally closed contact.
This terminal can supply up to 100 mA fused separate from the power in the control panel.
AUX
Any power drain from this terminal should be included in total current draw from the
NetworX control panel or NX-320E Power Supply as applicable
.
This allows an isolation
of the power between the main control and remote devices. If a short is created past the
AUX

display on the keypad as an expander power trouble.
