UPS Maintenance > User Input
Three programmable User Inputs exist. Their functions are similar to the Dry Contact relays. Supported functions
include: (a) Shutdown, (b) User Alarm, (c) Self Test, and (d)Inverter Off.
Any user input can be configured to perform a certain action in response to different trigger types and logic
levels. For example, if you want the Alpha FXM to issue an intrusion alarm when the door is opened, you need to
wire the door with a switch that triggers a user input every time the door is opened.
The following procedure describes how User Input 1 can be configured as an intrusion alarm input.
