Hi,

In a hospital, I've got a UPS in a basement that powers an x-ray machine on the ground floor.  If the UPS were to switch over to battery power, you would never hear the built in UPS alarm.

What I need is something in the ground floor room that can plug into the UPS and sound an alarm when the UPS switches to battery power.
There are no PCs in the ground floor room so I can't run an ethernet/RS232 cable and use a software warning like LanSafe. 

The UPS is an Eaton Powerware 9355 and comes with the standard X-57 relay (which can output an alarm signal).

Help please :)
