1.4 Test / Alarm Disable switch
A dual function Test / Alarm Disable switch (400VA and 600VA models) allows you to
check for proper operation by initiating a transfer to on-battery operation. This test
ensures that the UPS is not overloaded and will support the system load during an actual
power disturbance. By using the Test function throughout the life of the UPS, you can
estimate when the UPS's battery should be replaced. During a utility failure, the Alarm
Disable portion of the switch can be pressed to silence the audible alarm.
1.5 Surge suppression and EMI/RFI filtering
The UPS provides high performance surge suppression and EMI/RFI (electromagnetic
and radio frequency interference) filtering. The UPS suppresses surges defined by the IEC
801-5 standard to levels well below that which is compatible with your computer.
1.6 Remote interface
The 600VA model is equipped with a remote computer interface port that is capable of
signalling utility failure and low battery conditions. It also allows for unattended
shutdown of computer operations. When teamed with PowerChute UPS monitoring
software, you may select operation of power event logging, power event notification,
automatic restart upon power restoration, and battery conservation features.
