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.

1.5SurgesuppressionandEMI/RFIfiltering

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.

1.6Remoteinterface

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.
