Battery Backup

Supplies power long enough for equipment to properly shut down when utility power fails. Helps prevent loss of data and minimizes the component stress caused by a hard shutdown.


A power failure in which line voltage drops to zero.


The AVR function of a UPS which increases voltage when the utility power approaches the low voltage threshold.


A drop in voltage for an extended period of time.


The AVR function of a UPS which reduces voltage when the utility power approaches the high voltage threshold.


Full automatic voltage regulation in a UPS stabilizes low voltage (boost) and high voltage (buck) to maintain nominal 120V power without resorting to battery power when minor power fluctuations occur.


The current battery charge, expressed as a percentage of a full charge.

Cisco Compatible

Means that a product meets the standards set by Cisco, a global leader in IT.

Coaxial Cables

Cables that are made of an inner conductor surrounded by an insulator and a shield. Generally used for TV antennas, satellite dishes, cable modems, and certain computer networking applications.

Communication Interface

Alarm Telemetry to an optical network terminal or a connected device. Contact closure alarm with NC normal state.
