SECTION 1 — OPERATION

1-1 INTRODUCTION

The Fire Alarm Back-up UPS1481 provides an exceptional level of load protection and monitoring capabilities. The critical load is provided with conditioned, regulated, computer grade power at all times. There is complete electrical isolation between the input and output voltage of the UPS.

When input power to the UPS is lost, such as during a power outage, the UPS automatically draws power from its internal battery supply. The critical load receives only clean sine wave power. There are no disturbances or power interruptions on the output when the UPS transfers to battery operation. Transfers to and from battery operation are “No Break” transfers. The internal maintenance-free batteries provide ten (10) to fifteen (15) minutes (depending upon model) of backup power. The 10 and 15 kVA models have separate battery cabinets.

Upon restoration of input power, the UPS automatically resumes normal operation. Also the UPS immediately begins to recharge the batteries.

The Fire Alarm Back-up UPS1481 provides comprehensive monitoring capabilities. In addition to the LED indicators and audible alarm, the Fire Alarm Back-up UPS1481 contains a 160 alpha-numeric display and touch pad. UPS status, event history, and operating parameters (such as input, output voltage) are readily available to the operator via the touch pad and display. The UPS 1481 contains, as standard features, an AS/400 interface, RS-232 interface, and printer interface.

The Fire Alarm Back-up UPS1481 is an on—line single phase UPS available in output ratings of 3, 5, 7.5, 10, 12.5 and 15kVA. The UPS 1481 is U.L. listed under UL1481. The Fire Alarm Back- up UPS1481 is available with input voltages of 120 and 240/VAC and output voltages of 120/240/VAC. This information is provided on the name plate located on the rear panel of the UPS. See Appendix A for a complete listing of the UPS 1481 specifications.

1-2 BENEFITS

The Fire Alarm Back-up UPS1481 is designed to fit the needs of virtually all power conditioning and UPS applications. It has been specifically designed to power all forms of modern data processing, communication, and process control equipment. The Fire Alarm Back-up UPS1481 does not require any decorating as other UPS products may when powering 100% electronic loads including switch—mode power supplies.

The Fire Alarm Back-up UPS1481 protects sensitive electrical equipment, such as computer systems, telecommunication networks, LANs and multi—user systems, and instrumentation
