OnLine Power

6.At this point in time, the Fire Alarm Back-up UPS1481 should be providing AC line power. The Fire Alarm Back-up UPS1481 is not operating in the normal mode, turn off the input circuit breaker. Contact OnLine Power at (800) 797-7782 for technical assistance.

7.Recheck that the output voltage is 120/240 VAC.

If the output voltage is approximately same as nameplate, turn on the loads which will be powered from

the Fire Alarm Back-up UPS1481 .

8.The next steps verify battery operation and the inverter test switch.

To place the Fire Alarm Back-up UPS1481 in battery operation (to simulate loss of input power), press and hold yellow Inverter Test Switch. With switch in the hold position, the Fire Alarm Back-up UPS1481 should be running on its internal batteries.

Verify that the LCD panel displays such.

Verify that the “Battery Charger” is OFF in LCD panel.

Note: Be sure to release the switch, after the test, so it will not deplete the batteries.

9.The Fire Alarm Back-up UPS1481 is now fully functional - providing clean, sine wave power to the load with battery back—up in case of an input power failure. This concludes the start-up procedures.

3-2 Operation

3-2-1 Turning On the Fire Alarm Back-up UPS1481 :

1.Apply input power.

2.With input power available, turn on the main input circuit breaker, CB2 (if provided).

3.Close battery breaker (CB1), only after the LCD display is lit & displays screens per Appendix D.

4.Wait till you hear the input contactor closing and fan running.

5.Verify that all parameters on LCD display panel are proper. See Appendix D for display details.
