BR900GI Master and controlled by master question

[Anonymous user]

Dear all
I got a APC BR900GI http://www.apc.com/resource/include/techspec_index.cfm?base_sku=BR900GI&tab=documentation.

As far as I understood, looking at the picture here:

http://www.apc.com/resource/images/salestools/500/Back/DAB4DF04E697E9DA852576A4005844DC_MMAE_7ZGM2V_...

The top plug on the left column is the master (M) while the second of the same column is the controlled by the master (CbM). on the right column the first two are controlled by the master too but are surge only.

Now connecting device 1 in the M plug, and a light on (CbM) in normal conditions when i shutdown device 1 after some seconds the light turned off, and viceversa when device 1 is turned on the lights after a few seconds it turns on.
But simulating a power outage, going both device and light on under battery backup, if I turn off device 1 the light remains on. Is this behavior correct or should it turn off as well?

Thank you for your kind answer.

DK,

The controlled by master outlet should still follow the behavior of the master outlet when it is running on battery.

Repeated the test yesterday, same result.

And a new information: when I turn the switch on (from electric panel) again, the monitors (plugged in "controlled by master" outlet) turn off.

Does anyone has a clue?

Thanks a lot.

Hello.

I have a brand new APC PRO 1000 (BR 1000G), and it seems that my UPS have the same behavior.

The ups outlet setup:

(MASTER) - Desktop computer
(CONTROLLED BY MASTER) - My two monitors
(the 3rd outlet that provides battery backup that is not related with the other two) - CCTV, alarm, telephone, router and modem.

When the power from wall outlet is ok, I turn on my desktop and my monitors go on. When I turn my computer off, the monitors shut down after few seconds. The 3rd outled mantains power, no problem at all.

However, I made a test turning off the power (using the switch located in the electric power switch panel). Doing this, the monitors conected at "controlled by master" unexpectedly turned on, even though my desktop (conected in master) was off. The equipments conected at the 3rd battery backup outlet remained on all the time, as expected.

What can it be? Is there a specific configuration for that?

I am worried because turning the monitors on at a power failture would drain my battery quick, and this upc mantains the alarm and cctv systems runing.

Thanks a lot

No clue at all?

Am I asking for help in the wrong topic?

Thanks
