Do you really turn the entire entertainment system off when you

We were having some less than a second power blips that would knock
out the sat receiver. It was such a PITA that I finally put it on a
UPS. Problem solved.



Problem may not be solved. My BIL had his satellite system on a UPS
to take care of the blips then one day when they were away from the
house for a few hours because the power had gone out for an extended
period of time the UPS went dead and the satellite tuner/DVR
permanently freaked out because of the low voltage coming from the
UPS as it was running out of back up power. He created his own brown
out machine. The whole tuner/DVR had to be replaced.

Crappy UPS in that case. A decent UPS would provide signalling to
shut down
the system at the point where power was getting marginal.



Can you name a UPS that will actually do what you said, signal to shut
down the satellite receiver/DVR? I don't know of any satellite DVR's
that actually communicate with a UPS to power down.

Another case of
people not knowing or caring enough to really understand, and simply
buying
blind eye, wishful confidence.


I think you may be FOS.

Ease up, Leon. Mike was referring to the brown out comment, not the
fact that non computer devices don't get a shut down signal.

My UPS by APC will not "brown out" as the battery runs down, it will
shut down instantly with no transient spikes or other damaging activity
when it can no longer supply full power to the UPS outlets.

So I agree with Mike - a ups that doesn't shutdown instantly when unable
to supply full power instead of browning out is nothing I would want
powering any device.




BTW, an easy way to determine if a UPS shuts down instantly or "browns
out" when there is a power outage is to plug in an incandescent light
into one of the UPS outlets and then uplug the UPS. After the battery
is unable to supply full power, the light should turn off instantly, not
dim over minutes or seconds.
