When a UPS unit performs a delayed power off (NUT sets the delay to 20 seconds 
by default) it deconnects its power outlets which in some UPS units produces an 
audible "clunk".  The display of lights on the front panel changes, and the 
beeping stops.  The delayed power off can be demonstrated with a light bulb or a 
mains circuit tester connected to one of the UPS power outlets.

I looked at the product documentation at 
https://www.cyberpower.com/uk/en/product/sku/Value800EILCD and could find 
nothing about shutting down the UPS power outlets. Although the 800EILCD is able 
to turn off the beeper, this in itself is not sufficient. The proposed typical 
applications include NAS & Servers so it should be possible. Perhaps you could 
ask the Cyber Power support people if the 800EILCD has this function.

I see at http://networkupstools.org/ddl/Cyber_Power_Systems/Value_800E.html that 
the Value 800E does not have variables such as
  load.off.delay - Turn off the load with a delay (seconds)
  load.on.delay - Turn on the load with a delay (seconds)

What does command « upscmd -l <UPS> » report?
