A four second transfer time is way too long by at least an order of magnitude. There is no way the power supply in a PC can maintain for that long a time.
If you are in a real critical environment I would recommend going to a UPS which runs continuously and runs off a battery which is charged whenever utility power is available. That way there is no transfer time.
These offline units are harder to find however.
I suspect your UPS system is defective.
my ups is not providing any power even if main power is on. Can anybody plz tell me where does i have to check for the faults very first
