The 'whole house' protector is your only solution. That UPS has surge protection. Then view the number. Protector is as close to zero as possible and still claim surge protection. Anything that protects next to an appliance is already done inside the appliance. Installing near zero protection increases sales among the many that learn only from myths.
Also bogus is the warranty. In simplest terms, the greater that warranty, the worse that product. If warranties say anything about quality, then GM cars are obviously superior to every Honda and Toyota.
Protection is always about where energy dissipates. Always. Any recommendation that does not discuss where energy dissipates is wasted energy. Either energy dissipates harmlessly outside the building. Or that energy is inside hunting for earth destructively via appliances. UPS makes no difference.
Every appliance already has superior protection. Energy permitted inside the building can overwhelm that protection. Will it destroy everything? Of course not. Energy hunts and chooses the better path to earth.
To claim that UPS did protection means everything else in the house must be damaged. Or do you also have invisible UPSes? How much electronics is inside also makes no difference. Some of the most robust appliances are computers - required to withstand at least 2000 volts without damage.
Any protector that failed did no protection. How to sell the worst protectors for highest prices? Grossly undersize it. A surge too small to overwhelm protection in electronics can destroy a protector. Then the naive will recommend that ineffective protector rather than learn how protection works.
Earth a 'whole house' protector to remain functional even after a direct lightning strike. A direct strike to wires down the street are a direct lightning strike to all electronics. Lightning is typically 20,000 amps. So a minimally sized 'whole house' protector is 50,000 amps. More responsible companies such as General Electric, Square D, Keison, Intermatic, Siemens, and Leviton provide them. A Cutler-Hammer solution is sold in Lowes and Home Depot for less than $50.
Now, no protector is protection. Yes, these many concepts well understood 100 years ago are probably so new that you must reread this at least three times. No protector is protection - no matter how many lie about it. The NIST (US government research agency) says it best:
> A very important point to keep in mind is that your surge protector will work by diverting
> the surges to ground. The best surge protection in the world can be useless if

That UPS has no earth ground. Its own numeric specs claim no protection from each type of surge. Two of many reasons why UPSes do virtually no surge protection. Legal is to lie in the sales brochure. And as demonstrated here, many will believe the lies rather than first learn what does protection.
Protection is always about where energy dissipates. That means a protector connects short (ie 'less than 10 feet') to earth ground - or does nothing. Sometimes the ineffective plug-in protector can even earth a surge destructively via some appliance elsewhere in the room. Yes, plug-in protectors sometimes make damage easier. Why? "The best protection in the world can be useless if grounding is not done properly."
Due to retail myths, most will never understand this if it is not repeated constantly. Protection is always about where energy dissipates. A protector is only as effective as its earth ground. You need a 'whole house' protector to even protect undersized power strip and UPS protectors. You had damage. That means you had no surge protection. That surge was inside hunting destructively. Protection is determined by the most critical component in every surge protection system: single point earth ground.
Protection is always about where energy is absorbed. Therefore every protection layer is defined by the only component always required in every layer - single point earth ground. A protector is only as effective as its earth ground.
