Recently, the company's Exeter UPS is dead, so it's too much trouble to check it from time to time. If you want to recognize the fault, you can call the police by SMS. How to achieve it?

Axel's front panel will have a row of terminals after opening, which can receive alarm signals. But to realize SMS alarm, more equipment is needed, which is very troublesome. I'm here to buy the network card of Exeter UPS, set up the back network and send an email when calling the police.
