“Tri State Alarm –
I wanted to thank you for your service. I rarely use my home alarm system. Actually, I planned to cancel it after my contract was up. Last weekend I was in Kansas City and my fiancé was at the house. He had an accident while prepping to clean a firearm. His cell phone was dead and he used the “Panic” on the alarm system to have police dispatched to the house. Your services saved his life. I am now a huge fanfor home security systems; they have so many uses. Thank you so much!
Sincerely, Amy”
