 00 Great service on every encounter with Security Alarm of Salem, Illinois. The latest example occurred yesterday as service manager Erin listened to my explanation of our fire alarm problem and understood the urgent need of repair.Technician Joe Morrison quickly arrived at our Cila and demonstrated why the problem was some where other than the fire alarm equipment. He explained it in a manner this old man ( me ) would understand.Many THANKS to all involved, especially Erin and Joe.
