Interstate Alarm Company Story

In the early 1970s, after getting out of the Navy and working for Seattle-based Grinnell-ADT, Butte-born “Spike” McQuiston wanted to get back to his roots. So he returned to Montana, settled in Missoula and joined together some partners to start an alarm company/answering service/locksmith shop. In 1972, Interstate Alarm Company was incorporated. Over the years, the locksmith shop went away and one of the partners moved his family into a small office to run the 24-hr answering service, which also responded to the alarms. Spike traveled the state, hauling a fifth wheel behind his truck, selling and installing alarms, building the company during a time that alarm systems were not commonplace. Eventually the answering service was sold and the alarm receivers were moved to the new answering service where they remained for many years.

 

When Spike passed away suddenly in 1993, his widow, Lynn, stepped in as the president and CEO of the company. Lynn's sons, Shawn and Josh, have now joined the business and will carry the company’s tradition of providing quality products and customer service into the next generation.

 

In 1995 we moved the now-computerized monitoring equipment to our office, hired operators, and provided 24-hr alarm monitoring for the next ten years. To comply with ever growing regulations for monitoring of fire systems, in 2005 we made the decision to upgrade our customers to a UL certified facility where we are today. In 1998, we purchased another alarm company in Kalispell and entered the extensive custom-home market in the Flathead valley.

 

Over the years the company has grown steadily and we believe that it is because we have provided quality equipment, installations, and customer service that is unmatched by our competition. Proof of this lies in the fact that we still have customers with us today that began with us in 1972.
