About ASI

We specialize in protecting commercial and residential customers with the latest products and technologies in the security and alarm system industry.

And we do it better than anyone else.

Since 1974, Alarm Systems Inc, ASI, has been one of the most experienced commercial and home security companies in the Midwest. Every client is provided with innovative solutions, quality craftsmanship and complete satisfaction. 

With a UL listed Central Station, alarms are monitored and responded to for intrusion, fire and other emergency situations. Adhering to such rigorous standards assures you of greater reliability and faster response when you need it most. 

As a Honeywell Platinum Level Certified Integrator, the highest level in the industry, it’s well known that we’re committed to excellence. This level of certification is reserved for only the highest level of expertise in Honeywell enterprise level products and systems. It also means a continual investment in training and certification for our sales staff, engineers and technicians. 

Each and every installation and service technician, is a professionally trained and certified, full-time ASI employee. All are knowledgeable and undergo continuing education in order to implement the best practices in the security industry. Even though only the latest innovative products are used for every client’s home and business, complete satisfaction remains a top priority. 

In 2016, after nearly 45 years of continued success, an opportunity to expand into southern Wisconsin developed with the acquisition of Associated Technical Services (ATS) and Southern Musicast. ATS began in 1984 and became southeastern Wisconsin’s premier sound and security systems integrator. Current ATS and ASI clients have benefitted from the combination of all of these service and product offerings, for a greater overall experience as well as an expanded coverage area.

As business clients have experienced continued success and growth with multiple locations into a variety of states, it’s our goal to partner with you on your journey to expansion. 

Services are available nationwide without any geographic boundary limitations.
