Mountain Alarm Acquires A-1 Security Systems to Expand Our Colorado Operation

Mountain Alarm is proud to welcome the newest addition to the family–A-1 Security Systems in Denver, CO. After many years in business, the owners of A-1 Security Systems decided to retire and have entrusted us to take over their operation.

The coming year will mark Mountain Alarm’s 70th anniversary, still owned and operated by the founding family. We look forward to providing these newest customers with an unparalleled service experience, while offering them new, innovative solutions and services for all their fire and security needs.

Over the course of the next several months, A-1 customers will notice some of these new features available at no charge, including automated low-priority signal notification, Alarm Chat feature, and three redundant 5-Diamond UL-listed central station monitoring centers.

For convenience and continuity, we will continue to maintain A-1’s same number–(303) 462-2443–for sales, service, central station, and customer service. However, all of our Colorado operations will be conducted from Mountain Alarm’s current location at 7276 W. Mansfield Avenue in Lakewood, CO.

If newly acquired customers have any questions, please call the local office at (303) 462-2443 or our corporate headquarters at 1-888-349-3455. We look forward to serving you and are grateful you’re now part of the Mountain Alarm family.
