At my parent's home Atlas installed a new alarms system 20 years ago with excellent service. In the same home we upgraded the system for a secondary suite that has been installed for 5 years. Since we have been very happy with Atlas, in my current home I had Atlas upgrade an old Birks Alarm system then has been running for over 5 years. Both homes are also monitored for smoke/fire too. Atlas has excellent service and even their staff over the phone is very knowledgeable and saved me on on-site service calls. Atlas has great equipment that is more costly and is not for everybody who have a tight budget. But IMO, they are the BEST!!
