Since 1983 Adésys has supplied telephone alarm detectors and modems for monitoring critical processes and installations. We are appropriately proud of the high level of reliability and long service life of our products. That is why we want to inform you well about the life span of our equipment. After all, it is extremely important that the products continue to perform optimally.

As a guideline, you can assume that the reliability of alarms older than 10 years will decrease at an accelerated rate. Depending on the conditions of use and the impending changes in the telecom networks, this may even be sooner. It still works' should not be a reason to monitor your assets worth tons or perhaps millions with equipment that may be 15 years old or more.
