Ever since 1983 the telephone alert specialist

We have been supplying our telephone alarms and modems for monitoring critical processes and installations since 1983. We are proud of these products and their long lifespan. As a guideline, you can assume that the reliability decreases more quickly with alarms older than 10 years. Depending on the conditions of use, this may even be earlier. For information about lifespan, repair or service, please refer to the service page.
