Is a telephone needed for my Acticheck system to work?
You do not have to have a home telephone, or even a mobile.
However, it is better if you do as Acticheck designed the system phone you before calling your responders, as a check against false alarms and also to give you additional confidence that an alert is in process.
If you would like to skip this pre-alert check call please use 00000000 (eight zeros) as the first phone number and ‘save changes’.
