Yes. The alarm works in the same way as a standard landline telephone, so it will work alongside a broadband connection. You simply need to make sure you have an ADSL filter and this should already be connected to your main landline socket. If you need an ADSL filter and can`t locate one you should be able to request this from your current broadband or telephone provider. Your alarm will connect to either the “Phone” or “Analogue” socket in your ADSL filter, whereas your broadband will be connected to the “Modem” section. Using the phone adapter provided, you will be able to plug your telephone handset into the back of the alarm unit. This way, the alarm, your telephone and your broadband can work alongside each other.
