How does wireless interlinking work in FireAngel alarms?

If you choose not to add a Gateway upon initial installation, you can add a Gateway to an existing network at any time in the future – this will allow for remote monitoring of devices as the Gateway will communicate with the FireAngel App using an internet connection, however, if the internet connection fails or cuts out the alarms will still continue to work and protect property, no internet connection means you will no receive any push notifications whilst the internet is not working.
