The I8 W4G device is a modern contact-controlled remote monitoring communicator operating in parallel on the WIFI and 4G mobile networks,
which generates an event for a change in the status of the input contacts (NO or NC) and sends it to the configured remote monitoring receivers.

Another advantage is that it can connect to a service server (IoT) server in the background, which allows continuous remote access to the communicator via a WEB browser.
Thanks to this, even the connected alarm can be remotely accessed, configured and programmed at any time.

The so-called ERPWDN (automatic power disconnection unit) has been built into the product, of course, in addition to the external restart circuit (wachdog) of the microcontroller
which eliminates the phenomenon of freezes caused by network errors. When a fault is detected, an independent circuit will de-energize the unit for about 5 seconds, ensuring a restart.
