This wireless receiver for the M1 series panels will allow you to use Honeywell's 5800 series. This way if you upgrade your Honeywell Honeywell panel to an ELK panel, you won't have to buy new wireless transmitter and devices. A lot of people balk at the idea of even switching alarm systems for this exact reason.
The ELK-M1XRF2H will not only allow you to use 5800 series wireless devices, but it also will give you an extra 144 wireless zones as well. You can also use a number of these in varying places in your location to extend the range of coverage you get for your wireless devices.
