iii Compatible Loop Devices and Panel Responses
The following table shows all devices compatible with the panel. It shows the panel’s response to events from each device type, and indicates the change in
analogue value and input bits that will be displayed in the status mode. Note that some device types automatically receive cause effect outputs by default. Any such
programming is indicated in the default cause and effect column.
