27.1
Disconnect / Re-connect COM loop (H8/S1)
To avoid damage on the units and FT128 during physical connection / disconnection of
loop units, it is highly recommended to have the loop disconnected (disabled), i.e. the loop
is voltage free (dead). Zone line input requires an 8 zones expansion board 4580 in the
control unit or an Addressable multipurpose I/O unit 3361/4461 connected on a COM loop.
One or more disconnected "loops" are indicated by LED “Disablements", the LED “Service”
is flashing, and disconnected loops are listed in menu H4/U1.
Note: When you disconnect and re-connect the COM loop, all the statistics shown in
menu H5/A6 will be erased and set to "0".
