Notes.
The 32 inputs are numbered 1 to 32 in section 3.2.3.5, corresponding to the
associated pin on the 40 way input connector, however the handset command
numbers the inputs from 0 to 31, for the 32 inputs.
This facility is included in PB391 issue 2 firmware (and above).

TC12 Installation, Commissioning & Maintenance Handbook
Used to select the DFM time limits set up by GMA and GMI for the
input specified. The default value for all inputs is 255, which
indicates that no DFM is required on those inputs. To start the
monitoring of an input, use this command to allocate an input to a
DFM group. Although any value above 7 disables monitoring, it is
suggested that only 255 is used.
Setting this value to a valid input number (i.e. 0 to 31) provides a
lamp test facility (for use with a green wave box). If the allocated
input is active (i.e. "1") then all the OTU output relays are
energised. The default value is 255 - lamp test facility disabled.
