3.6 MX4428 PROGRAMMING
In the following sections information is given about the programming of each device in the
MX4428. An explanation of the mode and the various parameters is given for each device
type, along with the global parameters that affect that device type. It is critical that only the
listed mode values are used for each device type, as in many cases the mode value is used
to define the actual device type. An incorrect mode value may cause a POINT TYPE
MISMATCH to be generated, or it may just render a device not able to work.
In some of the following sections descriptions are given about changing the sensitivity for a
detector by altering the specific parameter for that detector. This is correct (it sets the value
for just that individual detector), but in many cases it may be better to adjust the global
sensitivity for that device type so that all detectors of that type take on the new value. For
example, in NZ mode it is recommended that the global heat alarm temperature be set to
57
°
C for both 814PH and 814CH, rather than setting each specific detector to this value.
Details for NZ mode settings are contained in the F4000 NZ Technical Manual (LT0126).
These details are most relevant when programming the MX4428 from a (dumb)
programming terminal. Alternatively you can program with "SmartConfig", which displays
and edits functional parameters and takes care of mapping the functional parameters into
the appropriate mode and parameter bytes for each device type.
