In Table 5, the greyed section indicates flow rate recording while the white
section indicates detector and alarm level recording.
The factory default setting is 8. At the slowest recording rate, one month of data
can be recorded. A PC must be connected via the RS-232 port with appropriate
software to view the chart event log. (See “Connecting to a PC” on page 35 for
details on how to connect to a PC.)
User defined access code
0-9999 - Address 000-127: This function sets the access code that the user has
to input in order to modify any of the function values. The default setting is “0102”
but for added security it can be changed to any four-digit number desired by the
user.
Bms protocol
0-2 - CM only: This function sets the communications protocol for connection to
a Building Management System (BMS). (See Appendix A for details on how to
set up external communications.)
Factory default
Yes/No - Address 000 - 127: On the standard detector, this function has two
purposes. If the user has changed any of the detector’s functions, this function
will display No, indicating that the detector is not at factory default. Setting the
function to Yes will restore the detector to the factory default settings. On the
command module, this setting returns all detectors on the communications loop
to their default settings. To default an individual detector in the loop, it is
necessary to use the detector’s own front panel.
