When the TC-9100 Universal Controller is supervised by an N2 Dial
Module (Order Code NU-NDM101-0), the N2 Dial Module will initiate a
telephone dial-up connection to a central monitoring station (such as a
Metasys NCM or Companion System) whenever it detects that the DIAL
Bit (Item XST, Address 84 hex, Bit 5) is set. When the connection has
been successfully completed, the central monitoring station will reset the
DIAL Bit.
The DIAL Bit is set by the conditions shown in Table 22 below. Note that
the bit is set by a
change-of-state
to the alarm or off-normal condition,
and when it has been reset by the central monitoring system, it will not be
set again until a different change-of-state occurs, or the same condition
returns to normal
and
then changes again into the alarm or off-normal
condition. The return to normal change does not set the DIAL Bit.
