MT
= Message Type. This 2-digit sequence is used to identify the Contact ID
message to the receiver. It may be transmitted as either 18 (preferred)
or 98 (optional). New receiver implementations shall accept either an 18
or a 98. Note that some older receivers may not accept 98.
Q
= Event qualifier, which gives specific event information:
1 = New Event or Opening
3 = New Restore or Closing
6 = Previously reported condition still present (Status report)
XYZ
= Event code (3 Hex digits 0-9, B-F)
GG
= Group or Partition number (2 Hex digits 0-9, B-F). Use 00 to indicate
that no specific group or partition information applies.
CCC
= Zone number (Event reports) or User # (Open/Close reports) (3 Hex
digits 0-9, B-F). Use 000 to indicate that no specific zone or user
information applies.
