1. Message type
S: Status for section: the number of faulty and activated condition reported as number in field 6.The section
may be a whole section (one or both of the division indicator fields are null) or a sub-section. The status S
is normally transmitted at regular intervals. Examples of use are given in Annex E.
E: Status for each detecter. (E may be used to indicate an event.)
F: Fault in system: Division indicator fields defines the section when provided.
D: Disabled: Detector is manually or automatically disabled from giving fire alarms.
2. Event time
Time of condition change or acknowledgement. This may be a null field.
3. Type of fire detection system
The field is two fixed characters, see table below.
4. First division indicator
First division indicator where detector is located. This field is two characters, see table below.
5. Second division indecator
Second division indicator where the detector is located. This field is three numeric characters, see table below.
6. Fire ditector number or activation detection count
This field is three fixed numeric characters. When the message type field is E, this field identifies the detector.
When message type field is S this field contains the number of detectors activated. When the message
type field is F or D this field is null.
7. Condition
When the message type field is S this field should be a null field. When the message type field is E, F or D this
field includes a single character specified by the following:
A = Activation
V = Non-activation
X = Fault (state unknown)
8. Alarm's acknowledgement state
When the message field type is E or F this field includes a single character specified by the following:
A = acknowledged
V = not acknowledged
When the message field type is S or D this shold be a null field.
9. Message description text
Descriptive text/sensor location tag. If a sensor location identifier is string type, it is possible to use this field instead
of above sensor allocation fields. Maximum number of characters will be limited by the maximum sentence
length and the length of other fields.
