5.4.8 Map Descriptor Example 3 – Zone Status as a numeric value
In this example, the driver stores zone data for any zone. It will store data for all possible states that the panel reports for each of the zones in the form of a
number in the Data Array. The number can be interpreted to determine which states are active.

This data type tells the driver that this Map Descriptor must be used to
store zone status data of any type.
The driver writes a number into the array location for each device. The
value of the number indicates the status of the zone. The value is
based on which bits in the binary number are set.
Bit 0: Abort State
Bit 1: Trouble State
Bit 2: Supervisory State
Bit 3: Zone is disabled
Bit 4: Pre Alarm State
Bit 5: Alarm State
Bit 6: Pre-Discharge State
Bit 7: Release State
Bit 8: Process State
Example : Value = 32 indicates an alarm state
Example : Value = 96 indicates an alarm & pre-discharge state
For the driver to effectively report the
status as a number the Data Array format
must be suitable for storing the number.
UINT16, UINT32 and FLOAT formats are
supported.
