5 BACnet
5.1 General Information
Following information about DVP-1200 are accessible via BACnet.
1. Group Settings (Range, Alarm, Warning, Rising, Falling) for each type of sensor for all Zones.
2. Readings and Type for all detectors
3. Zone Configurations (Types of detectors assigned, Horn/Strobe Assigned, Relay Assigned, Analog Output Assigned,
Quorum for Voting Mode) for all Zones
4. Output status and values of DVP-1200 Outputs
Note: BACnet Objects with value 65535 indicates the value received is not reliable. Some of the possible reasons for such a
high value received are sensor not connected to panel, sensor is in trouble, or invalid/not supported BACnet object.
Operator must figure out the root cause of such readings.
For details on BACnet implementation or BACnet capabilities of DVP-1200, refer to DVP-1200 PICS available in product page
in company website (www.macurco.com).
1. Group Settings for each type of sensor for all Zones
Information about Group Settings for each gas type can be accessed via BACnet output in DVP-1200. Table 5-3 shows the
BACnet Object Type and Object Instance for each object. N in Table 5-3 refers to zone number. E.g. if I want to access the
Alarm settings for CO sensor in Zone 3, then Object Instance for the corresponding object is 3+ (3-1) * 68= 139.
Group settings are local to zone and hence each zone can have different settings for same type of sensor. Table 5-1 shows
the possible values for ‘code’ object and corresponding detector type. Similarly, Table 5-2 shows the possible values for
‘Eng.unit’ object and corresponding engineering unit.
