ALARMS
BACnet slave devices such as the SMART-Space Controller cannot broadcast alarms. For
this reason, Control-BASIC statements such as ALARM, DALARM, ALARM-TYPE, and ON-
ALARM are not implemented.
To generate alarms based on conditions monitored by an SSC, Control-BASIC alarm code
can be written in a BACnet master device to generate alarms based on the status of points
monitored in the SSC. In the following examples, SSC variables are used to communicate
alarm states to a host controller, which in turn generates the actual alarms.
SHARING OBJECTS
BACnet slave devices cannot request object information from other BACnet devices. For a
SMART-Space Controller to receive network objects, or Net-Ins, one of the following three
Control-BASIC statements or functions must be used: 1) standard command statements;
2) SHARE function; and 3) SHARE-NET function. A single SMART-Space Controller can
receive no more then 16 Net-Ins.
STANDARD COMMAND STATEMENTS
Control-BASIC in any Reliable Controls device on the network (except a MACH-Air, MACH-
Zone, or SMART-Space Controller) can be used to write to objects in an SSC. For example,
the following Control-BASIC lines could appear in a Reliable Controls device with a
schedule named OCC-SCHED, an analog input named AH1-OAT, and a binary variable
named AH1-SF-S.
Example 1: Code written in the SSC
10 FC1-SF-ALM = TIME-ON( FC1-SF AND NOT FC1-SF-S ) > 00:00:30
20 FC1-Rm100T-ALM = SWITCH( FC1-Rm100T-ALM , FC1-Rm100-T , 17 , 15 )
Example 2: Code written in MACH-ProCom host of SSC
10 DALARM FC1-SF-ALM , 30 , FanCoil #1 Supply Fan Failure
20 DALARM FC1-Rm100T-ALM , 30 , FanCoil #1, Rm100 Low Temp Warning
