@EMER
Use
This command identifies the emergency priority level indicator. The @EMER command is typically used in one of the following situations:
- To test if a point is currently at emergency priority, an IF/THEN/ELSE statement would look like the following:
300 IF (SFAN.EQ.@EMER) THEN ON(HORN)
- To command a point at emergency priority, the program code might look like the following:
500 ON(@EMER,SFAN)
- To release a point in the device from emergency to PPCL priority, an example of program code might look like the following:
700 RELEAS(@EMER,SFAN)
NOTE:
Using the @ priority indicator in this manner will not release the point if it has a higher priority (SMOKE or OPER).
Notes
- For APOGEE and pre-APOGEE firmware, if the @ priority indicator is not used, the automation station will release points from PDL or EMER priority to NONE.
- For BACnet firmware, the automation station releases the slot corresponding to EMER in the Command Priority Table. The value of the point is set based on the highest slot in the Command Priority Array; relinquish default is used if the Command Priority Array is now empty.
