Syntax

@SMOKE

Use

This command identifies the smoke priority level indicator. The @SMOKE command is typically used in one of the following situations:

  • To test if a point is currently at smoke priority, an IF/THEN/ELSE statement would look like the following:

300  IF (SFAN.EQ.@SMOKE) THEN ON(HORN)

  • To release a point in the device from smoke to PPCL priority, an example of program code might look like the following:

700  RELEAS(@SMOKE,SFAN)

NOTE:
Using the @ priority indicator in this manner will not release the point if it has a higher priority (OPER).

NOTES

  • For APOGEE and pre-APOGEE firmware, the @ priority indicator must be used to release points from SMOKE, EMER, and PDL to NONE priority.
  • For BACnet firmware, the automation station releases the slot corresponding to SMOKE 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.
