FLN Network Strategies
Example for Oxygen sensor: Normally, there is 20.9% VOL of oxygen in
the air. It is good practice to detect when there is too much oxygen (ALR
HI FLAG) and when there is not enough (ALR LO FLAG). The ALR HI
FLAG works as described in the previous paragraph. However, for the
ALR LO FLAG, the MIN value must be higher that the MAX value for
proper use. This instruction tells the detector to use negative trig for this
flag (normally used when the alarm level is under the normal
concentration). In such a case, the current flag will be set when the
oxygen concentration is under the MAX level and is cleared when the
concentration rises above the MIN value.
Address
limitations The default value for CTLR ADDRESS (Point 1) is 99 - the
maximum address value allowed in the FLN specifications
