APPENDIX-K: DRIFT COMPENSATION
The H-Series optical detector cannot implement drift compensation on its own. Drift
compensation is the panel’s responsibility.
While the system is running, the detector sends its chamber real-time values to the panel
periodically and does not do compensation by itself.
For the first hour after a panel startup, the panel will check the detector chamber values every
10 minutes. After that, the panel will check the chamber reading every 24 hours. If the panel
detects the detector is a little dirty than before, it would send a compensation value to detector.
If a panel has detected that a detector has reached the upper limit of compensation, the panel
reports a “dirty” trouble. Otherwise the panel will continuously compensate the detector until it
reaches the upper limit.
