This normally indicates that the detector is set at an Alarm Factor inappropriate for the installed

environment.

Increase the Alarm Factor to reduce sensitivity.

The sensor chamber may be contaminated.

Return the detector for factory cleaning and recalibration.

.2 Detector Will Not Pass Smoke Test

Detector may be in a FastLearn cycle.

Check if green OK LED is on and flashing.

The detector FastLearn cycle may have been carried out during, or immediately after, a smoke test.

Reinitiate FastLearn with the detector in a clean environment.

The Alarm Factor is too high.

Change the Alarm Factor to a lower, more sensitive, setting.

.3 Nuisance Flow Faults

Flow monitoring is too sensitive for the environment.

Increase the flow limit offset.

Airflow may be subject to temporary changes (spikes).

Increase flow fault delay.
