Product Identity: Honeywell Model FS7-2173 (all variants)

Description: Flame Detector

FM Approval Status: All models bearing the FM mark.

Hazard Involved: Honeywell has discovered a small number of the FS7-2173 flame detectors in the field that would fail to respond to a fire condition as they are intended. In some cases, the detectors in question did not detect and annunciate the failed condition. The problem has been traced to a failed optical sensor within the detector, and a self-test algorithm that is not sensitive enough to detect the condition.

The company is still investigating the root cause of the failure and has temporarily withheld further shipments of the product. End users are requested to test all installed FS7-2173 detectors with the test lamp and report the Pass / Fail information to the contact listed above. In the event of a failure of the test, end users are also requested to contact the local Honeywell Gas Analysis & Safety office to initiate the RMA returns process. The details can be found in the attached Product Notice 2020106.
