Affected versions
The CPSC notice identifies firmware version 11.2.2 for NFS2-640 and NFS-320 panels and firmware version 3.14.1 for NFS-640 panels.
Why it mattered
According to CPSC, the affected operating-system firmware could cause the panel to fail to process an alarm condition, creating a risk that building occupants would not be alerted to a fire.
Field check
Do not condemn a panel based on the model number alone. Confirm the installed firmware revision and compare it with the official recall information.
How to verify whether a panel is affected
The model number by itself is not enough. Access the panel information using the manufacturer's approved service procedure and record the exact firmware revision before comparing it with the CPSC recall. If the site has multiple networked nodes, document each applicable panel separately because revisions can differ from node to node.
Service-record details worth capturing
- Panel model, node identification, and firmware revision.
- Date the firmware was verified and the person/company performing the check.
- Whether the revision matches the version named in the CPSC notice.
- Manufacturer remedy or upgrade information used.
- Functional testing completed after any firmware or hardware correction.
Before returning the panel to normal
Follow manufacturer instructions for any firmware update and protect the site's program/configuration before making changes. After the remedy, perform the required acceptance or functional testing for affected functions and confirm that alarm processing, annunciation, notification, communications, and network operation are normal.
Identify the exact model, firmware, and date information before deciding the equipment is affected. Document what you find and follow the official source and your company's approved impairment/replacement process.
Official source
Always verify the current manufacturer or government notice before acting.
