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.
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.
