CPSC campaign 04507
Hazard
The AEU can enter a "sleep" mode, where it does not communicate with the system. When this occurs, audible evacuation signals associated with the failed AEU will not operate and building occupants may not be warned of an emergency.
Remedy
FCI will provide a new software chip set for each FireVac System, at no charge.
