Bosch GV4 Fire Alarm Control Panels
Check against the official notice below — it lists the full affected range.
Bosch Security Systems is recalling G-series Fire Alarm Control Panels with model numbers ending in GV4 that use D192G Notification Appliance Circuit modules. These professionally installed panels, which have model numbers D9412GV4, D7412GV4, or D7212GV4, can fail to activate audible or visual alarms in the event of a fire because the NAC module does not properly monitor circuit connections and signal alarm failures. The panels are used in both residential and commercial facilities and may be installed in various enclosures.
Consumers who have a recalled GV4 control panel with a D192G NAC module should contact Bosch or their certified professional installer for a free repair. Bosch has already notified distributors and installers and provided service bulletins with instructions on how to correct the problem.
