Bosch recalls GV4 fire alarm control panels with D192G NAC modules that may fail to activate alarms during fires. Affected units have model numbers ending in GV4 and require free repair to prevent fire safety risks.
The notification appliance circuit module can cause the panels to fail to activate an audible or visual alarm in the event of a fire.
Bosch is recalling fire alarm control panels that use D192G NAC modules because they can fail to sound alarms during a fire. This could leave homes and businesses without warning if a fire occurs.
The D192G NAC module can fail to properly monitor alarm circuits, meaning the fire alarm system might not activate audible or visual alarms during a fire. This could prevent early detection of fire hazards, increasing the risk of injury or property damage.
Homeowners and businesses with professionally installed Bosch GV4 fire alarm panels that have model numbers ending in GV4 and use D192G NAC modules are affected. Those with panels in enclosed spaces larger than 16x16x3.5 inches are at higher risk.
Check for model numbers ending in GV4 on the panel board, such as D9412GV4, D7412GV4, or D7212GV4. The panels are used in homes and businesses and require a minimum enclosure size of 16 inches x 16 inches x 3.5 inches.
Reach out to Bosch or a certified professional installer for a free repair of the D192G NAC module.
