Tyco Fire Protection is recalling about 750 Simplex 4100ES Fire Alarm Control Panels due to a defective chip. This defect can cause the backup battery to fail prematurely and prevent the system from activating alarms, sirens, or voice communications during an emergency. These professional-grade panels were sold in red or white metal cabinets between 22 and 56 inches tall and were distributed to customers by SimplexGrinnell between March and June 2014. SimplexGrinnell and Tyco are contacting known purchasers directly to inspect and replace the faulty circuit boards at no cost.
A defective internal chip can drain the system's battery unexpectedly and block the panel from sending signals to fire alarms and emergency speakers. This failure means the system may not alert occupants during a fire, significantly increasing the risk of serious injury or property damage.
SimplexGrinnell is inspecting and replacing all circuit boards with the defective chip. SimplexGrinnell and Tyco are contacting purchasers directly.
