4100U Software Upgrade Program 

Software Upgrades Completed on Most Simplex® Fire Alarm Panels
Affected by U.S. Consumer Product Safety Commission Alert

Taking a proactive approach that reflects its long-standing commitment to safety, quality and customer service, SimplexGrinnell has completed software upgrades on most Simplex 4100U fire alarm panels affected by a software issue that resulted in a recent U.S. Consumer Product Safety Commission (CPSC) website alert. SimplexGrinnell has been contacting affected customers directly to arrange corrective software upgrades under a remediation program developed in cooperation with CPSC. The program is directed at a limited number of Simplex 4100U fire alarm control panels distributed from May 2010 to September 2010.

The software issue could potentially disrupt an affected panel’s ability to electronically alert a third-party alarm monitoring center of an alarm condition. Software upgrades have been completed at nearly all customer locations where affected panels are installed and connected to a third-party alarm monitoring center.

While the software issue can potentially affect outbound communication transmissions from an affected panel to a third-party monitoring center, it does not compromise the system’s ability to detect a fire or warn building occupants of an alarm condition via horns, strobe lights and other notification appliances. To date, SimplexGrinnell has received two reports of alarm conditions that were not reported to a third-party alarm monitoring center. No injuries were reported as a result of those incidents.

SimplexGrinnell will continue with the remediation effort until software upgrades have been completed on all affected panels, including those shipped during the May-September 2010 time frame but not yet installed at customer locations. 

“SimplexGrinnell and Tyco Safety Products take our responsibilities as leaders in life safety and property protection very seriously,” said John Haynes, Director, Fire Alarm Marketing. “We took a proactive approach by voluntarily informing the Consumer Product Safety Commission of the software issue. We have worked diligently on the remediation program in order to support our customers and inform the public. Our intent is to expeditiously fulfill our commitment to complete software upgrades at no cost on every affected panel.”

The potential for the software issue to impact customers outside the United States is very limited.

The software issue affects outbound alerts transmitted through a 4100-0155 or 4100-6052 DACT (Central Station Communication Device) – modules used primarily in the United States to enable Simplex panels to report to third-party alarm monitoring centers.

The affected panels are more fully described as follows: Simplex 4100U-NXP panel configured for third-party monitoring and running software revision 14.01. The words “Simplex,” “4100U” and “Fire Control” appear on the front panel. The software revision number can be identified by pressing the “Menu” key on the panel keypad, selecting “Show Software Revision Level” and pressing “Enter.” Only panels with the 14.01 software revision number are affected.

All 4100U panels shipped since September 2010 are equipped with the updated software revision that resolved the problem.

Any customer with questions, including those with software revision 14.01 who may not have been contacted directly, can call SimplexGrinnell at the toll-free remediation program line that has been established: (866) 565-6322.
