CPSC campaign 12721
Hazard
On all systems, when the alarm verification feature of the system is turned on, the control panel can fail to sound an alarm if a fire occurs. In addition, on systems with 50 or more reporting stations, a delay in sounding an alarm and reporting a fire may occur if the loop for the alarm system is broken.
Remedy
All distributors and installers are being sent two technical bulletins. One provides instructions for how to implement a software change that will correct the verification feature. The second contains instructions for how to handle warnings from affected systems with 50 or more stations. Those who have not received the bulletins should contact Bosch.
