Abstract
An improved life safety system provides ability to detect a catastrophic failure within a network node of the life safety system, and to subsequently pass a failsafe alarm signal through a network node, and through the life safety system, despite the catastrophic failure, which may be a failed main processor of a main panel, a failed main processor of a loop expander module, a failed main processor of an amplifier, or a failed main processor of a liquid crystal display controller.
