C-CURE 800 uses a general purpose bi-directional serial interface to provide advanced, seamless integration with the 4100U fire panel from SimplexGrinnell, allowing customers to monitor their important fire devices from the C-CURE 800 guard station. The SimplexGrinnell 4100U Fire Panel is a high-end, next-generation distributed network system that combines superior fire protection and information management with lower costs of installation, maintenance and ownership. The union of this high-end fire system and the C-CURE 800 through a bi-directional interface provides extensive system integration opportunities, including the ability to receive secondary annunciation from the linked fire alarms. Currently, the 4100U Fire Panel can support up to 2000 signals through a centralized RS-232 connection. This allows security personnel to view all critical events, including access violations, video alarms, and now fire alarms, from one centralized station. As per fire regulations, no control is provided for the security system operators to silence alarms or reset signals to a cleared state on the fire system. As with other important events in the C-CURE 800, all fire alarm activity is stored in the system's detailed journal for future investigative reporting.
