Safety Bus system

The Safety Bus system allows the fire detection and the firefighting control in a unique bus assuring a high safety level. The system is composed by one or two control cards that are integrated in the panel H-S81-HS, and up to 64 addressable remote modules installed in the field. The communication between the control cards and the addressable modules is based on CAN protocol (Controller Area Network) with ring architecture to guarantee the best functionality in fault condition and high communication speed. This module can control eight 4-20mA analog inputs with safety-related functions. All the channels are continuously tested during operation.

The following types of transducers can be connected to this board: Explosive gas detectors, Toxic Gas Detectors, Oxygen sensors, Temperature Sensors/detectors, Flame Detectors, 4-20mA generic Sensors/Detectors. Each channel features dedicated terminals to supply 24V DC power to field device. Both communication links are provided with short circuit isolator. Alarm on three individually programmable thresholds:-Combustible, toxic, and oxygen gas detection.
