The ALSTOM AUTRONICA BSB-310A is a specialized I/O module designed for the AutroSafe interactive fire detection system. It provides four independently monitored output circuits for controlling alarm sounders, fire protection equipment, and routing devices. The module features automatic addressing and galvanic isolation between internal system power and external output power, ensuring high system integrity. When used as a spare part to replace legacy BSB-310 units, it integrates seamlessly onto the mounting rail of the fire alarm control panel, providing real-time diagnostics for circuit breaks or short-circuit conditions.

 

Product Q&A

Q1: What is the primary function of the monitoring feature in the BSB-310A? A1: The monitoring feature continuously checks the integrity of the connected cables. It can distinguish between a normal state, a “break” (open circuit), or a “short-circuit,” allowing the fire alarm panel to report precise fault locations instantly.

Q2: Does the BSB-310A require manual address setting via dip switches? A2: No, the BSB-310A supports automatic addressing. The I/O module automatically detects its own address when plugged onto the mounting rail, simplifying installation and reducing the risk of manual configuration errors.

Q3: Can the output circuits handle inductive loads like solenoids? A3: Yes, but it is required to use a protection diode at the load for inductive applications. Each output is fused with a 1A self-resetting fuse to protect the module against overcurrent.
