Autronica bu-70 Fire Alarm Control Panel

Autronica BU-70 is a remote display unit for AutroSafe fire-detection systems that presents alarm zone text and system status from BS-100 panels to on-site operators. It connects to AutroSafe panels via RS-232 using the AutroCom protocol; a BU-70 interface module (BSL-337) translates the AutroSafe data into ASSP (Autronica Standard Short Protocol for BU-panel communications) so BU-70 displays, BU-100, and BU-101 units can share the same event information. The BU-70 is intended for distributed annunciation in facilities that deploy BS-100 systems, enabling multiple BU-70 display units to show the active zone text from a single panel or from BU-100/BU-101 parallel operation panels. As part of Autronica Fire and Security's BU-series, the BU-70 interacts with AutroSafe panels and BU-panel devices to convey alarms, pre-alarms, and faults in real time, helping operators identify where action is needed. Typical installations include control rooms, operator desks, or other semi-public areas where staff require immediate visibility of the active zone and event details. The system’s architecture—using RS-232 AutroCom communication and the ASSP BU protocol—enables scalable annunciation across multiple display units while preserving consistent event data across the AutroSafe environment.
