Optex BCU-4 Battery Common Unit for AX-TFRi and SL-QFRi Series Detectors

Maintain uninterrupted perimeter protection with the Optex BCU-4 battery common unit, purpose-built to provide centralized low-battery monitoring for photoelectric beam detectors. Designed as a paired module for the AX-TFRi and SL-QFRi series, the BCU-4 (manufacturer part number BCU-4) consolidates battery status from paired beams so security teams receive clear low-battery alerts before detection performance is compromised. This proactive monitoring minimizes false alarms, reduces emergency service visits, and keeps surveillance coverage continuous.

Engineered for seamless integration into Optex AX and SmartLine (SL) product lines, the BCU-4 supports standard wiring and monitoring workflows used by security integrators and facility managers. By centralizing battery supervision, it streamlines routine maintenance, accelerates troubleshooting, and enhances overall system uptime—critical for commercial, industrial, and institutional security installations. Ideal for perimeter security and facility monitoring, the BCU-4 complements photoelectric beam detectors and broader security systems.

Upgrade your surveillance infrastructure with the Optex BCU-4 to improve visibility into battery health and reduce operational risk. Add the BCU-4 to AX-TFRi or SL-QFRi installations for better monitoring and fewer service interruptions.
