Local Processor Unit (LPU-402 Analyser) with 2 Relay Output
Product Description
Local Processor Unit (LPU-402 Analyser) with 2 Relay Output
A local processor unit is the intelligent engine powering reliable perimeter defence. The RBtec RB-LPU402 is the advanced digital processor board that forms the electronic core of the IRONCLAD Perimeter Intrusion Detection System (PIDS). Engineered for precision and resilience, this unit analyses vibrational data to deliver highly accurate, segmented security for medium-sized perimeters.
Key Features and Performance
Dual-Zone Precision Monitoring: The LPU-402 efficiently processes signals from two independent runs of IRONCLAD sensor cable, managing up to 600m/2,000ft total fence line. This dual-zone capacity allows for critical perimeter segmentation, ensuring rapid and accurate location of any intrusion event.
Superior False Alarm Immunity: Features advanced 3-layer surge protection and digital filtering to distinguish real intrusion events from environmental noise, ensuring high reliability with minimal false alarms.
Flexible Sensitivity Control: Provides 22 discrete sensitivity levels adjustable directly via on-board jumpers (DIP switches) for fast, easy field tuning. For advanced installations, up to 500 sensitivity levels are accessible via PC software connected through the USB-C port.
Universal Integration: Equipped with multiple dedicated dry contact relay outputs (including separate relays for Zone 1, Zone 2, Tamper, and Fault) allowing connection to virtually any existing security system, including alarm panels, VMS, NVRs, and SCADA systems.
Ideal Applications
Medium-Sized Commercial & Industrial Facilities: This is the primary market for a dual-zone system, balancing cost with accurate coverage.
Critical Infrastructure (Smaller Sites): For installations that need high reliability but don't require miles of coverage.
Residential or High-Value Properties (Estate Security): Where a complex perimeter needs segmentation for surveillance camera direction.
Note: This is not a complete kit, this is an accessory/spare part.
