RB-LPU40014 Replacement Interference Board for IRONCLAD System
Product Description
RB-LPU40014 Replacement Interference Board for IRONCLAD System
The RB-LPU40014 is the foundational Replacement Interface and Surge Protection Board for the RBtec LPU-400 Series Fence Alarm Processors (LPU-402 and LPU-404). This board is the vital front line of defence, providing the essential connection points and robust surge protection for the IRONCLAD Perimeter Intrusion Detection System (PIDS).
Key Features and Benefits
Superior Surge Protection: Designed with an integrated two-layer surge protection circuit on all inputs and outputs (including sensor cables, power, and relays). This feature is crucial for protecting the sensitive internal electronics—like the CPU and Power boards—from damaging lightning strikes and high-voltage transients common to outdoor perimeter installations.
Master Wiring Interface: Serves as the centralized terminal point where all external system wiring connects: up to four sensor zones, all alarm relay outputs (intrusion, tamper, power loss), and the primary power input. Clearly marked terminals ensure efficient, error-free wiring.
Designed for Repair: In the event of a severe lightning or surge event, the RB-LPU40014 is engineered to absorb the damage, acting as the primary sacrificial component. This allows technicians to replace only this board, significantly reducing repair time and costs compared to replacing the entire processor.
Direct Replacement: Fully compatible with the LPU-400 Series, this board guarantees a direct fit and seamless functionality restoration, maintaining the robust reliability of your RBtec security system.
Note: This is an accessory/spare part and not a complete system. First Fence offers a line of IRONCLAD single and dual zone kits, rolls of sensor cable in 75m, 150m and 300m lengths, and complete analyser kits for 2 zones and 4 zones.
