HUB2

Paradox HUB2‑E9R Hub & Bus Isolator

The HUB2‑E9R is a specialised hub and bus isolator module designed for Paradox Spectra and EVO alarm systems. It enhances system reliability by splitting sensor and accessory communications into independently isolated channels.

🔑 Key Features

• Dual-Isolation Function: One input port feeds two independent output buses.

• Fault Resilience: If one bus segment fails or is shorted, the other remains fully operational.

• Extended Signal Range: Each isolated bus supports up to 900 m (3,000 ft) of wiring.

• Seamless Integration: Designed for use with Paradox Spectra Plus and EVO panel series.

• Efficient Form Factor: Compact board-only module suitable for clean system integration.

⚙️ Technical Specifications
