The heart of your U-Prox system — 4G LTE, EN 50131 Grade 2, up to 250 sensors.

The U-Prox wireless alarm hub is the control and communication centre of your entire security system. It manages up to 250 detection lines, 30 keypads and 8 radio repeaters, communicates over two encrypted radio channels in two-way technology with all sensors and reports alarms over internet (LAN/WiFi) and 4G LTE — even during power and internet outages it keeps reporting.

What technically distinguishes the hub

Four highlights: EN 50131 Grade 2 certified for commercial applications with normal risk (homes, practices, small shops). 868 MHz narrowband radio with up to 4,800 m range in free field — the radio penetrates multiple walls without issue. Two-way communication with acknowledgement of every radio telegram — tamper- and jamming-resistant. Built-in 4G LTE with two SIM slots — if one SIM fails or network drops, the other carries on.

Power outage and backup

The hub has an integrated backup battery that keeps the installation running for hours during power outages. Including tamper protection (sabotage detection on enclosure and wall mount) and automatic status reports to the app and if applicable to the emergency monitoring centre.

Design and installation

Available in white or black, compact form (fits unobtrusively into any living space), fast wall mounting in under 30 minutes. 230 V power supply with backup battery — no separate UPS needed.
