Junction box Hikvision Satel OMI-3 — white, 230 V, 50–60 Hz, 330×110×405 mm

Hikvision Satel OMI-3 is a white, surface-mounted metal junction box designed for indoor installation of electrical and security equipment. The enclosure accepts 230 V supply at 50–60 Hz and measures 330 × 110 × 405 mm, providing space for SATEL control panels, modules and expanders in multiple configurations. The unit includes an integrated AC/AC transformer (50 VA, 20 V AC, 50 Hz) and is supplied as one piece per pack. The OMI-3 meets EN 50131 Grade 3 requirements and is intended for use in applications where elevated physical security is required.

Advantages

The enclosure is made of robust metal and finished in white, offering mechanical protection and a neutral appearance for indoor environments. Built-in double tamper protection safeguards against both opening the cover and forcible removal from the wall. The integrated 50 VA AC/AC transformer with 20 V AC output simplifies powering compatible control panels and modules without requiring a separate transformer. Compliance with EN 50131 Grade 3 allows the box to be used in high-security alarm systems.

Suitable for

• Housing SATEL control panels, modules and expanders
• Alarm system installations requiring EN 50131 Grade 3 enclosures
• CCTV and access control equipment mounting and cable routing
• Indoor surface-mounted electrical and security devices

How to use

Mount the junction box on an appropriate indoor wall surface using suitable fasteners for the substrate and the enclosure weight. Route incoming 230 V supply and low-voltage wiring through the provided entry points or knockouts, following local electrical codes. Install SATEL control panels, modules or expanders inside the enclosure and connect them to the integrated transformer where a 20 V AC supply is required. Ensure tamper switches are connected and operational to maintain the double tamper protection functionality. After wiring, close and secure the cover to restore tamper protection.

Usage recommendations

Use the OMI-3 in installations that require higher physical security and compliant alarm hardware. Verify compatibility of connected devices with the integrated 20 V AC transformer and follow EN 50131 installation guidelines and local regulations when performing mounting and electrical connections.
