The Gamewell-FCI E3-INX-DPLATE, Mounting plate that aligns INX sub-assemblies inside D-size cabinets. For distributed-audio transponder nodes with multiple amplifiers.

Mounting plate for D-size INX builds

The E3-INX-DPLATE provides the standardized mounting pattern for INX sub-assemblies, INI-VGX voice transponder, PM-9 power supply, AM-50 amplifiers, ANX node expander, inside a D-size cabinet (19.375 × 41 × 4.5 inches). The plate eliminates field improvisation: every module lands at a known position, with cable routing planned in.

When D-size INX is required

D-size INX builds extend the standard C-size INX (up to 4 AM-50 amplifiers and one PM-9) to fit more amplifiers, larger battery capacity, or additional switch banks. Typical use: distributed-audio risers in high-rise buildings where one transponder serves many floors; large industrial campuses with single-cabinet density requirements.

Construction and listings

Steel plate matching the D cabinet interior. Mounts with standard cabinet hardware. Listed as part of the E3 Series Cabinets per 9020-0649 revision X, under the same UL / FM / MEA / CSFM approvals as the parent cabinet.

Specify with the parent E3 cabinet

Order alongside the matching E3 cabinet, inner door, and mounting hardware to keep the assembly under one listed configuration. Confirm the current Gamewell-FCI part-number cross-reference and revision against the 9020-0649 cabinet datasheet before specifying for jurisdiction-sensitive projects so that the as-built record matches the published listing matrix.
