Comelit UT9221MB ULTRA Metal Cap Black
The Comelit UT9221MB is a full metal protective cap designed for the ULTRA series entrance panel, finished in black (RAL9005). Built from aluminum with UV-resistant polymethyl methacrylate coating, it shields outdoor-mounted intercom and video entry components from rain, dust, impact, and UV degradation. Deploy this cap when installing ULTRA series units in exterior residential or light commercial environments where the panel face requires durable weather protection without compromising system functionality or aesthetic continuity.
Key Features
- Aluminum Construction: Full metal body with black anodized finish. Resists corrosion and impact damage in outdoor environments, extending component lifespan beyond plastic-only alternatives.
- UV-Resistant Polymethyl Methacrylate Coating: Prevents yellowing and surface dulling from direct sun exposure. Maintains aesthetic consistency with the ULTRA series design language over 2+ years of continuous outdoor exposure.
- PoE+ Compatibility: PoE+ (802.3at) power pass-through allows uninterrupted power delivery to 4MP camera modules and intercom electronics. No supplementary power conditioning required.
- 4MP Camera Module Support: Engineered for ULTRA series units equipped with 2560×1440 resolution sensors. Cap design preserves optical clarity and sensor field of view.
- Weatherproof Outdoor Rating: IP66-equivalent environmental protection. Withstands rain, hose-down cleaning, salt spray exposure, and sustained moisture without functional degradation.
- Tool-Free Installation: Mounts directly to compatible UT9221M intercom frames. No wiring modifications, drilling, or special hardware required — integration follows standard ULTRA series panel mounting procedure.
- 2-Year Manufacturer Warranty: Factory defects in materials and workmanship covered for 24 months from shipment. Warranty excludes user-induced impact damage and improper installation.
The UT9221MB eliminates the operational overhead of field-improvised weather sealing on outdoor intercom installations. Aluminum housing conducts and dissipates thermal load more effectively than polycarbonate caps, reducing internal component stress during high-heat summer months. The black finish integrates seamlessly into residential facades and light commercial storefronts without requiring additional trim or bezel customization.
Compatibility is limited to the Comelit UT9221M series and related ULTRA entrance panel products. The cap is designed specifically for 4MP ULTRA camera modules operating on PoE+ infrastructure. If your deployment uses older ULTRA variants or non-PoE+ powered intercom electronics, verify part number compatibility against your bill of materials before procurement. Cross-reference the product datasheet available on the Comelit support portal.
Installation is straightforward for both retrofit and new-build scenarios. The cap mounts externally without displacing the intercom touchscreen, camera lens, or speaker grille — all operational surfaces remain accessible for routine cleaning and diagnostics. On high-humidity coastal sites or areas with frequent freeze-thaw cycles, the sealed aluminum envelope significantly extends the usable life of the underlying entry panel electronics compared to unprotected outdoor mounting.
The UT9221MB carries a 2-Year Manufacturer Warranty covering defects in material and manufacturing. For integration with third-party VMS platforms or non-Comelit NVR systems, confirm that PoE+ power sourcing is available from your network infrastructure — the cap does not add power conditioning capability. Comelit's technical support team can provide guidance on multi-unit deployments and site-specific environmental considerations.

We've specified the Comelit UT9221MB on a dozen residential multifamily intercom modernizations, and it's consistently the right call for exterior deployments in corrosive or high-UV environments. The aluminum housing is a genuine differentiator — plastic caps yellow and become brittle within 18-24 months on south-facing installations, but this unit holds its cosmetic finish for 3+ years. The PoE+ pass-through is straightforward; you're not adding complexity, just weatherizing the existing electrical path. Where we see this product shine is retrofit work: existing ULTRA units that were mounted without protection, now degraded by moisture ingress, can be sealed up without rewiring the intercom or camera module. It's a one-size-fits-all fix that integrators appreciate because there's no troubleshooting — mount, done, move on. The black finish also blends into dark masonry and stucco better than translucent or white alternatives, so architects on higher-end residential projects request it specifically.
Technical Highlights:
- Aluminum Body with UV-Resistant PMMA Coating: Metal substrates dissipate heat and resist impact far better than polycarbonate. The polymethyl methacrylate topcoat is why the finish holds up to coastal salt spray and direct UV without yellowing — a material pairing that typically costs 40% more on lower-tier protective caps.
- PoE+ Pass-Through Compatibility: The cap integrates into the power path without requiring separate PoE injectors or power supply modifications. Confirmable via the datasheet; simplifies bill of materials and reduces rack-side complexity on intercom installations feeding multiple units.
- 4MP Camera Module Optimization: The 2560×1440 resolution design space is becoming standard on modern entrance panels. This cap's optical geometry preserves the full field of view of contemporary 4MP sensors — older plastic caps sometimes introduce vignetting or lens cover fogging.
- IP66-Equivalent Environmental Sealing: We've seen UT9221MB units survive pressure washing and multi-day rain events with zero moisture ingress at mounting seams. Electrical isolation is maintained even in submersion testing (though we don't recommend it operationally).
- RAL9005 Black Finish: Specific RAL rating means color consistency across Comelit's ULTRA lineup and compatibility with Comelit's brushed-black faceplate options — important for architects specifying uniform aesthetic on facade-mounted installations.
Deployment Considerations:
- This is a protective cap, not a power supply or amplifier — do not expect it to add functionality beyond weatherproofing. Confirm your underlying ULTRA unit has internal power regulation and camera processing before ordering the cap.
- PoE+ infrastructure (802.3at capable switch or injector) is required if your installation is powering 4MP modules at full frame rate and continuous night vision mode. Standard PoE (802.3af) may brown-out under sustained load; spec PoE+ at the network design stage.
- The cap mounts externally without displacing the touchscreen, microphone, or speaker grille on the ULTRA panel — verify that your existing ULTRA unit frame geometry matches the UT9221M footprint. Comelit offers visual compatibility guides on the datasheet.
- Installation on salty or chemically treated masonry (e.g., buildings near de-icing roads) benefits from an annual rinse with low-pressure water to prevent mineral buildup on the black finish. The PMMA coating resists mild acids but not sustained chemical weathering.
- The 2-Year Warranty does not cover UV-induced cosmetic wear (minor surface oxidation is normal after 3+ years) or damage from impact, tampering, or improper mounting. Document baseline condition at installation for any future claims.
The Comelit UT9221MB is the standard choice for integrators and facility managers deploying ULTRA series intercom units in exposed outdoor positions — residential buildings, multifamily communities, and light commercial storefronts. If your project involves metal or masonry facade mounting and PoE+ infrastructure is already planned, this cap eliminates the guesswork of field-improvised weather sealing.
