Comelit UT9230MB Metal Ultra Blank Module Black
Overview
The Comelit UT9230MB is a metal blank module engineered for the Comelit Ultra series entrance panel systems. This accessory fills unused module positions in multi-unit door entry installations, presenting a finished, professional appearance without requiring active connections. Constructed from anodised aluminium alloy with a black RAL9005 finish, the UT9230MB maintains visual consistency across your intercom lineup while preserving the option to add functionality later during system expansion or reconfiguration.
Key Features
- Full Metal Construction: Anodised aluminium alloy housing resists corrosion and oxidation in residential and light commercial environments — no plastic trim, which matters if your panel sees weather exposure or heavy foot traffic in covered lobbies.
- Compact Dimensions (100 × 90 × 35 mm): Fits seamlessly into the modular slot pattern of Comelit Ultra panels without gaps or protrusions that would disrupt the visual line. Precise depth ensures flush mounting alongside active modules.
- Black RAL9005 Finish: Standard industrial black matches Comelit's design language across the Ultra series. Anodising provides UV and scratch resistance compared to paint alone — relevant if your entrance vestibule has direct sunlight or high contact.
- PoE Integration: Operates within PoE+ (802.3at) powered system infrastructure when installed in compatible Comelit Ultra configurations. No separate power supply needed — your existing switch powers the entire panel assembly.
- Tool-Free Module Swap: Designed for quick insertion and removal into the Ultra panel's modular framework, allowing you to upgrade or reconfigure without rewiring or panel downtime.
- Aesthetic Placeholder: Eliminates the visual clutter of empty slots on multi-unit panels. In a 4-unit or 6-unit installation where one unit is not yet active, the blank module presents a complete, intentional appearance rather than a visibly incomplete installation.
Integration & Compatibility
The UT9230MB integrates exclusively with Comelit Ultra series door entry systems that use the modular framework design. It is not compatible with legacy Comelit systems or third-party intercom platforms. When used as part of a complete Ultra panel assembly, the UT9230MB operates passively — it requires no configuration, no network address, and no VMS binding. It simply occupies a physical slot, leaving that position reserved for future module installation or keeping the panel frame visually complete.
Deployment scenarios include: residential multi-unit buildings where some units do not yet require video or audio entry stations; commercial reception areas undergoing phased expansion; and rental properties where tenant configurations change seasonally. The blank module is most effective when your panel layout is established but your module configuration is not yet final.
What's in the Box
The package contains one UT9230MB blank module ready for immediate installation into a compatible Comelit Ultra panel frame.
Frequently Asked Questions
Q: Can I install the UT9230MB in a non-Comelit panel?
A: No. The UT9230MB is designed exclusively for Comelit Ultra series panels with the matching modular slot framework. It will not fit third-party entrance systems.
Q: Does the UT9230MB require any network or power configuration?
A: No configuration is needed. The UT9230MB is a passive placeholder — it draws no individual power and carries no network address. It operates passively within the PoE+ powered panel infrastructure.
Q: Can I replace a blank module with an active module later without removing the entire panel?
A: Yes. The modular design allows you to remove and swap the UT9230MB for an active module (such as a video or audio station) without disassembling the panel frame, provided the panel remains powered down during the swap.
Q: What finish is the UT9230MB, and will it match my existing Ultra modules?
A: The UT9230MB is finished in black RAL9005 with anodised aluminium coating, the standard finish for Comelit Ultra series modules. It will match black variants of other Ultra modules visually.
Q: What are the exact dimensions of the UT9230MB?
A: The module measures 100 mm (L) × 90 mm (H) × 35 mm (D), designed to fit the standard Ultra panel slot spacing without interference.
The Comelit UT9230MB is a straightforward piece — a metal placeholder module for the Comelit Ultra entrance panel series. If you're specifying a multi-unit intercom installation where not all units are live yet, or where you want to reserve a slot for future expansion without leaving an ugly empty frame, this is the module that does it. The anodised aluminium (RAL9005 black) finish means you're not fighting corrosion or paint peeling in a lobby environment.
Technical Highlights:
- Anodised Aluminium Alloy Construction: The anodising process creates a corrosion-resistant oxide layer on the aluminium — this matters in humid or salt-air environments where bare metal or painted finishes degrade. Your blank module stays visually consistent for years without oxidation bloom.
- Precise Dimensions (100 × 90 × 35 mm): The 35 mm depth is critical — it ensures the blank module sits flush with active modules in the panel frame. A module that sits proud or recessed breaks the visual line and screams 'incomplete installation' to tenants and visitors.
- PoE+ System Integration: The module draws no individual power and carries no network load — it's purely mechanical. But it lives in a PoE+ powered panel ecosystem, so your power budget planning is simplified; you count only active modules, not blanks.
Deployment Considerations:
- The UT9230MB is passive and Comelit-exclusive — it will not retrofit into other panel systems. Verify your panel is Comelit Ultra before ordering.
- If your building code or fire authority requires all intercom positions to be 'finished' (rather than visibly vacant), this module solves that compliance concern without activating unnecessary hardware.
Best fit: residential multi-unit buildings with phased tenant turnover, or commercial properties where module requirements shift seasonally. Buy it when your panel frame is set but your module mix is not.
