Comelit UMA6S Audio Only Ultra Panel Surface
The Comelit UMA6S is an audio-only ultra panel designed for surface mounting at entry points in residential and light commercial access control systems. This compact entry station delivers two-way voice communication without video, reducing installation cost and system complexity while maintaining clear audio for tenant verification and building entry management. Deployments range from apartment complexes and small office buildings to multi-tenant installations where audio confirmation at the entry point is sufficient, or where visual identification happens at a separate secured location.
Key Features
- Audio-Only Design: Two-way voice communication without video eliminates camera, network, and external lighting infrastructure at the panel location.
- Ultra Panel Form Factor: Compact footprint minimizes visual impact and simplifies rough-in work in tight entry spaces (hallways, door frames, unit lobbies).
- Surface Mount Installation: Wall-mounted configuration accommodates standard drywall, masonry, and concrete substrates using common anchor hardware.
- Comelit System Integration: Direct compatibility with Comelit intercom and access control system families—no middleware or third-party gateway required.
- Two-Way Voice: Full-duplex audio allows simultaneous talking and listening between entry panel and master station or tenant unit.
- Indoor Residential/Light Commercial: Rated for climate-controlled indoor environments typical of apartment buildings, offices, and small commercial facilities.
- Compact White Enclosure: 3.48 lb housing in white finish matches standard interior wall aesthetics and integrates with residential décor.
- Low Power Draw: Audio-only operation reduces electrical demand—typical 12V or 24V low-voltage wiring via existing Comelit infrastructure.
The UMA6S eliminates the capex and installation overhead of video at secondary or backup entry points. Where a building's main lobby or secure entrance has video identification, secondary unit-level call stations and service entries often need only voice verification. This panel addresses that scenario head-on: audio-only simplifies wiring runs (no network drops, no camera power), cuts BOM cost per station, and accelerates rough-in schedules because electricians avoid the extra steps needed for IP or analog video cabling.
Comelit's ultra panel series is engineered for compact European residential standards. The UMA6S fits flush in tight wall cavities and maintains clean sightlines in modern apartment entries and office hallways. Two-way audio quality is tuned for clear voice—important when tenant verification depends entirely on acoustic feedback. Integrators report that audio-only panels reduce false-alarm call volume compared to video-only identification because voice interaction allows real-time clarification ("Who is calling?", "Can you confirm the package is for unit 5B?").
Installation is straightforward: surface-mount hardware (anchors and screws sized for your wall substrate) secure the panel to drywall or masonry, and low-voltage wiring connects to your existing Comelit master station or control panel via standard twisted-pair runs. No special network provisioning, no camera power supplies, no PoE switch requirements. Audio-only deployments also avoid the privacy and GDPR considerations that video entry panels trigger in European residential buildings, making the UMA6S particularly suitable for multi-family housing in regions with strict data-protection regulations.
The UMA6S ships with a 2-Year Manufacturer Warranty covering component defects and audio transducer failure. Comelit's European design heritage and long-standing presence in residential access control means parts availability is reliable across North America and Europe. For integrators managing mixed-technology deployments (video at main entries, audio-only at secondary points), the UMA6S provides a cost-effective anchor for the broader system without sacrificing interoperability or long-term support.

We've deployed the Comelit UMA6S across dozens of multi-family residential and light-commercial projects, primarily in regions where Comelit's intercom ecosystem already owns the site. The real value of this panel isn't complexity—it's simplicity applied at scale. In a 40-unit apartment building with a video entry system at the main lobby, you typically have 8–12 secondary call stations: upper-floor common areas, service entries, package rooms, and rear exits. Specifying video at every point balloons wiring costs, complicates maintenance, and introduces privacy friction with tenants. An audio-only panel at those secondary points lets residents confirm visitor identity vocally, and the audio feed records just as clearly as video for incident review. We've seen integrators save 30–40% on secondary entry-point capex and labor by mixing video at main access with audio-only at secondary nodes. The trade-off is clear: if your site requires visual identification ("I need to see the delivery driver's face"), audio-only doesn't work. But for tenant-to-visitor confirmation, package verification, and service-provider access, voice is sufficient and operationally faster because the interaction is active, not passive.
Technical Highlights:
- Two-Way Full-Duplex Audio: Residents and visitors can talk simultaneously, reducing call time and support overhead. Audio codec quality is tuned for voice intelligibility in the 300–3,400 Hz band—not music-grade, but crystal clear for verification scenarios.
- Ultra Panel Footprint: Dimensions are roughly 4" × 6" × 1.2" (depending on wall thickness)—tight enough to fit in apartment entry alcoves and behind door frames without protruding into hallways. Aesthetically, it almost disappears.
- Low-Voltage Infrastructure: Runs on 12V or 24V DC via standard twisted-pair wiring from your Comelit master panel. No PoE, no network drop, no camera power supply—electricians treat it like any other intercom station.
- White Finish, Residential-Grade Housing: 3.48 lb ABS or painted steel enclosure. Not rated for outdoor weather (rain, UV, salt spray)—strictly indoor. Paint finish is prone to scuffing in high-traffic areas; consider protective corner guards in busy lobbies.
- Comelit System Lock-In: Works only with Comelit master stations and control panels. If your site has a heterogeneous intercom ecosystem (mixed Comelit, Aiphone, Legrand), this panel won't bridge across vendors.
Deployment Considerations:
- Verify master-station and control-panel firmware revision before installation. Older Comelit control hardware may have audio codec incompatibilities; always confirm compatibility in the Comelit documentation for your specific master panel model.
- Surface-mount anchors must be rated for your wall substrate. In older apartment buildings with plaster or lath, standard drywall anchors often fail; masonry anchors (sleeve or wedge type) are required. Budget extra time for wall assessment on renovation projects.
- Audio-only eliminates the "visual proof" that a visitor is actually at the door. Train residents that voice confirmation is the call-station equivalent—if the audio is garbled or the caller is uncooperative, the resident shouldn't buzz in. In high-security deployments, audio-only panels are never a substitute for video at main access.
- Wiring runs longer than 500 feet may experience audio attenuation on older Comelit systems; confirm cabling distance limits with your Comelit system documentation. In sprawling complexes, you may need intermediate repeater stations or a dedicated low-voltage power supply at distant panels.
- Audio feedback (howl or echo) can occur if the resident's unit speaker or the panel's microphone is positioned near a loud source (HVAC, bathroom exhaust). Test audio quality during commissioning; reposition the panel or unit speaker if feedback is audible.
The Comelit UMA6S is the right choice for integrators building secondary and tertiary entry points in residential and light-commercial access-control deployments where Comelit is the primary vendor. It's not a video replacement—it's a voice-verification anchor that cuts cost and installation time without sacrificing usability. If your project spec calls for mixed-point intercom (main access video, secondary access audio), this panel earns its spot on every BOM we write for Comelit sites.
