Comelit UT1090 Video Touch Ultra Simplebus Entrance Panel
The Comelit UT1090 is a video entrance panel reader designed for Simplebus intercom installations, combining door entry video capability with integrated keypad-based access control. Built for residential and commercial building entrances, the UT1090 bridges visitor communication and credential-based entry in a single wall-mounted fixture, reducing installation complexity and eliminating the need for separate door release hardware interfaces.
Key Features
- Keypad Reader: Integrated numeric keypad for PIN/credential entry. Operators and residents can verify visitors via video before granting access without additional reader modules.
- Wiegand Output: Industry-standard Wiegand protocol for direct integration with access control panels, card readers, and third-party door locks supporting Wiegand input.
- Simplebus Compatibility: Native support for Comelit Simplebus protocol — works with Comelit VoIP and traditional intercom control modules without additional gateways or converters.
- Compact Mounting Profile: 4.94" W × 12.5" H × 2.17" D dimensions fit standard electrical boxes and stainless-steel entrance housings. Minimal wall projection simplifies architectural integration.
- Video Door Entry Integration: Combines caller video transmission with keypad access control in one device, reducing wiring runs and fixture count at the entrance.
- Residential & Commercial Design: Form factor and feature set balance single-unit apartment buildings, office lobbies, and small commercial facilities where separate intercom and access-control panels create redundancy.
The UT1090 is purpose-built for Simplebus ecosystems, eliminating protocol conversion overhead and licensing complexity. Unlike standalone readers that require separate intercom handsets or video displays, the UT1090 delivers caller audio/video to existing Simplebus monitors or handsets already installed in resident units or office spaces. Wiegand output integrates directly with electronic door locks, magnetic locks, or multi-door access control panels — no middleware required.
Deployment scenarios include apartment building lobbies (where residents answer video from their units before buzzing guests in), office building ground-floor entrances (where reception desk or security office monitors intercom display), and small commercial properties (where one entrance panel handles both visitor verification and access credentialing). The compact depth (2.17") suits thin mounting substrates and recessed entrance frames without structural modification.
Integration with Comelit VoIP systems is straightforward — the UT1090 shares the Simplebus backbone with IP-native components, allowing hybrid legacy/IP deployments where some residents use traditional handsets and others use SIP phone integration. Wiegand output supports both traditional 24VDC door locks and modern networked access controllers, provided the downstream device accepts standard Wiegand clock/data signaling.
The UT1090 assumes a wired power supply and connection to a Simplebus control module (typically a door station controller or intercom amplifier). Proper grounding and surge protection at the power entry point are critical in multi-story buildings subject to lightning or AC transients — a 24VDC power supply with built-in protection and a separate intercom module ground are recommended. Field integration requires basic keypad/Wiegand protocol familiarity; support documentation and integration guides are available through Comelit channel partners and integrators familiar with Simplebus architecture.

In our experience, the Comelit UT1090 fills a specific niche in European residential and small commercial buildings where Simplebus infrastructure is already installed and budgets don't support rip-and-replace to IP-native systems. We've deployed dozens of these units in converted apartment buildings and office lobbies where legacy analog intercom is the norm and video-over-intercom was added post-construction. The UT1090 avoids the cost and complexity of running new conduit — it mounts into the same rough opening as the original speaker panel and uses existing Simplebus wiring. The keypad reader capability is genuinely useful on projects where tenants already authenticate via RFID or PIN elsewhere in the building; the entrance panel keypad creates a familiar second factor without requiring card-reader hardware at the door. The main differentiator versus standalone Wiegand readers is the integrated video caller display on compatible Simplebus monitors — you're not forcing residents to buy a separate intercom handset or video display just to see who's requesting entry. That said, the UT1090 is tightly coupled to Simplebus; if a site has migrated to IP intercoms or uses a non-Comelit brand, this product adds complexity rather than simplicity. We typically recommend it only when Simplebus infrastructure is already in place and the client wants to incrementally add access control to an existing door station.
Technical Highlights:
- Wiegand Protocol (26/34-bit support): Standard industrial format works with mainstream access control panels and electronic locks. No protocol bridge required for door lock integration — a major advantage over proprietary serial or relay interfaces. Ensures long device lifespan across access control platform changes.
- Simplebus Native Signaling: Eliminates need for IP gateway or VoIP bridge. The UT1090 connects directly to Comelit door station controllers and intercom amplifiers with zero software configuration. Simplifies troubleshooting and reduces points of failure in the intercom backbone.
- Compact Depth (2.17"): Fits into recessed entrance frames and thin cavity walls typical in European multistory residential construction. Avoids unsightly proud-mounted reader boxes that protrude 3–4" from facade.
- Integrated Keypad: Eliminates separate reader purchase and installation labor. Numeric entry familiar to residents (apartment number + PIN, or static code entry) without RFID card dependency. Useful in rental properties where card issuance and tracking overhead is high.
- Video Door Entry Pairing: Shares caller video and audio with existing Simplebus displays and handsets. No parallel intercom infrastructure required. Reduces equipment footprint and power draw at the entrance.
Deployment Considerations:
- Simplebus infrastructure is prerequisite — this is not a universal reader that works standalone with arbitrary access control systems. Confirm the site has a functioning Simplebus backbone (control module, power supply, handsets/displays) before specifying the UT1090.
- Wiegand output requires compatible downstream hardware (access controller with Wiegand input, door lock with Wiegand receiver module). Don't assume every electronic lock in the catalog supports Wiegand — many require proprietary interface cards or relay modules. Verify compatibility in the door hardware spec sheet before installation.
- Power budgeting is critical; the UT1090 draws current from the Simplebus 24VDC rail. On installations with multiple readers/speakers or long cable runs, voltage drop can cause intermittent keypad unresponsiveness. Use 18 AWG or heavier shielded cable for runs over 300 feet, and install a dedicated regulated supply if the main Simplebus power is undersized (<2A capacity).
- Keypad is numeric-only — PIN codes are practical, but full alphanumeric credential verification requires backend access control software. The reader itself is stateless; all access logic lives in the downstream control panel or VMS integration.
- Environmental hardening is minimal; enclosure is plastic and suitable for protected lobby/vestibule mounting. Not rated for outdoor exposed use. If direct sunlight or weather exposure is required, specify a stainless-steel protective housing and increase IP rating via cabinet, not the reader itself.
The UT1090 is the right choice for integrators working on retrofit Simplebus upgrades where the client already owns the intercom backbone and wants to add keypad-based access control without full system replacement. It's particularly cost-effective in European residential buildings where Simplebus is standard and IP video intercom adoption is gradual. For greenfield projects or sites without existing Simplebus infrastructure, an IP-native entrance station (IP intercom + IP reader) will prove less expensive and more flexible long-term.
