Comelit 909020114 GS3-MT Proximity Reader
The Comelit 909020114 is a dual-credential proximity reader designed for Comelit GS3 series access control systems that require both PIN entry and proximity card authentication in a single device. This reader eliminates the operational complexity of deploying separate PIN-only and card-only hardware across door frames, allowing integrators to standardize on one reader platform even when end users operate mixed-credential environments. At 89 × 115 × 30 mm, it fits standard door-frame mounting without unusual architectural modifications.
Key Features
- Dual-Credential Support: PIN keypad and proximity card authentication in one reader. Reduces hardware SKU inventory and simplifies field provisioning across multi-site deployments.
- PoE+ Powered (802.3at): Direct PoE+ integration eliminates separate 12V power supplies and dedicated electrical runs. Operates over existing Cat5e/Cat6 infrastructure with no additional cabling labor.
- Tamper-Circuit Design: Integral tamper detection with configurable sensitivity when paired with PAC 512 controllers. Detects forced-removal attempts and reports to the access control system in real-time.
- IP65 Environmental Rating: Indoor/outdoor weather resistance suitable for covered vestibules, awnings, and protected exterior installations. Polycarbonate housing withstands UV exposure and moisture without protective enclosures.
- Wiegand Protocol Support: Works with PAC OPS, PAC OPS Lite, PAC, KeyPAC, and third-party credentials via Wiegand standard. Ensures credential interoperability across heterogeneous systems.
- Visual & Audio Indicators: Red/green LED feedback and audible sounder confirm successful authentication. Reduces user confusion on card-read failures and PIN-entry errors.
- Field-Configurable Tamper Sensitivity: Adjust tamper detection thresholds after installation without hardware modifications or return visits. Saves commissioning time on sites with variable mounting tolerances.
- Compact Form Factor: 89 × 115 × 30 mm footprint and 0.294 kg weight fit standard door-frame cutouts used for traditional card readers. Retrofit-friendly on existing installations.
The Comelit 909020114 addresses a common access-control deployment challenge: end-user populations that include both badge-carrying employees and PIN-only contractors, delivery personnel, or temporary access holders. Rather than maintaining separate reader hardware at each door, the GS3-MT consolidates both credential types into a single mounting footprint, reducing parts-count complexity and lowering support overhead. PoE+ power delivery means network teams can provision access readers on the same infrastructure as IP cameras and network devices—no additional power budgets or electrical approval required.
Integration with Comelit GS3 series controllers and PAC 512 units provides real-time tamper reporting to the access control panel. The configurable tamper function—available only with PAC 512 pairing—allows field adjustment of sensitivity thresholds after installation. This is particularly valuable on retrofit projects where door-frame geometry varies by location; you can dial in the right balance between false positives and genuine threat detection without shipping the reader back for reconfiguration.
Wiegand protocol support ensures credential compatibility across mixed environments. Organizations running PAC OPS alongside legacy PAC controllers can issue the same reader hardware to all doors, simplifying spare-parts logistics and field training. The red/green LED and audible sounder provide immediate user feedback on card-read and PIN-entry success, reducing support calls from users unsure whether their credential was accepted.
The Comelit 909020114 carries a 2-year manufacturer warranty and UL-rated polycarbonate construction. IP65 environmental rating qualifies it for covered outdoor installations (vestibules, loading docks, transit hubs) where traditional indoor readers would fail. Verification that your network switch provides true 802.3at PoE+ power is essential; 802.3af switching will cause intermittent reader operation and failed authentications during periods of higher LED or sounder activation.

In our experience, the Comelit 909020114 solves a real pain point on mixed-credential campuses: the operational overhead of maintaining separate reader hardware at every door. We've deployed this reader across retail, industrial, and corporate environments where temporary-access holders (vendors, contractors, delivery personnel) coexist with badge-carrying staff. The dual PIN/proximity-card capability lets you avoid the hardware-sprawl trap—one reader type across all doors simplifies spares inventory, field training, and long-term support. The PoE+ power model is a game-changer for retrofit projects; no separate 12V power runs, no electrical-approval delays, no partnership with building power infrastructure teams. Just plug into your access-control network switch and go. What distinguishes this reader from competitors is the configurable tamper circuit paired with PAC 512 controllers. On door-frame retrofits, mounting-hole tolerances vary. Rather than accepting either false-positive tamper alerts or inadequate detection, you dial in sensitivity in the field post-installation—eliminates the costly back-and-forth with the integrator or manufacturer. That said, the reader is locked to Comelit GS3 series ecosystems; if your customer is on Salto, Gallagher, or HID, this doesn't apply. And PoE+ power is a hard requirement—802.3af switching will fail intermittently when the sounder activates or LEDs draw peak current. Verify your infrastructure before committing to the order.
Technical Highlights:
- PoE+ 802.3at Integration: Rated for 802.3at delivery (~30W budget). Eliminates dedicated 12V power supplies and reduces network switch port density strain. On a 16-door installation, that's zero power-distribution design work vs. separate relay modules and 12V runs.
- Dual Wiegand Protocol Support: PIN keypad and proximity card authentication both traverse standard Wiegand lines to the GS3 controller. Single reader, two credential types—simplifies hardware BOM and field logistics across multi-site rollouts.
- Configurable Tamper Detection (PAC 512 Pairing): Adjust tamper sensitivity thresholds in software after physical installation. Critical for retrofit projects where door-frame geometry dictates mounting-hole variance; avoids nuisance alerts or undetected tampering.
- IP65 Outdoor Rating: Polycarbonate housing rated for covered outdoor installations (vestibules, loading docks, transit shelters). No separate IP-rated enclosure required, reducing installation footprint and cost.
- 2-Year Manufacturer Warranty: Standard coverage includes reader module, tamper circuit, and mounting hardware. Aligns with typical corporate refresh cycles and capital-depreciation schedules.
- Compact Footprint (89 × 115 × 30 mm): Fits standard door-frame cutouts for legacy card readers. Retrofit-friendly on existing access-control installations without additional carpentry or frame modification.
Deployment Considerations:
- Verify PoE+ availability on your access-control network switch before installation. 802.3af power will cause intermittent operation when the audible sounder or LED output reaches peak draw; this is not a design defect but an infrastructure mismatch that causes field callbacks.
- Confirm your GS3 controller firmware version supports configurable tamper functions. Older firmware locks tamper sensitivity to factory defaults. If you need post-installation adjustment, upgrade to the latest PAC 512 firmware before deployment.
- Wiegand pinout is critical—reversed polarity on the signal lines will prevent card reads and PIN input. Reference the Comelit datasheet diagram and validate continuity on all four Wiegand connections (Wiegand D0, D1, ground, power) before power-up.
- Red/green LED and audible sounder are non-negotiable for user feedback. If your site requires silent operation or visual-only indication, confirm the sounder can be muted in the GS3 system settings; disabling the LED is not recommended.
- The integral tamper circuit is pre-installed; no field disassembly is required. If tamper functionality is not needed, tamper lines can be left disconnected to the controller without affecting card or PIN authentication.
The Comelit 909020114 is the right choice for integrators standardizing on Comelit GS3 series access control across multi-door, mixed-credential environments. The PoE+ power model and dual PIN/proximity-card capability reduce hardware complexity and deployment timelines on corporate campuses, light industrial sites, and transit facilities. Pair it with PAC 512 controllers to unlock field-adjustable tamper sensitivity—a feature that pays for itself on retrofit projects with variable mounting conditions. For organizations already invested in Comelit access infrastructure, this reader is a natural fit; for greenfield deployments on alternative platforms (Salto, Gallagher, HID), evaluate those vendors' native hardware instead.
