Comelit 909020116 GS3-LF Vandal Resistant Proximity Reader
The Comelit 909020116 is a vandal-resistant proximity reader engineered for access control deployments in exposed, high-traffic environments—parking garage entrances, loading docks, exterior pedestrian gates, and perimeter security checkpoints. The stainless steel grade 304 enclosure and IK10-equivalent impact resistance withstand deliberate tampering and environmental stress that would compromise standard readers within months. PoE+ (802.3at) power delivery at 15.4W eliminates dedicated 24V power runs, consolidating cabling and reducing electrical infrastructure cost and installation labor. IP67 weather resistance ensures operation across temperature extremes and wet conditions without sealed cabinet ventilation complexity.
Key Features
- Vandal-Resistant Enclosure: Stainless steel grade 304 construction with ruggedized design. Rated for high-impact environments where standard readers fail within months; suitable for public-facing access points without protective bollards or cages.
- PoE+ Power Delivery: 802.3at (PoE+) 15.4W draw. Eliminates separate 24V transformer and conduit runs; single Cat6/Cat6a run powers and connects the reader to your access control network.
- IP67 Environmental Rating: Sealed for rain, dust, and hose-down cleaning. Maintains operation in outdoor and wet-environment deployments without environmental enclosure upgrades.
- Audible Sounder and Visual Indicators: Red/Green LED status lights and integrated audio feedback. Users receive immediate access-granted or denied indication without separate buzzer or chime hardware.
- Compact Footprint: 100×100×16 mm (3.94×3.94×0.63 in.) housing fits standard single-gang electrical boxes or surface-mount pedestals. Lightweight (0.442 kg) simplifies wall or pole installation without heavy-duty brackets.
- Proximity Card Protocol Compatibility: Integrates with networked access control platforms supporting standard proximity reader credential formats (125 kHz, 26-bit, 37-bit card encoding). Protocol verification required before deployment.
- 2-Year Manufacturer Warranty: Factory-backed coverage against defects in materials and workmanship under normal operational conditions.
Proximity readers rely on credential format alignment between the card stock (26-bit Wiegand, 37-bit, etc.) and the access control system's reader configuration. The 909020116 operates over standard Ethernet using PoE+ delivery, but the underlying proximity protocol must match your platform's input specification. Before speccing this reader, confirm your access control system's supported card formats and reader protocol documentation. Mismatched credentials result in failed access attempts that require field reprogramming or reader replacement.
Deployment scenarios span perimeter security (exterior pedestrian gates, vehicle entry lanes), high-traffic indoor access (lobby turnstiles, loading dock checkpoints), and multi-tenant or public-facing facilities where reader durability and weather resistance justify the vandal-resistant form factor. The stainless steel housing and sealed IP67 design handle parking structure freeze-thaw cycles, coastal salt spray, and industrial washdown environments that corrode standard aluminum readers. PoE+ power consolidation reduces installation time on new or retrofit projects; existing PoE+ infrastructure (campus networks, modern office buildings) requires no additional electrical work.
Network integration assumes your access control platform accepts proximity reader input via Ethernet or serial protocol gateway. Standalone proximity readers (non-networked, wired-relay output only) may require an intermediary controller or gateway to communicate with cloud-based or IP-native access management systems. Confirm your VMS or access control platform's reader protocol support; legacy systems may require a serial-to-Ethernet converter or reader-specific gateway module. Total cost of ownership includes the reader, PoE+ switch port allocation (verify 802.3at budget on your switch), and any protocol gateway hardware if your platform does not natively support the 909020116's credential format.
The Comelit 909020116 carries a 2-Year Manufacturer Warranty covering defects in materials and workmanship. For integrators deploying networked access control across Comelit-compatible platforms, the vandal-resistant form factor and IP67 rating justify selection in outdoor, high-impact, or weather-exposed locations where reader lifespan and serviceability are critical.

We've deployed the Comelit 909020116 across parking structures, outdoor loading docks, and multi-tenant facilities where reader durability and network-native power delivery matter as much as access control logic. The stainless steel enclosure and IP67 sealing eliminate the corrosion and moisture failure modes that plague standard aluminum readers in coastal or industrial washdown environments. On a 200-space parking structure retrofit, we've seen the vandal-resistant housing prevent repeat reader theft and tampering incidents that had plagued the facility's previous unarmored readers—a meaningful operational gain on sites where reader replacement labor and credential re-enrollment create administrative overhead. The PoE+ power model is the real labor saver: no separate 24V runs, no 120V-to-24V transformer cabinet, no conduit co-location conflicts with IT teams. A single Cat6 run does the job. That said, the 909020116 is not a credential management platform—it reads proximity cards and forwards the data to your access control system. If your platform doesn't natively support the credential format (125 kHz Wiegand, 26-bit, 37-bit), you'll need a protocol gateway or a reader that supports your card stock. We've had integrators spec this unit only to discover the customer's legacy controller doesn't recognize the credential format—a painful field discovery. Verify protocol compatibility in the RFQ stage. The IP67 rating and stainless steel construction make it overkill for indoor office lobbies with low foot traffic and climate control; for those, a standard plastic-housed reader on a PoE+ injector is cheaper and faster to deploy. But for perimeter security, outdoor high-traffic corridors, and environments where weather and impact are real concerns, the 909020116 delivers measurable durability and simplicity.
Technical Highlights:
- PoE+ 802.3at at 15.4W: Full-featured reader powered by standard PoE+ switch port—no transformer, no separate circuit. Verify your switch's per-port PoE+ budget (usually 30W per port on modern infrastructure); older equipment or heavily loaded switches may require port audit before deployment.
- Stainless Steel Grade 304 Enclosure: Resists corrosion in salt spray, industrial washdown, and freeze-thaw environments. Standard aluminum readers degrade within 2–3 years in coastal or wet-industrial settings; 304 stainless extends service life to 7+ years with minimal maintenance.
- IP67 Environmental Sealing: Sealed against dust and direct water spray—suitable for outdoor mounting without weather-protection cabinets or secondary enclosures. Eliminates capex and installation complexity on exterior gate and perimeter deployments.
- Integrated Audible/Visual Feedback: Red/Green LED status and sounder eliminate separate buzzer or external chime hardware. Users receive immediate granted/denied feedback; reduces help desk calls from confused cardholders in outdoor or noisy environments.
- Proximity Card Protocol: Reads standard 125 kHz proximity cards (26-bit, 37-bit Wiegand formats). Protocol must match your access control platform's input specification—no plug-and-play protocol negotiation. Card format mismatch results in failed reads and requires field reconfiguration.
Deployment Considerations:
- Verify PoE+ switch port availability and per-port budget before deployment. Most modern enterprise switches support 802.3at, but campus networks with mixed-generation switching may have legacy 802.3af-only ports—confirm before ordering network infrastructure.
- Credential format verification is non-negotiable. Proximity readers do not auto-negotiate card encoding; if your access control system expects 37-bit credentials and the reader outputs 26-bit Wiegand, the system will reject all cards. Obtain platform documentation and reader compatibility matrix before finalizing the RFQ.
- Stainless steel housing and sealed design add weight and thermal mass compared to plastic readers—wall mounting requires appropriate anchors. Pedestal mounting (bollard-style) is common for exterior pedestrian gates; confirm mounting hardware availability and labor cost in your site survey.
- IP67 sealing is one-way—the reader is sealed, but the network cable entry point is not. Use Cat6 couplers or weatherproof RJ45 connectors if the cable run is exposed to direct spray or standing water. PoE+ injectors or PoE+ switch ports must be indoors or in weatherproof cabinets.
- No built-in wireless connectivity; this is a wired-Ethernet-only reader. Sites requiring mobile credential support or cloud-native access control will need a separate mobile reader or a networked platform that aggregates the 909020116 with mobile card readers.
The Comelit 909020116 is the right choice for outdoor, high-traffic, or high-impact access control installations where reader durability and network simplicity (PoE+ power) are non-negotiable. Indoor office environments, climate-controlled lobbies, and low-traffic corridors should consider standard plastic-housed readers to reduce capex.
