HID 40NKS-00-000000 vs Comelit 909020113: Specification Comparison
Both the HID 40NKS-00-000000 SIGNO 40 and the Comelit 909020113 GS3-MT are wired, wall-mount proximity card readers designed for access control deployments. Each supports Wiegand output and targets installers integrating readers into panel-based or IP-based access systems. The comparison centers on credential technology, power delivery, environmental rating, and panel compatibility — the three axes that most directly determine fit in a retrofit or new-build project.

Which reader supports the credential types and protocol output your access panel requires?
The HID 40NKS-00-000000 outputs 32-bit Wiegand MSB and is specified for EM 32-bit proximity credentials conforming to ISO/IEC 11784/11785. The spec sheet also notes NFC/BLE, SEOS, Smart, and Standard profile support, though those entries appear in an incomplete spec field and cannot be confirmed as fully supported on this exact SKU without the datasheet. The Wiegand output itself is unambiguous: Data0, Data1, Common.
The Comelit 909020113 supports PAC OPS™ and KeyPAC proprietary credentials in addition to third-party Wiegand credentials, making it a multi-technology reader on a single hardware platform. Its Wiegand protocol compatibility is confirmed, but the specific bit-format (e.g., 26-bit vs. 32-bit) is not stated in the provided specs. Enhanced encryption certification is noted only when used in conjunction with PAC 512 controllers — it is not an unconditional feature.
Buyers locked to EM 32-bit legacy card stock will find the HID unit's ISO/IEC 11784/11785 compliance directly stated. Buyers running PAC OPS™ or KeyPAC credentials gain native support only from the Comelit unit. Both devices output Wiegand, but HID explicitly documents the 32-bit MSB format; Comelit's bit-width is not specified.
How does each reader handle power delivery and environmental exposure?
The HID 40NKS-00-000000 accepts either PoE or 12VDC, giving installers flexibility to power from a panel power supply or an 802.3af PoE switch without adding a mid-span injector. No IP rating is stated in the provided specs, though the product is noted as rated for indoor/outdoor use. No weight or housing material is documented in the provided data.
The Comelit 909020113 is powered exclusively via PoE (802.3af, 13W minimum per port). No 12VDC option is stated. The housing is UL-rated polycarbonate with a confirmed IP65 rating, making it formally weatherproof against dust ingress and low-pressure water jets. Dimensions are 89 × 115 × 28 mm and weight is 0.290 kg / 0.639 lb.
For sites where existing panel wiring carries 12VDC, the HID reader's dual-power option avoids infrastructure changes. For new IP-cabling runs where a PoE switch is already present, the Comelit's single-cable PoE solution simplifies installation. The Comelit's IP65 rating is a documented, verifiable specification; the HID's outdoor suitability is noted but no IP ingress rating is provided in the supplied data.
What integration, tamper, and controller-compatibility features differentiate the two readers?
The HID 40NKS-00-000000 provides LED (green for valid read, red for status) and buzzer feedback. Mounting options include surface-mount wall installation with flush-mount terminal block and pigtail wiring. No tamper circuit is documented in the provided specs. Compatibility is described as supporting 'legacy and modern access panels' via standard Wiegand.
The Comelit 909020113 includes an integral tamper circuit and mounting plate. The tamper line function becomes configurable when paired with PAC 512 controllers — a platform-specific enhancement, not a universal feature. Audio (sounder) and red/green LED indicators are confirmed. The package contents description notes the reader is installation-friendly for mixed-technology environments.
The Comelit unit's built-in tamper circuit is a meaningful differentiator for installations requiring supervised reader lines — common in higher-security or insurance-mandated deployments. HID's pigtail and terminal block flexibility supports more varied physical mounting scenarios. Neither reader documents remote firmware update capability or OSDP in the provided specifications.
Which should you choose: the 40NKS-00-000000 or the 909020113?
Our take: The 40NKS-00-000000 is the stronger choice when the site uses EM 32-bit legacy card stock, requires 12VDC power from an existing panel supply, or must integrate with a broad range of access panels via documented 32-bit Wiegand MSB output. The 909020113 is the stronger choice when the deployment runs PAC OPS™ or KeyPAC credentials, uses PoE infrastructure for single-cable runs, or requires a confirmed IP65 weatherproof rating and an integral tamper circuit — three features not documented for the HID unit in the provided specs. Concretely: HID supports dual power (PoE or 12VDC) versus Comelit's PoE-only; Comelit carries a stated IP65 rating versus no IP rating stated for HID; and Comelit includes a built-in tamper circuit versus none documented for HID. Specify the Comelit for PAC 512-based systems or supervised tamper requirements; specify the HID for legacy EM-card retrofits with panel-side 12VDC power.

Frequently Asked Questions
Which should you choose: the 40NKS-00-000000 or the 909020113?
The 40NKS-00-000000 is the stronger choice when the site uses EM 32-bit legacy card stock, requires 12VDC power from an existing panel supply, or must integrate with a broad range of access panels via documented 32-bit Wiegand MSB output. The 909020113 is the stronger choice when the deployment runs PAC OPS™ or KeyPAC credentials, uses PoE infrastructure for single-cable runs, or requires a confirmed IP65 weatherproof rating and an integral tamper circuit — three features not documented for the HID unit in the provided specs. Concretely: HID supports dual power (PoE or 12VDC) versus Comelit's PoE-only; Comelit carries a stated IP65 rating versus no IP rating stated for HID; and Comelit includes a built-in tamper circuit versus none documented for HID. Specify the Comelit for PAC 512-based systems or supervised tamper requirements; specify the HID for legacy EM-card retrofits with panel-side 12VDC power.
Is the HID 40NKS-00-000000 or the Comelit 909020113 better for outdoor installations?
The Comelit 909020113 has a confirmed IP65 rating in the provided specifications, meaning it is formally rated as dust-tight and resistant to low-pressure water jets. The HID 40NKS-00-000000 is described as suitable for indoor/outdoor use, but no IP ingress protection rating is stated in the supplied data. If a verified weatherproof rating is a project requirement, the Comelit's IP65 is the documented choice; HID's outdoor suitability cannot be confirmed to an equivalent standard from the specs provided.
Can either reader work with my existing 12VDC panel power supply?
Yes — but only the HID 40NKS-00-000000. Its specifications list both PoE and 12VDC as accepted power inputs, so it can be wired directly to a panel's auxiliary power output without a PoE switch or injector. The Comelit 909020113 specifies PoE (802.3af) as its power source, with a noted minimum of 13W per port; no 12VDC input option is documented in the provided specs.
Which reader is better suited for a PAC-based access control system?
The Comelit 909020113 is purpose-built for PAC ecosystems. It natively supports PAC OPS™ and KeyPAC credentials and gains a configurable tamper line function when paired with PAC 512 controllers. The HID 40NKS-00-000000 outputs standard 32-bit Wiegand MSB, which many panels — including some PAC controllers — can accept, but it does not offer native PAC credential support or PAC-specific feature activation. For a PAC 512 deployment requiring tamper supervision and proprietary credential handling, the Comelit unit is the specified fit.
