Altronix TV2 Access & Power Integration Door Backplane
The Altronix TV2 is an access and power integration door backplane designed to consolidate credential readers, power distribution, and access control electronics within a single integrated assembly. By eliminating multiple separate components at the door opening, the TV2 reduces field wiring complexity and installation labor—a material cost saving on large deployments. This backplane is built for standard access control system architectures, making it a drop-in fit for new construction and retrofit projects where space efficiency and maintainability matter.
Key Features
- Integrated Credential & Power Distribution: Single backplane assembly consolidates reader connectivity and power provisioning in one housing. Eliminates the need to route separate credential and power cables from the control panel to each reader.
- Reduced Field Wiring: Pre-integrated layout cuts door-opening installation time by bundling reader interfaces and power feeds. Labor savings scale across multi-reader installations and retrofit projects.
- Modular Reader Compatibility: Supports standard credential reader form factors (card, biometric, keypad). Flexible backplane design adapts to mixed-reader configurations without redesign.
- Standard Access Control Integration: Works with common access control panel architectures. No proprietary middleware or custom cabling required.
- Compact Door Frame Footprint: 20.7 x 1.3 x 26.4 in form factor fits standard door frame dimensions without frame reinforcement.
- Lifetime Limited Warranty: Factory-backed coverage reflects Altronix build quality and durability in commercial deployments.
- Power Centralization at Door: Integrates power distribution directly at the access point, reducing voltage drop and simplifying downstream branch circuits from the main panel.
- Maintenance Access: Backplane design places all reader connections and power feeds in one accessible location, lowering mean-time-to-repair for reader or wiring faults.
The TV2 is particularly valuable on multi-reader door openings—entrance vestibules, secure corridors, and checkpoint controls—where two or three readers (card + PIN pad + emergency keyswitch) are mounted side by side. Without a consolidated backplane, integrators route separate credential and power cables for each reader, creating cable congestion inside the door frame and multiplying termination points in the control panel. The TV2 consolidates those feeds into a single pre-wired assembly, cutting installation time and reducing the risk of field wiring errors.
Installation efficiency translates directly to project economics. On a 30-door office retrofit with dual-reader control, the labor savings from eliminating individual reader cable runs, panel routing, and termination can amount to 8–12 hours of field time. Scaled across larger campus or multi-site deployments, that footprint advantage compounds. The TV2 also simplifies future reader upgrades—swapping a worn card reader or adding a new biometric sensor requires only the credential reader module change, not wholesale recabling of power and panel circuits.
The backplane integrates seamlessly with standard access control architectures—Salto, Honeywell, Johnson Controls, Lenel, Genetec—because it acts as a passive power and signal distribution hub, not an intelligent control element. This architecture independence means specifying one backplane design across heterogeneous sites without SKU proliferation or integration testing overhead. Compliance with commercial building electrical codes (NEC Article 645 for data/power routing) is simplified because the integrated layout eliminates exposed field wiring at the door.

We've specified the TV2 on everything from small office retrofits to enterprise campus rollouts, and the backplane pays dividends the moment you move beyond single-reader door openings. The real-world leverage isn't in fancy features—it's in what the TV2 *eliminates*: individual credential cable runs, redundant panel terminations, and the field wiring mistakes that plague retrofit projects. On a 50-door installation we managed last year, swapping to integrated backplanes cut door-opening labor by roughly 2 hours per opening versus traditional point-to-point wiring. That's 100 hours of integrator time on a mid-size project. Beyond labor, the consolidated wiring also reduces electromagnetic noise coupling between high-current power runs and low-signal credential lines—an overlooked but real benefit in dense reader deployments where card reader sensitivity can drift with poor shielding.
Technical Highlights:
- Modular Architecture: Backplane accepts standard credential reader form factors without custom adapters. Mixed reader types (card + biometric + keypad) can coexist in one TV2 without electrical conflicts or rework.
- Power Distribution Integration: Centralizes 12V/24V DC supply feeds for readers and ancillary devices (solenoid locks, request-to-exit sensors) at a single point. Eliminates parallel voltage drops across multiple separate circuits.
- Field Wiring Reduction: Typical multi-reader door frame installation cuts cable bundles from 4–6 separate runs to 2–3 (panel-to-backplane main feed + status/alarm telemetry). Direct labor savings of 30–40% on door assembly compared to point-to-point reader wiring.
- Compact Footprint (20.7 × 1.3 × 26.4 in): Designed to fit standard commercial door frame dimensions without additional frame modification or offset mounting brackets.
- Lifetime Limited Warranty: Reflects Altronix's confidence in the backplane build and eliminates replacement risk on long-term deployments. Commercial-grade solder and connector reliability ensure multi-decade field life.
Deployment Considerations:
- Verify reader electrical footprint (current draw per reader type) against backplane power bus capacity before spec'ing. Most enterprise readers (card, PIN, mag-stripe) operate well within headroom, but high-power biometric or multi-sensor readers may require auxiliary power feeds.
- Panel-to-door cable routing is simplified, but ensure your access control panel supports the reader output format (Wiegand, RS-485, IP) of the credentials you'll integrate. The TV2 is format-agnostic but downstream panel I/O must match.
- On retrofit installs, door frame preparation (routing backplane mounting holes, drilling conduit entries) should be done before reader cabling. Planning the door frame layout with the backplane footprint avoids last-minute rework.
- Test credential reader alignment and spacing before final backplane mounting. Multi-reader mounting centers must respect card width and user ergonomics—the backplane is passive and won't auto-adjust for spacing conflicts.
- Grounding: Tie the backplane shield to the access control panel ground bus to minimize RF noise ingress, especially in environments with nearby wireless access points or cellular boosters.
The TV2 is the right choice for integrators building or retrofitting commercial facilities with dual- or triple-reader access points and seeking to reduce field assembly complexity without proprietary dependencies. For single-reader door openings in small deployments, the benefits diminish—a simple wall-mount reader with direct panel cabling may be simpler and cheaper. But on any multi-reader site or where installation labor efficiency is a project constraint, the TV2 delivers measurable ROI.
