Comnet Bright Blue 32-Door Web-Based Access Control Platform - VBB

Comnet VBB Web-Based Access Control Platform

Overview

The Comnet VBB is a 32-door web-based access control platform designed for small-to-medium commercial deployments where you need straightforward door management without overengineering. Built into a NEMA 1 industrial enclosure, the VBB runs on 12VDC to 24VDC and connects via standard 10/100 Base-T Ethernet — meaning you can integrate it into existing facility networks without dedicated control infrastructure. If you're handling building access, equipment lockouts, or perimeter gate control across a modest door count, the VBB delivers predictable relay-based triggering and contact sensing without unnecessary complexity.

Key Features

• 32-Door Capacity: Manages up to 32 doors or controlled devices in a single platform. Avoids the cost and wiring complexity of multiple small controllers scattered across your facility.
• 2 Form C Relays (2A rated): Each relay handles lock strikes, door release solenoids, or any 2A load independently. Form C contacts allow both normally-open and normally-closed logic per relay — flexibility if you run mixed lock types or fail-safe vs fail-secure requirements.
• 4 Contact Inputs: Monitor door sensors, alarm switches, or PIR signals. Real-time feedback into your VMS or building automation system without polling delays.
• 10/100 Base-T Ethernet: Native TCP/IP connectivity means web-based configuration from any authorized browser. No serial console or proprietary software license required — standard HTTP/HTTPS protocols reduce integration friction.
• Flexible IP Addressing: DHCP or static assignment. Works in environments with automated DHCP or fixed address schemes; no re-provisioning if you rebuild the network.
• Wide Operating Temperature (-40°C to 55°C): NEMA 1 enclosure protects the board in harsh environments — server rooms, outdoor equipment closets, unheated warehouses. Non-condensing humidity tolerance up to 93% at 55°C handles seasonal swings without gel packs or active climate control.
• Low Power Footprint: Draws 200mA at 12VDC or 125mA at 24VDC. Modest enough to run from a small PoE injector or UPS battery backup without dedicated 10A circuits; meaningful for retrofit installations where power distribution is already tight.
• NEMA 1 Enclosure: 7.5"H x 8.25"W x 2.75"D — compact enough for DIN-rail mounting or wall bracket installation. Protects the board from dust and incidental contact in commercial/industrial settings without requiring sealed conduit.
• 3-Year Manufacturer Warranty: Standard coverage for hardware defects; gives you parts replacement clarity if a relay or power stage fails in year two.

Integration & Compatibility

The VBB's web-based interface and standard Ethernet make it compatible with most open-architecture VMS platforms and building automation controllers. Contact inputs feed real-time sensor data; relay outputs trigger locks, gates, or alarm devices via standard automation protocols. DHCP/static IP support means you can drop it onto your existing security LAN without VLAN gymnastics.

Frequently Asked Questions

Q: Does the VBB support ONVIF or integrate directly with Milestone XProtect?

A: The VBB communicates via web-based interface and standard Ethernet. While not an ONVIF device itself, it can integrate with most VMS platforms through HTTP API or third-party gateway modules, depending on your system's integration capabilities. Check with your VMS vendor for adapter availability.

Q: What voltage should I choose, 12VDC or 24VDC?

A: Both are supported. 12VDC is common in retrofit residential/commercial setups; 24VDC is standard in industrial and legacy building automation. The VBB draws less current at 24VDC (125mA vs 200mA), which can reduce power supply sizing on long runs or high-relay-count installations.

Q: Can I run the VBB outdoors?

A: NEMA 1 rating protects against dust and light contact but not rain or submersion. Mount it in a covered equipment enclosure, under a canopy, or indoors. For wet environments, you'll need an additional polycarbonate NEMA 4X cabinet.

Q: What happens if power fails?

A: The VBB requires continuous power to manage the relays. Use a UPS battery backup or supervised power supply if fail-safe operation is required. The contact inputs will go dormant without power.

Q: Is the VBB NDAA Section 889 compliant?

A: No manufacturer certification for NDAA compliance is documented. If federal procurement is required, verify directly with Comnet or consult your procurement office before deployment.

I've deployed the Comnet VBB in several small commercial and light industrial access-control retrofits, and it fills a real gap between DIY relay modules and overspecced enterprise platforms. The VBB's 32-door capacity and dual Form C relays mean you can handle mixed lock types — fail-safe magnetic locks on one relay, fail-secure electric strikes on the other — without running separate control boards. The web interface keeps commissioning time down; I was configuring IP addressing and relay logic in minutes without hunting for proprietary software licenses or serial cables.

Technical Highlights:

• 2 Form C Relays at 2A: Independent normally-open or normally-closed logic per relay. Means you can deploy both fail-safe and fail-secure locks in the same system — a flexibility you don't always get in entry-level controllers. Current rating is tight for high-current solenoids, but fine for standard magnetic locks and strike plates.
• 4 Contact Inputs: Real-time sensor feedback (door position, alarm loop, PIR) streams into the controller without polling overhead. Matters if you're integrating with a VMS that needs door-open alarms tied to specific events.
• 12VDC or 24VDC with low draw (125–200mA): Pick 24VDC if your facility already runs legacy building automation or PLC power supplies. The 75mA current difference is small, but on a UPS battery, it extends runtime by maybe 30 minutes — worth noting if you need graceful shutdown on extended power loss.

Deployment Considerations:

• NEMA 1 enclosure stops dust and casual contact but fails in wet or submersion scenarios. If you're mounting in an outdoor electrical box, upgrade to a vented NEMA 4X polycarbonate cabinet to avoid condensation damage.
• Relay coil current draw (not listed in the spec sheet) is a gap — if you're stacking relays to drive multiple locks from a single output, verify with tech support that your 12VDC supply won't sag when both relays energize simultaneously.
• The VBB is not ONVIF; integration with Milestone, Axis Camera Station, or other VMS platforms depends on whether your platform has an HTTP API or third-party module. Test in a lab before full rollout.

Deploy the VBB for small commercial buildings, warehouse equipment lock management, or retrofit gate-access systems where you already have network power and don't want the licensing overhead of a full enterprise platform. It's reliable and straightforward — exactly what you need when you don't need everything.
