Turnstile access control integration by 2M Technology: this case study covers a new construction commercial office deployment in Dallas-Fort Worth — Avigilon ACM, HID iCLASS SE readers, OSDP v2.0, and 9 bidirectional lanes.

Avigilon ACM, HID iCLASS SE, OSDP, and Bidirectional Turnstile Lanes

Project Type: New Construction  |  Sector: Commercial Office  |  Integrator: 2M Technology  |  Location: Dallas–Fort Worth Metroplex

2M Technology designs and installs turnstile access control systems for commercial offices, industrial facilities, schools, government buildings, and secure lobbies. Our team integrates turnstiles with Avigilon ACM, HID readers, OSDP, anti-passback rules, fire alarm release, ADA lanes, and video surveillance systems. This case study shows how we deployed a 9-lane turnstile system for a new construction commercial facility in the Dallas–Fort Worth area.

Why This System Was Needed

The facility required turnstile access control integration at its main lobby and three secondary entry points — each with independent access schedules, anti-passback enforcement, tailgate detection, and ADA-compliant egress. Fixed infrastructure turnstiles were specified for the new construction build, with the requirement that all lane events flow to the facility’s Avigilon ACM head-end alongside existing door access control and video surveillance data.

The project was delivered in two phases to align with construction sequencing. Phase 1 covered the primary lobby during building opening. Phase 2 added the secondary entry points as tenant build-out progressed.

System Architecture — Avigilon ACM, HID iCLASS SE, and OSDP

HID 920NTNNEK00000 iCLASS SE — Reader Specification

The HID 920NTNNEK00000 is a 13.56 MHz contactless reader supporting the full HID Trusted Identity credential stack — iCLASS SE, iCLASS Seos, legacy iCLASS, MIFARE Classic, and MIFARE DESFire EV1. This multiclass support was essential for a new construction site onboarding both new Seos credentials and existing legacy cards during the transition period.

  • Protocol — OSDP v2.0 over RS-485, with Secure Channel Protocol (AES-128 encryption and mutual authentication). Supersedes Wiegand — bidirectional, supervised, tamper-detecting
  • Mounting — Recessed into custom turnstile cabinet side panels; pigtail termination to RS-485 bus running to IDF-mounted Avigilon controller
  • Read range — Up to 5 cm (2 in.) for ISO 15693 / ISO 14443-A/B credentials

Avigilon Access Control Manager (ACM) Integration

The Avigilon ACM served as the command layer for all turnstile access control integration decisions, cardholder management, and audit trail logging. Integration points between the ACM and the turnstile system:

  • Controller hardware — Avigilon intelligent controllers (ACM-8 / Mercury EP series) in the IDF, with reader ports assigned per lane for independent access decisions
  • Supervised I/O — Lane IR beam arrays, gate release actuators, and alarm outputs wired to EOL-supervised inputs and isolated relay outputs on the Avigilon controller
  • Anti-passback — Entry/exit reader pairs enforce location state in ACM — re-entry denied until exit is recorded, preventing credential sharing at the lane
  • Schedules — Lobby hours, after-hours restrictions, and emergency free-egress mode configured in ACM; bidirectional lanes independently schedulable per direction
  • Event logging — Granted access, denied access, forced entry, tailgate alarm, and lane fault all log to ACM with timestamp, cardholder ID, and lane ID
  • Alarm integration — Turnstile alarm outputs map to ACM alarm inputs alongside door and camera events

2M Technology 2MWT-5 Access Control Wing Turnstile Specification

The 2MWT-5 is a high-speed automated wing turnstile engineered for high-traffic environments requiring a balance of rapid throughput and security. It acts as the physical execution point for the Avigilon ACM command layer, providing a robust barrier to block unauthorized entry.

  • Throughput capacity — Optimized for rapid pedestrian flow with a pass rate of up to 35 persons per minute.
  • Rapid response — Ultra-fast unlock time of 0.2 seconds eliminates bottlenecks and ensures zero delay during peak traffic in high-volume lobbies.
  • Intelligent IR sensing — High-density infrared sensor beams monitor the passage area to prevent the wings from closing while a person is in the lane and detect tailgating or crawling.
  • Fail-safe mechanism — In the event of power loss or fire alarm trigger, the wings automatically retract to the open position to allow for unobstructed emergency egress.
  • Construction — The high-grade stainless steel chassis and brushed finish provide a professional look that resists wear and corrosion in busy indoor environments.

Installation and Commissioning

2MWT 5 card avigilon integration IMG 5661 edit

2M Technology coordinated with the general contractor and electrical sub for conduit stub-outs and dedicated 24 VDC circuits prior to turnstile delivery. Footplates were core-drilled and anchored during the flooring phase, with conduit sleeves pre-positioned for below-slab cable routing — no surface wireway in the finished lobby.

All 18 HID readers were enrolled to the Avigilon controllers via OSDP discovery, with Secure Channel Protocol keys provisioned at enrollment. Commissioning validation for this turnstile access control integration included:

  • Anti-passback test — Verified ACM location state tracking and deny-on-reuse at each lane independently
  • Tailgate calibration — IR beam timing thresholds tuned per lane at standard throughput speeds
  • Emergency egress — Fire alarm dry contact verified for full barrier retraction within 2 seconds
  • Event audit — 100% of expected ACM events confirmed: granted, denied, forced entry, anti-passback violation, lane fault
  • Throughput validation — Peak-load passage rate confirmed against facility specification before handoff

Frequently Asked Questions

Common questions about turnstile access control integration with Avigilon ACM, HID iCLASS SE readers, and OSDP:

  1. Can turnstiles integrate with Avigilon ACM?

    Yes. Turnstiles integrate with Avigilon ACM using Mercury EP or Avigilon intelligent controller hardware. Credential readers connect via RS-485 OSDP or Wiegand to the controller reader ports. Gate motor control, IR beam sensor inputs, and alarm outputs wire to supervised inputs and relay outputs. All passage events — granted, denied, forced entry, tailgate — log to the Avigilon ACM transaction database with cardholder, timestamp, and lane ID.

  2. Can HID readers be installed inside turnstile cabinets?

    Yes. HID iCLASS SE readers are designed for recessed and embedded mounting. In a turnstile installation, the reader is recessed into the cabinet side panel with the antenna face flush to the surface. Pigtail cable routes through the cabinet to the RS-485 OSDP bus. Mounting depth and metal clearance are specified during the cabinet design phase to maintain the rated read range.

  3. What is OSDP in turnstile access control?

    OSDP (Open Supervised Device Protocol) is a supervised RS-485 reader communication protocol developed by SIA that provides encrypted, bidirectional communication between access control readers and controllers. Unlike Wiegand, OSDP v2.0 supports AES-128 Secure Channel Protocol encryption, tamper detection, reader status feedback, and LED/beeper control from the access control panel. Avigilon ACM and HID iCLASS SE both natively support OSDP v2.0.

  4. Do turnstiles support emergency egress?

    Yes. Commercial turnstile systems are configured with a dedicated emergency egress dry contact input from the fire alarm control panel. On activation, all barrier panels retract to the fully open position within a defined response time — typically 2 seconds or less. Avigilon ACM can also command free-egress mode via software for scheduled or emergency events, independent of the physical dry contact input.

  5. Does 2M Technology install turnstile systems in Dallas–Fort Worth?

    Yes. 2M Technology is headquartered in Grand Prairie TX and installs turnstile access control systems throughout Dallas–Fort Worth, Houston, San Antonio, Austin, and for commercial projects nationally.
