Product Summary
Controlled. Counted. Every Person. Every Direction. 30 Persons per Minute.
The tripod turnstile is the most widely deployed mechanical access control barrier in Bangladesh's commercial and industrial sectors — providing a clear physical deterrent to unauthorised passage while integrating seamlessly with card readers, biometric terminals, and access control management systems. Unlike a simple door with a reader, the turnstile enforces one-person-at-a-time passage and provides an accurate, tamper-resistant count of all persons entering and exiting a controlled zone.
SSAL deploys tripod turnstiles at factory main gates, office building lobbies, campus pedestrian entries, and bank service areas — locations where the combination of physical access control, people counting accuracy, and integration with time-and-attendance systems delivers measurable operational value.
Key Features
- 30 Persons Per Minute Throughput: 2-second cycle time per person — a single tripod turnstile serves up to 1,800 person-passages per hour without queuing, suitable for small-to-medium pedestrian flows
- Integrated Dual Reader Mounting: Factory-machined reader mounting positions on both entry and exit sides accommodate Wiegand and OSDP v2 card readers without external brackets or additional cabling conduit; reader mounting is symmetric for any standard form factor
- Normally Closed (Fail-Secure): Arms lock in blocking position on power failure — prevents unauthorised passage during power disruptions; manual release key enables controlled egress in maintenance scenarios
- Automatic Emergency Release: Fire alarm dry-contact input triggers automatic arm retraction to fail-safe open position — compliant with BNBC 2020 Part 4 egress requirements; no manual intervention required during evacuation
- 304 Stainless Steel Housing: Mirror-polished or brushed-finish stainless steel resists corrosion in Bangladesh's humid climate; maintains professional appearance in high-traffic corporate and retail environments for the full system lifetime
- IP54 Ingress Protection: Protected against dust ingress and water splash from any direction — suitable for covered outdoor installations at factory main gates and campus pedestrian entries
- Bi-Directional People Counting: Accurate count of passage events in both directions — data exported to time-and-attendance systems, occupancy management platforms, and access control audit reports
- LED Pass/Deny Indicator: Clear green/red LED bar visible to approaching user — eliminates uncertainty about access decision without requiring attention to a separate display screen
- Anti-Tailgating Sensor: Infrared sensor array detects multi-person passage attempts; triggers alarm output to access control panel and reader without mechanically obstructing the second person (safety-compliant approach)
- Cabinet Lock: Internal mechanism cabinet secured by key lock — prevents tampering with the drive mechanism and control board by unauthorised persons
- Adjustable Arm Rotation Speed: Configurable arm rotation speed and resistance — set for user comfort and appropriate resistance at high-security versus standard-security locations

Typical Applications
- RMG Factory Main Gate: Controls worker entry and exit for shift management; people counter provides real-time occupancy data for fire safety compliance and BGMEA/RSC compliance reporting; integrates with biometric time-and-attendance system
- Commercial Office Building Lobby: Dual-reader configuration for card-in/card-out with turnstile enforcement — prevents piggybacking at the lobby barrier by visitors or contractors
- Bank Branch Service Area: Controls queue flow between public waiting area and service counter — combined with visitor management system for appointment-based access
- University Campus Pedestrian Gate: Card reader integration with student management system; time-zone-based access grants student access during academic hours only
- Hospital Staff Entrance: Segregates clinical staff access from public visitor areas; people counter assists with ward occupancy monitoring
- Industrial Canteen Entry: Fair-access control at staff canteen — ensures only entitled employees enter during designated shift meal breaks
Compatibility & Integration
Tripod turnstiles receive control signals (open/close) via dry-contact relay from any access control panel with relay outputs — compatible with Honeywell NetAXS, Gallagher T-Series, ZKTeco InBio, and SSAL's 8-door IP controller. Reader mounting positions accept readers from ZKTeco, Hikvision, HID, and Suprema using standard bracket adaptors. People count pulse output connects to access control management software or BMS for occupancy reporting.
