The eSSL ET-2011 heavy-duty tripod turnstile is engineered for straightforward deployment into commercial and industrial physical security architectures. Operating on an integrated 32-bit microprocessor primary controller in semi-automatic mode, the turnstile accepts standard electrical trigger inputs and exposes status output circuits to coordinate with third-party access control systems, time-and-attendance hardware, and site safety loops.
Access Control Signal Integration
The internal 32-bit controller integrates with access validation devices using industry-standard dry contact input signals. Any third-party system capable of providing a momentary normally open (NO) potential-free contact closure can actuate the turnstile drive mechanism.
- Input Control Signal: Dry contact opening signal input.
- Trigger Types: Compatible with standalone access controllers, central panel relay outputs, pushbutton stations, or remote guard desk overrides that switch clean dry contacts.
- Configurable Passage Timing: Integrated opening duration timer adjustable between 5 seconds and 60 seconds, determining how long the unlocking cycle remains active if passage is not immediately initiated.
- Passage Logic: Supports both single-way (unidirectional) and bi-directional traffic configuration, allowing independent authorization signaling for entry and exit directions.
Life Safety and Emergency System Interfaces
Facility life safety compliance requires seamless integration with evacuation and building management networks. The eSSL ET-2011 provides dedicated hardware inputs and outputs specifically allocated for emergency egress management:
- Emergency Switch Input: A dedicated hardware interface accepts an emergency override input from fire alarm control panels, emergency stop switches, or evacuation relay loops.
- Drop-Arm Electromagnet Output: The onboard controller features a drop-arm electromagnet drive output. When triggered by the emergency input or upon power loss, the electro-magnetic release allows the horizontal barrier arm to drop immediately, clearing a free 550 mm passage corridor.
Signaling and Peripheral Status Outputs
To communicate gate status to users and site monitoring systems, the onboard primary controller provides built-in signal outputs for traffic and audit monitoring:
- Direction Indicator Output: Supplies control signals to drive external lane display symbols, informing pedestrians of permitted or restricted passage status for each lane direction.
- Passing Indicator Output: Generates a feedback signal upon successful 120-degree rotation of the tripod arms, suitable for triggering visitor counting hardware, access audit logging, or third-party occupancy monitoring systems.
Electrical Supply and Power Integration
The turnstile mechanism integrates an internal power transformation stage that powers the internal DC electro-magnetic drive and 32-bit control board:
| Parameter | Integration Specification |
|---|---|
| Input Line Power | 100–240 V AC, 50/60 Hz |
| Internal Operational Voltage | 24 V DC |
| Maximum Power Consumption | 30 W |
| Drive Mechanism | DC electro-magnetic drive |
| Operating Temperature Range | -25°C to +70°C |
| Ingress Protection | IP54 rated housing |
| Arm Mechanical Load | Up to 80 kg maximum mechanical arm tolerance |
These standardized electrical interfaces allow security contractors and system integrators to wire the eSSL ET-2011 directly into existing raceways, power distribution units, and low-voltage field junction boxes without proprietary interface adapters.
