The Alvarado SU5000 optical turnstile, part of the dormakaba Group, is a sophisticated bi-directional access control system designed for facility access control and patron movement detection. It utilizes integrated optical sensors to control access and detect unauthorized users. The SU5000 is available in various configurations, including single-lane and multi-lane setups, and can be customized with different barrier widths (28" and 36" lanes) to suit specific site requirements.
Function Description:
The SU5000 turnstile provides controlled passage modes, including Controlled Passage, Free Passage, and No Passage. In Controlled Passage mode, the barriers are closed and only open upon receipt of an authorization signal from an access control system. The barriers will close after the user has passed through or if no passage occurs after activation. Free Passage mode allows users to pass through without authorization, with barriers opening automatically upon user detection. No Passage mode keeps barriers closed, prohibiting passage, and will open only for a fire alarm input.
The turnstile supports bi-directional traffic, allowing for flexible configurations such as controlled entry/controlled exit, controlled entry/free passage exit, and various morning/evening traffic scenarios. It integrates with an access control system via dry contacts and TCP/IP interface, enabling communication for authorization signals, alarms, and status updates.
Important Technical Specifications:
- Power Supply: A single 24V power supply is installed in the Main/Center cabinet, providing primary power to 24V low-voltage power for motor operation. Motor controller boards reduce the 24V power to 5V and 12V for turnstile controller, optical sensor, and light operation.
- Motors: Each turnstile has two brushless DC motors, combined with planetary gearbox and electro-mechanical brake, to drive the moving barriers.
- Sensors: The system incorporates multiple safety sensors per cabinet, including free passage sensors (infrared transmitters and receivers on both ends of the turnstile), operational sensors (infrared transmitters and receivers inside the top channel of the cabinet), and safety sensors (infrared transmitters and receivers on the center portion of the cabinet). These sensors detect users, objects, and monitor the path of opening barriers.
- Barriers: Motorized barriers are acrylic with a special abrasion-resistant coating, available in three heights: 35", 46", or 69". Barrier height options are 0.5" (13mm) thick for low and mid-height barriers, and 0.75" (19mm) thick for high barriers.
- Card Readers: The turnstile can accommodate 1D/2D barcode readers or credential readers integrated into the right-hand leg of the turnstile, beneath the lid, communicating turnstile status to the user.
- Connectivity: The SU5000 connects to a facility network via an Ethernet cable, allowing for remote configuration and monitoring using UltraVNC Viewer software. An "interconnect cable" (8', 13', 20', or 40' lengths) connects the Main cabinet to secondary and center cabinets in multi-lane configurations.
- I/O Control Board: The Main cabinet houses the CPU, I/O control board, two motors and two motor controller boards, power supply, safety sensors, and a power switch. The I/O control board terminal strips provide various inputs and outputs for access control system integration.
Usage Features:
- User Status Display: An illuminated yellow LED indicates the turnstile is ready for card presentation. A green LED indicates passage is allowed, and valid credentials have been presented. A red LED indicates passage is prohibited. Flashing green or red LEDs indicate Free Passage mode or an alarm condition, respectively.
- Open/Close Status Light: An illuminated green bar indicates the turnstile is open for use. A red bar indicates the turnstile is closed for use, or an alarm condition.
- Operational Sounds and Alarms: The SU5000 is pre-configured with various operational sounds and alarms played from speakers mounted in each leg of the Main and center cabinets. These sounds include "Access Granted," "Access Denied," "Unauthorized Presence," "Blocked Sensor," "Unsafe to Open," "Tailgating," "Barrier Breakaway," "Barrier Impact," "Barrier Held Open," "Motor Fail," and "Start-Up Complete."
- Powering On/Off: The turnstile is powered on/off using a key switch located inside the base cover of the Main and center cabinets. After power-up, the SU5000 enters the previously configured passage modes or the passage modes defined in GateKeeper.
- Lane Key Control (Option): Optional 3-position lane key control switches can be installed per turnstile to override passage modes (Controlled Passage, Free Passage, No Passage) for specific directions of travel.
- GateKeeper Integration: An optional web-based application that allows Alvarado optical turnstiles to be controlled from multiple devices, providing scheduling, monitoring, and advanced access control features.
Maintenance Features:
- Preventative Maintenance: Regular cleaning of stainless steel surfaces, color powder coat finished cabinet surfaces, moving barriers, side panels, and sensor lens covers is recommended to maintain visual appearance and optimal performance.
- Cleaning: Stainless steel surfaces can be cleaned with a commercial stainless steel cleaner or polish. Color powder coat finished cabinet surfaces can be cleaned with a soft damp cloth. Acrylic surfaces of moving barriers and side panels should be cleaned with a soft cloth and acrylic-specific cleaning products.
- Internal Maintenance: Internal maintenance involves removing canned air dust from printed control boards and cleaning dust from optical sensors.
- Weekly Safety Check: A weekly safety check ensures the turnstile is safe and ready for user operation. This includes verifying barrier alignment, attachment of barriers, passageway clearance, test activation, and proper response to unsafe to open/exit conditions.
- Troubleshooting: The manual provides a comprehensive troubleshooting guide for common issues such as "Unit will not turn on," "Constant auditory alarming," "Barriers operate erratically," "Barriers do not move," "Blocked Sensor/Auditory Alarms," "Barriers either stay open or start to close then open back up," and "Barriers do not align in closed position." Solutions include checking fuses, I/O control board, digital position encoder, and motor controller board fuses.
