The SIEMENS ADD5160 6FL7820-8CA16 Dual Reader Interface Module represents the next generation in professional access control technology, engineered specifically for integration with SIEMENS FLN (Facility Local Network) security infrastructure. This advanced dual reader interface module delivers exceptional versatility by supporting both RS485 CerPass protocol and Wiegand/Clock&Data reader connections, making it the ideal choice for sophisticated multi-door security deployments in commercial, industrial, and institutional facilities.

Complete Technical Specifications

Advanced Features & Capabilities

• Flexible Reader Protocol Support: Seamlessly interfaces with RS485 CerPass readers or traditional Wiegand/Clock&Data devices for maximum deployment flexibility
• Extended Voltage Tolerance: Wide 12-32 VDC input range with ±20% tolerance ensures reliable operation across diverse power infrastructure
• High-Current Relay Outputs: Dual independent relays (2A @ 30VDC) control electromagnetic locks, electric strikes, and auxiliary security devices
• Intelligent Input Monitoring: Configurable supervised and unsupervised inputs for REX buttons, door position sensors, and auxiliary security contacts
• Enhanced Enclosure Design: Larger 180mm housing provides superior cable management and installation convenience compared to compact models
• Real-Time Status Indication: Tri-color LED diagnostics for instant visual confirmation of power, communication, and activity status
• Industrial Temperature Rating: Certified for continuous operation in 0-50 °C environments typical of mechanical rooms and outdoor enclosures

Deployment Applications & Use Cases

The SIEMENS ADD5160 dual reader interface module excels in enterprise-grade access control scenarios requiring robust performance and scalability. This module integrates seamlessly with SIEMENS ADD5110 interface modules and the compact ADD5100 reader controllers to create comprehensive multi-door security architectures. For cabinet-mounted installations, consider the ADD5190 dual reader interface in cabinet configuration.

Common deployment environments include corporate office buildings with badge access requirements, manufacturing facilities with restricted production zones, healthcare institutions managing controlled substance storage areas, educational campuses with dormitory access control, and government facilities requiring multi-factor authentication. The dual reader capability enables sophisticated anti-passback enforcement, dual-authentication mantrap configurations, and separate entry/exit credential verification.

System Integration & Network Architecture

Build comprehensive security ecosystems by combining the ADD5160 with complementary SIEMENS automation components. Connect to SIEMENS CP 341 RS422/485 communication processors for integration with SIMATIC S7-300 PLC systems, enabling unified building automation and security management. Extend RS485 network distances using SIMATIC DP RS485 repeater modules for campus-wide deployments spanning multiple buildings.

For hazardous location installations requiring intrinsic safety certification, pair with SIMATIC DP RS485-IS coupler modules. Enhance system reliability through SIEMENS 6ES7151 interface modules that provide galvanic isolation and surge protection. For S7-1200 controller integration, utilize the CB 1241 RS485 communication board to establish reliable serial connectivity.

Installation & Configuration Guidelines

The ADD5160’s generous 180-180mm footprint accommodates high-density terminal connections while maintaining organized cable routing within standard security enclosures. Mount the module on DIN rail or directly to enclosure backplanes using integrated mounting provisions. The enhanced depth (60mm) provides ample clearance for terminal blocks and wire management accessories.

Configure reader protocol selection during initial commissioning through FLN controller software. RS485 mode supports up to two CerPass readers on a single twisted-pair bus with automatic address assignment. Wiegand mode provides two independent channels for traditional 26-bit or 37-bit Wiegand readers. Input supervision settings allow configuration of normally-open, normally-closed, or end-of-line resistor monitoring for enhanced tamper detection.

Common Technical Questions

Q: What distinguishes the ADD5160 from the ADD5100 interface module?
A: The ADD5160 features a larger 180-180mm enclosure (versus 125-125mm for the ADD5100) and weighs 0.5kg compared to 0.3kg. The increased size provides superior cable management for complex installations with multiple auxiliary devices.

Q: Can I mix RS485 and Wiegand readers on the same ADD5160 module?
A: No, the module operates in either RS485 mode (supporting up to 2 CerPass readers on one bus) or Wiegand mode (supporting 2 independent Wiegand readers). The protocol is selected during configuration and cannot be mixed simultaneously.

Q: What is the maximum RS485 cable distance for reader connections?
A: Standard RS485 topology supports cable runs up to 1200 meters (4000 feet) using quality twisted-pair cabling with proper termination. For extended distances, deploy RS485 repeater modules to maintain signal integrity.

Q: Are the relay outputs suitable for controlling magnetic locks?
A: Yes, the 2A @ 30VDC relay outputs directly control most electromagnetic locks, electric strikes, and motorized bolt locks. For high-current magnetic locks exceeding 2A, use external power relays or dedicated lock power supplies with relay-triggered control inputs.

Q: Does the ADD5160 require proprietary configuration software?
A: Configuration is performed through SIEMENS SiPass integrated security management software or compatible FLN controller interfaces. Basic parameter adjustments including input supervision, relay timing, and reader protocol selection are accessible through the controller’s configuration menus.

Q: Can the auxiliary inputs monitor door forced-open or door-held-open conditions?
A: Absolutely. The dedicated door contact input plus three auxiliary inputs support comprehensive door monitoring including forced entry detection, door-held-open alarms, and request-to-exit verification. Input supervision modes detect wiring faults and tamper attempts.
