Honeywell TK-S014 LonWorks Wiegand Remote Terminal Unit

Product Overview

The TK-S014 is a Temaline-series Remote Terminal Unit designed for distributed access-control architectures within Honeywell security systems. Operating as an RTU A08 node, this module acts as a field-level interface for Wiegand-based readers and supervised digital I/O, communicating over a LonWorks® network to upstream Temaline controllers.

The unit is engineered for reliable reader supervision, tamper detection, and multi-point I/O handling in commercial and industrial security installations where system integrity and fault detection are critical.

Core Functions and Capabilities

The TK-S014 provides a direct interface between access-control readers and the Temaline control backbone. It supports standard Wiegand signaling and is compatible with proximity, smart card, and biometric readers.

LonWorks® fieldbus communication enables deterministic data exchange with Temaline panels and building management systems, ensuring scalable deployment across large facilities.

Built-in supervision logic continuously monitors reader connectivity, power status, and wiring conditions, allowing the system to immediately identify abnormal states such as open circuits or shorted lines.

Reader Interface and Supervision

The module implements comprehensive reader monitoring to enhance system reliability and security.

Supported supervision functions include detection of reader power failure, physical disconnection of the reader, and short-circuit conditions on Wiegand signal lines.

Tamper supervision is integrated at the hardware level. The device can generate alarms when the enclosure is opened or when tamper circuits are interrupted or shorted, supporting compliance with high-security installation standards.

Communication Architecture

LonWorks® communication allows the TK-S014 to operate as a distributed RTU within Honeywell Temaline networks. This architecture reduces wiring complexity while maintaining robust real-time communication between field devices and central controllers.

The module is optimized for stable operation in mixed security and building-automation environments where LonWorks is already deployed.

I/O Management

In addition to reader interfacing, the TK-S014 supports multiple supervised digital inputs and outputs for managing door contacts, request-to-exit devices, alarms, and auxiliary actuators.

Its multi-I/O capability enables a single module to handle a complete access point, reducing panel space and simplifying system expansion.

Mechanical Design and Installation

The device is housed in a compact industrial enclosure suitable for DIN-rail mounting inside control cabinets or security panels.

Its form factor allows dense installation in space-constrained enclosures while maintaining proper airflow and service accessibility.

Environmental and Build Quality

The TK-S014 is built for continuous operation in commercial and light-industrial environments. Industrial-grade components and robust supervision circuitry ensure long-term stability and predictable behavior under varying electrical conditions.

Manufacturing origin may vary by production batch, with units commonly supplied from Honeywell facilities in Italy.

FAQ

Q: Can the TK-S014 be used with non-Honeywell Wiegand readers? Yes. Any reader that follows standard Wiegand signaling and electrical specifications can be connected.

Q: Does this module operate independently without a Temaline controller? No. The TK-S014 functions as a field RTU and requires connection to a Temaline control system via LonWorks®.

Q: Is reader supervision configurable? Supervision behavior is managed through the Temaline system configuration, allowing thresholds and alarm responses to be defined at the controller level.
