PARADOX KNX Interface

Overview

The EVO-KNX is a professional KNX gateway designed for seamless integration of Paradox EVO and DGP series alarm systems into KNX building automation installations. This bidirectional interface enables real-time communication between security and building management systems through the Paradox PRT3 (or BUS2SER) RS232 communication module, allowing integrators to create intelligent responses to security events throughout the KNX installation.

Technical Capabilities

The gateway provides comprehensive alarm system integration through RS232 communication with the Paradox PRT3 module configured at 9600 baud. Key capabilities include monitoring up to 96 zones with individual KNX group objects for real-time status feedback, and monitoring of 30 programmable outputs (PGM) for flexible alarm-to-KNX event linkage.

Area management supports up to 4 security areas with full arm, partial arm, and disarm control directly from KNX visualization or push-buttons. Each area provides 9 distinct status feedback objects: disarmed, entry delay, exit delay, armed, partial armed, fire alarm, siren on, panic alarm, and intrusion alarm. This granular status information enables sophisticated building automation responses to security events.

The gateway also supports 16 virtual inputs that can be controlled from KNX, allowing bidirectional integration where KNX events can trigger alarm system actions. The scene integration feature automatically recalls KNX scenes (1-64) for each area status change, enabling pre-programmed building responses such as emergency lighting activation during intrusion or comfort scene recall when disarming.

Zone offset configuration supports multi-gateway installations covering up to 192 zones across two EVO-KNX devices, with zones 1-96 on the first gateway and zones 97-192 on the second. Similarly, area mapping allows coverage of areas 1-4 or 5-8 for installations requiring up to 8 area control.

Installation and Configuration

The compact module (66 x 44 x 25mm) requires an external 12VDC power supply which can be sourced from the AUX power supply of the Paradox alarm panel. The RS232 connection between the PRT3 module and the EVO-KNX interface uses the included DB9 connector with no additional wiring required.

Connection to the KNX bus uses a standard KNX bus terminal. The device draws less than 4mA from the KNX bus and less than 6mA from the 12VDC supply. The PRT3 (or BUS2SER) module must be configured to enable ASCII protocol communication and report zone and area events.

Configuration is performed entirely within ETS using the standard Elausys alarm gateway application. The unified ETS application concept shared across all Elausys alarm gateways means integrators familiar with other models can immediately work with the EVO-KNX. Parameters include zone count selection (16/32/48/64/72/96), PGM configuration, area mapping, scene assignments, and user code setup for KNX-initiated arming commands. The free ETS Demo version is fully supported.

Applications

Residential installations benefit from integrated security and home automation, where arming the alarm automatically activates night scenes, presence simulation, and energy-saving modes. Motion detectors from the Paradox system can trigger KNX lighting in corridors and stairwells, adding value to existing security infrastructure.

Commercial buildings leverage the gateway for coordinated emergency response, where fire alarm detection triggers escape route illumination, blind opening, and HVAC shutdown sequences. Integration with KNX visualization systems provides security monitoring from building management dashboards.

Multi-tenant properties use the 4-area support for independent zone control across different building sections, with centralized monitoring through KNX.

Compatibility and Integration

The EVO-KNX is compatible with Paradox EVO and DGP series alarm systems using the PRT3 (or BUS2SER) RS232 communication module. The gateway integrates with any KNX TP installation and is fully configurable using ETS5 or ETS6, including the free ETS Demo version.

Related Elausys products include the PRT3 communication module required for the alarm system connection. The gateway follows the unified Elausys alarm gateway architecture, ensuring consistent integration patterns with HyperVisu visualization servers and other KNX system components.
