1. Introduction
The FIBARO Double Smart Module (FGS-224) is a compact radio module designed to integrate existing electrical installations into a Z-Wave network. This allows connected devices, such as lighting or airing systems, to be controlled not only by their traditional wall switches but also remotely via a Z-Wave controller, smartphone, or through automated scenes.
Key features include:
- Compatible with Z-Wave and Z-Wave+ Controllers.
- Supports protected mode (Z-Wave network security mode) with AES-128 encryption.
- Advanced microprocessor control.
- Two channels dry contact switch.
- Works with various types of switches (momentary or toggle).

2. Safety Information
WARNING: Electrical installation should only be performed by a qualified electrician in accordance with all local and national electrical codes. Disconnect power at the circuit breaker before installation or maintenance.
- Ensure the power supply is disconnected before handling the device.
- Do not expose the device to moisture or extreme temperatures.
- This device is designed for indoor use only.
- Do not attempt to repair or modify the device yourself. Refer to qualified personnel.
- Observe all local regulations and safety standards during installation and operation.
3. Package Contents
Upon opening the package, verify that the following items are included:
- 1 x FIBARO Double Smart Module (FGS-224)
- 1 x User Manual (this document)

4. Setup and Installation
The FIBARO Double Smart Module is designed to be placed in a wall box, typically behind a traditional wall switch. It acts as an intermediary, receiving control signals from the switch and then controlling the connected load.
4.1. Wall Box Requirements
It is recommended to use wall boxes with a depth of 65mm. However, smaller boxes with a depth of 45mm can also be used if sufficient space is available behind the switch, considering the size of the traditional switch and any additional cabling.
4.2. Wiring Diagram (General Guidance)
While specific wiring diagrams are typically provided in the physical manual or on the manufacturer's website, the module connects to the existing electrical circuit. The wall switch will no longer directly control the load but will send a signal to the module, which then controls the load. The module supports both momentary and toggle switches.
For detailed wiring instructions, please refer to the official FIBARO documentation or consult a qualified electrician.
4.3. Z-Wave Network Inclusion
Once physically installed and powered, the module needs to be included (paired) into your Z-Wave network. The exact procedure varies depending on your Z-Wave controller. Generally, you will put your Z-Wave controller into inclusion mode and then perform a specific action on the FIBARO module (e.g., triple-clicking a button or toggling the connected switch rapidly) to initiate the pairing process.

5. Operating the Module
After successful installation and inclusion into your Z-Wave network, the FIBARO Double Smart Module can be operated in several ways:
- Via Existing Wall Switch: Continue to use your traditional wall switch as normal. The module interprets the switch's action and controls the connected load.
- Via Z-Wave Controller: Use your Z-Wave hub's interface (e.g., smartphone app, web interface) to remotely turn the connected devices on or off.
- Automated Scenes: Integrate the module into Z-Wave scenes or automations. For example, you can set up a scene to turn on garden lights at sunset or activate a sprinkler system based on a schedule or sensor input.

6. Maintenance
The FIBARO Double Smart Module is designed for maintenance-free operation once installed correctly. No user-serviceable parts are inside.
- Keep the device free from dust and debris.
- Do not use harsh chemicals or abrasive cleaners.
- Ensure proper ventilation around the installation area to prevent overheating.
7. Troubleshooting
If you encounter issues with your FIBARO Double Smart Module, consider the following troubleshooting steps:
- Device Not Responding:
- Check if the module is properly powered.
- Verify all wiring connections are secure and correct.
- Ensure the Z-Wave controller is within range and functioning correctly.
- Try re-including the module into your Z-Wave network.
- Intermittent Operation:
- Check for potential Z-Wave network interference from other devices.
- Ensure the module is not overloaded beyond its specified wattage (60 watts).
- Inclusion/Exclusion Issues:
- Ensure your Z-Wave controller is in the correct inclusion/exclusion mode.
- Perform the inclusion/exclusion procedure close to the controller if possible.
If problems persist, contact FIBARO technical support for further assistance.
