Product information

Description

Quick to Access 3 Working Modes: self-locking, interlock and inching modes are available directly in the app. The device controls up to four channels, allowing separate or coordinated control of connected lights and other electrical loads. It supports voice control through Alexa and Google Home and uses a flame-retardant PC shell for enhanced safety.

Advantages

The module provides three distinct control modes accessible from the mobile app: independent on/off for each of the four channels (self-locking), mutually exclusive channel operation (interlock), and timed automatic turn-off after a preset interval (inching). Voice integration with Alexa and Google Home enables hands-free control. The flame-retardant PC enclosure increases protection for connected devices during normal operation.

Key specifications

Channels: 4 independent channels
Control modes: self-locking, interlock, inching
App control: mobile app access to all modes
Voice control: compatible with Alexa and Google Home
Enclosure: flame-retardant PC shell for enhanced safety

How to use

Install and wire the module according to the manufacturer’s instructions, then add the device to the mobile app. Use self-locking mode to switch each channel on or off independently. Enable interlock mode when one channel should turn on while others turn off. Set inching mode to keep a channel on for a defined time interval before it automatically turns off. Connect the device to Alexa or Google Home in the respective apps for voice control.

Recommendations

Use self-locking mode for independent lighting control, interlock for mutually exclusive functions (for example, selecting one output at a time), and inching for corridor or staircase lighting where automatic shutoff is required. Ensure proper installation and observe electrical safety; rely on the flame-retardant enclosure but follow safe wiring practices.
