Product information

Description

4CHR3 and 4CHPROR3 are 4-gang Wi‑Fi smart switches designed to add remote and automated control to conventional home circuits. These modules support three operating modes—self-locking, interlock and inching—accessible directly from the companion app. They work with Alexa and Google Home for voice control and are housed in a flame-retardant PC enclosure for increased safety.

Advantages

The smart switch lets you control four loads independently or configure channels to operate in interlock mode so one channel turns on while others turn off. In inching mode a channel stays on for a preset interval and then switches off automatically, useful for corridor or staircase lighting. App access provides quick mode selection and remote switching, while voice assistant compatibility enables hands-free operation.

Key specifications

Model: 4CHR3 / 4CHPROR3
Number of channels: 4
Connectivity: Wi‑Fi (works with Alexa and Google Home)
Operating modes: self‑locking, interlock, inching
Enclosure: flame‑retardant PC

How to use

Install the switch in accordance with local electrical codes and the manufacturer’s wiring diagram. Pair the device with the mobile app, then select the desired operating mode for each channel: self‑locking for independent on/off control, interlock to make one channel active while others are turned off, or inching to set a timed on interval. Use the app or connected voice assistant to switch channels remotely or by voice commands.

Recommendations

For safety, have a qualified electrician perform the installation and ensure the connected loads do not exceed the switch’s rated capacity. Use inching mode for temporary corridor lighting and interlock mode for motorized blinds or garage doors where opposite actions are required.
