FAQ
Do I need a neutral wire to install the LightCore (1-gang)?
No, the LightCore (1-gang) is designed to operate without a neutral wire. It only requires a live wire connection, making installation much simpler and compatible with existing wiring configurations.
What is the maximum power load the LightCore (1-gang) can control?
The LightCore (1-gang) can control lighting devices ranging from 5 watts to 600 watts. For low-power lamps, a capacitor is included in the kit to be connected in parallel with the lighting device.
How does the contactless touch control work?
When paired with a SoloButton, the system activates when your hand gets as close as 15mm from the button surface. This contactless operation makes it ideal for public spaces and allows control even with dirty hands or whilst wearing gloves.
What is the communication range of the LightCore (1-gang)?
Using Jeweller communication technology, the LightCore (1-gang) can communicate with Ajax hubs at distances up to 1,100 metres in open space, making it suitable for large buildings and warehouses.
Can I automate the LightCore (1-gang) with scenarios?
Yes, the device supports various automation scenarios including reactions to alarms, security mode changes, scheduled actions, temperature and humidity changes, and activation by pressing other LightSwitch devices in the system.
What happens if the device overloads or overheats?
The LightCore (1-gang) features built-in protection systems. If current exceeds 2.6A or temperature rises above +60°C, the device automatically turns off power and sends a notification to the Ajax apps.
