## Summary description

Twilight switch ZAMEL WZM-02/SOS is a 230V AC light control device with external SOS-01 sensor for automatic switching based on ambient light. Designed to turn lighting on/off at dusk and dawn, it suits outdoor and indoor lighting circuits, security and energy-saving applications where automated dusk-to-dawn control is required.

## Long description

Twilight switch ZAMEL WZM-02/SOS is a 230V AC automatic light control device that uses an external SOS-01 sensor to detect ambient illumination and switch lighting circuits at dusk and dawn. The unit is intended for installation in lighting systems where hands-free, light-level dependent control is required. It provides a simple way to automate outdoor and indoor lighting, improve security, and reduce energy consumption by activating lights only when natural light falls below a set threshold.
Advantages
The ZAMEL twilight switch with external sensor separates the sensing element from the switching module, allowing flexible placement of the detector to achieve accurate measurement of ambient light while mounting the switch in a protected location. Operating at standard 230V AC, the device integrates with common lighting loads and supports automatic dusk-to-dawn operation without continuous manual intervention. Its external sensor improves reliability of light detection in shaded or exposed mounting positions and helps avoid false switching caused by localized glare.
Suitable for
Outdoor façade, porch and garden lighting
Street, pathway and parking area illumination
Security and perimeter lighting that requires automatic control
Indoor utility areas with variable natural light, such as stairwells or storage spaces
Key specifications
Supply voltage: 230V AC
Control input: external light sensor (SOS-01)
Intended function: automatic on/off based on ambient illumination
Application environment: suitable for indoor and outdoor lighting circuits when sensor is appropriately positioned
Mounting: switching module installed in protected electrical enclosure; sensor mounted externally for accurate light measurement
How to use
Install the switching module in a dry, protected electrical enclosure and connect to the 230V AC supply and the controlled lighting circuit according to local wiring rules. Place the external SOS-01 sensor in a representative position for ambient light detection, away from artificial light sources that could cause incorrect switching. After connecting the sensor to the module, power the device and verify correct operation at dusk and dawn; adjust sensor location if necessary to avoid premature or delayed switching. Follow all applicable electrical safety regulations and, if unsure, use a qualified electrician for installation.
Usage recommendations
Position the external sensor where it receives unobstructed ambient light and is protected from direct artificial illumination and strong glare. For consistent performance, avoid mounting the sensor near heat sources, reflective surfaces, or under dense overhangs. Periodically inspect the sensor for dirt or obstructions and clean according to manufacturer guidance to maintain reliable light detection.
