## Summary description

ZAMEL WZM-01/S1 is a twilight (dusk-to-dawn) lighting switch designed for automatic control of luminaires based on ambient light. It operates at 230V AC and is supplied with an external SOH-01 light sensor for mounting away from the device to measure illumination accurately. Suitable for outdoor and indoor lighting automation, energy saving, and timed dusk/day control of street, garden, or facade lights.

## Long description

ZAMEL WZM-01/S1 is a twilight (dusk-to-dawn) lighting switch designed for automatic control of luminaires based on ambient light level. The device operates at 230V AC and is delivered with an external SOH-01 light sensor that can be mounted remotely to measure illumination more accurately than an integrated sensor. The unit is intended for straightforward integration into outdoor and indoor lighting circuits for street, garden, facade and pathway illumination where automatic on/off switching according to natural light is required.
Advantages
The external SOH-01 sensor enables precise measurement of ambient light at the point of interest, reducing false switching caused by local shadows or building heat. The WZM-01/S1 supports dependable dusk-to-dawn operation at mains voltage, simplifying wiring and eliminating the need for manual intervention. Compact design allows installation in junction boxes or distribution enclosures close to the controlled circuit. The device helps reduce energy use by ensuring lights operate only when required and can be combined with other control devices in common lighting installations.
Suitable for
 Automatic switching of street and roadway luminaires
 Garden and pathway lighting control
 Facade and architectural illumination management
 Lighting of car parks, entrances and external building perimeters
Key specifications
 Supply voltage: 230 V AC
 Operating principle: twilight (dusk-to-dawn) switch
 External sensor included: light sensor for remote mounting
 Intended installation: indoor or sheltered outdoor installation in distribution boxes
 Application: automatic control of luminaires based on ambient illumination
How to use
Install the WZM-01/S1 in the electrical circuit feeding the luminaires in accordance with local electrical regulations. Mount the SOH-01 sensor in a location representative of the ambient light that will determine switching, away from artificial light sources and thermal influences. After wiring, verify that the sensor orientation and height provide reliable measurement and test the switch operation across day and night conditions to confirm correct threshold behavior. For safety, disconnect mains power before performing installation or maintenance.
Usage recommendations
Position the external sensor where it receives undisturbed natural light and is protected from direct lamp glare and water ingress; avoid mounting near heat sources or recessed pockets that create shadows. Periodically clean the sensor window to maintain accurate light detection. Combine the twilight switch with appropriate fusing and protective devices in the supply circuit to ensure safe and reliable long-term operation.
