Twilight sensor - activates stand-by mode during the day

The twilight sensor puts the SEQUA LED control units into an energy-saving stand-by mode during the day.

In stand-by mode, in addition to the automatic lighting, the approach and ambient lighting are also switched off during the day. This helps to avoid unnecessary energy consumption of your staircase lighting when the ambient brightness is sufficient. When darkness falls - with an adjustable threshold value - the LED control unit becomes active again and all functions are reactivated. 

The brightness sensor is supplied in a particularly robust version, as it is also used in industry. Thus, the sensor is housed in a sturdy plastic housing, which protects it from contact and damage. The housing also makes it easier to install the sensor: only a 9 mm hole needs to be provided for mounting. In our Advisor article "And this is how it works" installation video we show how this is done. If it is not possible to mount the twilight sensor in a hole, we also offer optional matching Fascias for switch boxes mounting holes. The twilight sensor is "Made in Germany" - with 5 years warranty.

The installation of the twilight sensor

The twilight sensor can be installed anywhere on the stairs, or even in an adjacent room (with a window). As long as the sensor is not covered by furniture or pictures, or exposed to direct artificial light such as a hallway light, the most visually appealing position is the right solution for placement. 

For optimal function and minimalist appearance, the installation is done separately from the motion sensor for this purpose. This has two advantages: First, the twilight sensor can be placed separately from the stairs - for example, in a storage room with a window - and outside the influence of artificial light - such as hallway lighting. This way, the twilight sensor does not react unintentionally to the switching on of the ceiling or hallway lighting and your staircase lighting remains active even when artificial light is switched on. On the other hand, the valuable appearance of the only visible component of the automatic system - the motion sensor - is not impaired by avoidable components. 

The alternative to the twilight sensor is a switching of your automatic staircase lighting via an astro time relay. This is connected directly to the LED control unit and does not require any additional sensors or sensor lines. The staircase lighting is then switched according to the sunrise and sunset times - calculated daily and according to the season. All details can be found in the Article description of the astro time relay.
