Legrand 180° Switch Sensor Single Output with Neutral
The Legrand 78454 is a white 180° lighting management wall mounted PIR switch sensor with neutral from the Mosaic range.
It provides automatic lighting management in areas that benefit from natural light: (e.g. individual and open-plan offices and meeting rooms).
Daylight Lighting Controllers
These controllers automatically turn lights 'ON' and 'OFF' in response to changes in ambient light levels, primarily the transition from day to night and vice-versa. The more advanced types (see note below) have inbuilt logic to minimise false triggering, whereas the remainder have inbuilt time delays or higher 'OFF' thresholds, to prevent on/off cycling. As a general rule, these controllers should be sited such that they are not illuminated, by the light they are controlling. Nominal supply voltage is 230Vac.,Note regarding energy-saving negative-hysteresis controllers,Where figures for the 'OFF' threshold are lower than for the 'ON' threshold, the sensor is designed such that four thresholds are actually monitored. These are: dusk, the middle of the night, dawn and the middle of the day. Monitoring at times other than dusk and dawn enables the sensor to determine what it should be looking for next, minimising false triggering and improving overall controller operation.
