OCCUPANCY CONTROL
ABSENCE DETECTION
It is easy to forget to switch off the light, in office, corridor, even at home. And in many other cases, people do not want to have a sensor to switch on the light automatically, for example, when people just quickly pass-by, there is no need to have the light on. The solution is to apply this “absence detector”: motion sensor is employed, but only activated on the manual press of the push switch, the light keeps being ON in the presence, and switches off/dims down in the long absence.
DAYLIGHT THRESHOLD
Sensors provide simple switching of the light based upon occupancy. A daylight sensor is also built-in to prevent the light switching on when there is sufficient natural light.
DAYLIGHT MONITORING
Motion sensors with Daylight Monitoring are able to achieve that luminaire be automatically switched on at sunset and be automatically switched off at sunrise, even without movement triggering.
DAYLIGHT HARVESTING
Right time, right place and the right amount of light. Daylight harvesting is a must in the future lighting norms. Daylight harvesting sensors use daylight to offset the amount of artificial lighting needed to properly light a space, in order to reduce energy consumption and reach the target lux level. This is accomplished using lighting control systems that are able to dim or switch the lighting in response to changing daylight availability.
SYNCHRONISATION
Synchronisation mode is useful when several sensors are connected together to control the same fixtures. By connecting the synchronisation terminals in parallel (maximum 10 units, see diagram), no matter which sensor detects motion, all sensors in the group will turn on the lights (ambient natural light is below daylight threshold). The detection area is widely enlarged in this way while other settings such as hold-time, stand-by period, stand-by dimming level and daylight threshold on each individual unit stay the same.
