A unique Sensor that Maximises energy efficiency and Sustainability
The Smart Multisensor combines passive infra-red presence and absence detection with daylight linked dimming so that lighting usage is related not only to occupation but also to the amount of available daylight. Each sensor can be configured in the most energy efficient manner and set to operate under presence detection mode ie. switching the lighting on when an area is occupied and off when the area is vacated.
Delmatic's Smart Multisensor has been designed to provide presence detection, absence detection and daylight-linking whilst maximising energy efficiency and sustainability. Tis innovative sensor is unique as it has been developed to suit a variety of installation types, including direct connection to the latest Dali digital networks. Smart Multisensor can plug into modular installations, be daisy-chained on a common smart bus or connect to the same Cali buswire that connects Dali luminaires and other digital devices.
The Smart Multisensor can be used in a wide range of applications, whilst suiting many different installation approaches and technologies. The compact dimensions of the sensor allows easy incorporation into luminaires and chilled beams - an increasingly common installation approach as exposed ceilings become more prevalent. Designed for total flexibility, Smart Multisensor can be utilised in commercial office areas where a fast-track, flexible plug-in installation is preferred; in core areas fixed installation from the risers is the norm or installations using digital Dali networks.
There is also an ultra efficient absence detection mode which leaves it up to the individual to energise the illumination from a personal transmitter, IP telephone or web browser, which also turns the lights off once the area has been vacated. The integral photocell ensures that lighting is only on when natural brightness drops below a certain level and needs to be supplemented by artificial lighting. A heartbeat function enables operation of the device to be monitored while the sensor may also be used for security purposes, highlighting motion without energising the lighting.
The unit includes an infra-red receiver that enables users to adjust the illumination to suit their individual needs using a personal infra-red device. The receiver also accepts data on current room temperature/temperature st-point from infra-red thermostats. The data is then used to control HVAC controllers so that lighting, heating and cooling energy can all be linked to occupancy. Within washrooms the Smart sensors can be used not only for the control of lighting but also to control water pumps and valves to ensure proximity detection shut-down of water supplies in unoccupied areas.
The use of sensors for the control and management of lighting is generally accepted to achieve savings of around 45% in yearly energy usage. Combining this with the control of heating and cooling achieves further savings. According to the Carbon Trust, reducing the speed of a fan-coil motor by 20% reduces energy consumption by up to 50% while ASHRAE reports that a widening of the temperature control band by just one degree (in unoccupied areas) achieves 4% energy savings.
