MULTISENSOR FOR ROOMSET 331, 331B
The 331 and 331B Multisensor for RoomSet are the heart of Helvar RoomSet single-room lighting solution for commissioning classrooms, offices and meeting rooms. For the installer, the automatic preset programming allows for swift out-of-the-box installation, with no configuration needed.
RoomSet supports advanced graphical configuration via an easy-to-use Android app that enables a quick and simple setup for different purposes, such as presentations, lectures or conferences, or for daylight-harvesting. For commissioning large numbers of rooms, the RoomSet app allows copying room layouts, thus making the commissioning process faster and consequently more cost-effective.
The Multisensor for RoomSet has a light sensor for constant-light control, and a passive infrared (PIR) presence detector to provide energy-saving functions in a DALI system. It also hosts a microcontroller running RoomSet firmware with Bluetooth® low-energy connectivity to allow tablet-based configuration.
Key Features
- Excellent detection performance through high sensitivity and multidirectional coverage. Automated addressing and defaults programming to allow installer testing. Functional system just by powering on the sensor.
- Drag-and-drop graphical configuration of rooms with an intuitive Android app. Over-the-Air upgrades via the RoomSet app to keep the system up to date with the latest available functionality. Programmable constant-light control for energy efficiency. Cost-effective deployment of large numbers of rooms
