Multisensors

These Helvar multisensors are compatible with Designer.

See the Sensors section for details of PIR, microwave and light sensors.

312 Multisensor

The DIGIDIM 312 Multisensor is a compact unit containing the necessary sensors to provide energy saving functions when used in a DALI Stands for Digital Addressable Lighting Interface. Standardised digital protocol for lighting control, allowing communication between control devices and LIUs (control gear). system. It contains a light sensor Detects changes in ambient light., a passive infrared detector (PIR PIR: Passive Infra-Red detector. A type of presence detector, contained within the 311 Ceiling PIR Detector and the 312 Multisensor Module.) and an infrared receiver that allows the Multisensor to be operated by the hand held Helvar Remote controller. The PIR enables the system to detect when a room is occupied and the light sensor measures the level of ambient light available. The infrared receiver and Helvar Remote controller allow the room occupants to set the required light levels and to carry out basic system programming. The Multisensor is designed to push fit into a ceiling or luminaire housing.

315 iDim Sense

The iDim Sense is a luminaire-based DALI multisensor. It combines a movement detector (PIR), remote control receiver (IR) and photocell (CL) in one enclosure and a manual mode selector that allows the user to easily select one of the 6 out-of-box application modes.

441 Occupancy Detector Interface (as PIR Sensor)

The 441 Occupancy Detector Interface allows connection of a customer specified occupancy sensor to a DIGIDIM-DALI system. The input accepts a volt free normally closed contact. The pre-wired encapsulated circuit board is intended for mounting inside the wiring space of the sensor. The 441 also includes a 12 V DC supply (15 mA max.) to power the sensor.

The 441 is designed to be as mechanically simple as possible and does not contain the IR receiver, LED A light-emitting diode (LED) is a semiconductor device that emits incoherent monochromatic light when electrically biased in the forward direction. This effect is a form of electroluminescence. The color depends on the semiconducting material used, and can be near-ultraviolet, visible or infrared. indicator and configuration switch provided with the 440 Input Unit. Also (unlike the 440), the 441’s inputs are not electrically isolated, and any connected switching device A physical item with which you can interact, either directly or via Designer. must be mains rated for safety. See the device's installation instructions for more on this.
