EBDHS-PRM range is an increased performance PIR Presence Detector, developed for high bay lighting control in areas with demanding spaces and increased mounting heights. It is responsive to the constant shift of an organisation’s lighting needs by being programmable and adjustable to produce an exceptionally accurate detection beam. Three models are available: premium (PRM), direct dim (DD), and analogue dim (AD) all of which will switch a wide range of luminaires. The direct dim variant controls DALI or DSI digital dimming ballasts whilst the analogue dim variant controls 1–10V dimming ballasts.
