The PIR presence detector talis II PC 40-5-1i is the device of choice wherever you need to illuminate long corridors, for example in hotels or office buildings. It covers a range of 40 metres length and 5 metres width. It switches the connected electric consumer automatically depending on the ambient brightness and only when there are people present. The remote control makes adjusting settings really simple. Nobody will need to climb any ladders, even if you do need to change anything later. The talis II PC 40-5-1i is suited for surface mounting, flush mounting and for installation in a suspended ceiling.
