STEINEL ST 2978 motion detector

<b>Live life conveniently and save energy too.</b>
More quality of life, more safety and security and more energy saved with intelligent sensor technology from STEINEL.

<b>Light 'ON' / 'OFF' - automatically.</b>
Highly innovative sensors respond to movements and light levels, automatically and instantaneously switching the light 'ON' and 'OFF' again after a preselected time.

Presence Control PRO Dual HF COM1, the high-frequency corridor sensor with COM1 interface for operating light in relation to ambient brightness and presence in corridors and aisles. Sensing movement from the ceiling in either direction, the system operates with 2 special high-frequency sensors that reliably cover both corridor directions irrespective of temperature with a radial reach of 20 m. Reach is proportionately selectable in either direction. Additional functions provide the capability of adjusting to the particular usage situations at potentiometers or by remote control. For example, IQ mode for automatically adjusting stay-'ON' time to room usage, pulse mode for activating a staircase lighting timer as well as DIP switches (semi-/fully automatic mode, button / switch mode etc.). The detection zone can be extended by interconnecting master/master or master/slave detectors. Optionally available remote controls take the effort out of installing and using this system.
