Vanpee & Westerberg Ad600 acoustic detection

The AD600 is a presence detector for energy-saving lighting control. By monitoring sounds from two different areas of frequency and analysing them, "presence" is detected. The lighting is switched on by the inaudible "sounds" with low frequencies which arise when a door opens. The lighting is then kept switched on by higher sound frequencies from footsteps and speech. The main function is automatic activation/deactivation of the lighting in the event of presence/absence. Activation/ deactivation can take place in two separate channels, A and B (lighting groups).
