Operating Manual 7
The BL4 is a motion detector for ceiling mounting having a circular detection area.
The BL4-C is a ceiling-mounted motion detector with a narrow, elongated detection range especially
for corridors.
Settings can be made with the IR-BL infrared remote control.
3.2 Functions
The general operation of the motion detector is described in the short operating instructions
supplied with the device.
Passive infrared motion detectors register movements of heat sources and convert them into
signals that are evaluated by a processor.
The device is a switching detector. The brightness value below which the illumination is to be
switched on can be freely selected (switch-on threshold).
If the value measured by the light sensor is below the set switch-on threshold, a detected move
-
ment causes the connected illumination to switch on. The follow-up time also restarts with each
newly detected movement. After the follow-up time has elapsed, the illumination is switched off.
The illumination can be switched on or off manually by remote control at any time. The device then
remains switched on or off as long as movement is detected plus the set follow-up time.
The follow-up time is restarted by each movement detected. If no movement is detected during a
follow-up time, the detector returns to normal operation (light is switched on during movement and
remains on until no movement is detected for a follow-up time).
