Brightness measurement
The presence detector measures artifi cial light and daylight
that is refl ected below the detector. The light measurement
area maps a rectangle of about 1.8 x 3 m at table height. The
installation location is the reference point for the lighting
level. Direct light infl uences the light measurement. Avoid
placing fl oor lamps or suspended lighting directly below the
detector. If the brightness measurement is deactivated, chan-
nel A light only switches depending on presence (brightness
setpoint value set to "on" via potentiometer, or set to "mea-
surement off" via remote control).

Suitable lamps
The presence detector is designed for the operation of fl uore-
scent, compact fl uorescent, halogen and incandescent lamps
as well as LEDs. The maximum number of switchable lights is
restricted due to the high inrush current levels of the EBs and
LED drivers. The use of an external contactor helps with large
loads. Parallel switching enables allocation of load to several
Masters. All switched loads must be properly suppressed.
6. Installation
Flush-mounted fi tting
The presence detector is fl ush-mounted using a size 1 stan-
dard fl ush-mounting installation socket.
Ceiling installation
A ceiling installation unit 73A is available for simplifi ed ceiling
installation of the presence detector (see accessories). This
also ensures cord grip and contact protection. The installation
diameter is 72 mm (drill diameter 73 mm).
