I II
III P conductor:
Note on
The cable between two sensors must be no more than 50 m in length. No
more than 25 m to each further sensor. No more than 300 m in total when
installing 10 sensors.

III S conductor:
Note on
Cable length max. 50 m.
Important:
Incorrectly wired connections will produce a short circuit later on in the product
or fuse box. In this case, you must identify the individual cables and re-connect
them. An appropriate power switch for switching ON and OFF can be installed
in the supply lead.
Note for IR 180:
The mounting location should be at least 1 m away from any lights because heat
radiated from these may activate the system.

Note on parallel connection via P conductor:
IR 180 and HF 180 can be connected in parallel. However, a neutral conductor
must be present on each flush box. When using several sensor switches, they
must be connected to the same phase. As many as 10 sensor switches can be
connected in parallel.
Master/Master COM1 (Fig� 4�4)
Master/Master COM1/COM2 (Fig� 4�5)
A parallel-connected configuration also permits the use of several masters. In
this case, each master operates the lighting group in accordance with the level
of brightness it measures. All settings are selected at each master as required.
The switched load is spread among the individual masters.
Presence is still detected collectively by all detectors. The presence output
(HLK, COM2) can be picked off from any master.
Note:
In a master/master system, inverse switching behaviour may occur on pressing
the switch (A) if the IR/HF 180 have different stay-ON times and this has
already elapsed for one sensor. If this situation occurs, you must either wait
until the stay-ON time elapses or perform a User Reset (RC 5) or Reset (RC 8).
When interconnecting IR/HF 180, this risk is reduced by selecting the same
settings for control dials and DIP switches.
