REHAU INTELLIGENT room sensors operate on a 5v common bus
system. Both the REHAU BA Master Controller has four sets of
identical terminals, which can be used for the connection of the
sensors. Any sensor can be connected to any of these terminals.
Remember to connect + to + and I to I .
- The maximum system cable length using a daisy chain layout is 300
mtr, with a maximum cable length between sensors of 100 mtr.
- The maximum distance a sensor can be from the REHAU BA Master
Controller is 100 mtr. when connected in star configuration. (Refer
to Fig.27)
Only REHAU INTELLIGENT wire room sensors can be connected
to the control system. Only Sensors compatible and supplied by
REHAU Ltd. can be connected to the system.
Under no circumstances should any other type/manufacture of
230v or 24v room sensors be connected to the system.
Connection of such equipment will irreparably damage the
controllers & equipment. Such actions will void all warranties.
