SecuriLine eXtended
One or two addressable loops and the associated detectors and modules of the SecuriLine eXtended technology can be
connected to each SecuriFire 1000/2000 main control unit (B6-BCB12 and B6-BCB13) as well as to the B4-DAI2 and B6-
LXI2 SecuriLine unit.
Further information about the main control units or unit can be found in the following technical documentation:

T 811 067
Notice
The B4-DAI2 meets the specification of the SecuriLine but not that of the SecuriLine eXtended. In addition to the
SecuriLine modules, SecuriLine eXtended modules which support the SecuriLine mode can be operated on the
B4-DAI2 trouble-free.
Warning:
Some BX modules cannot be operated on a SecuriLine (e.g. BX-O2I4).
The SecuriLine specifications always apply.
There is no reference to the BA modules in this document, since at the time of this product release only BX
modules are being sold.

Notice
The properties of the SecuriLine eXtended (e.g. 250 participants per loop) apply only when SecuriLine eXtended
elements are used. Since the SecuriLine eXtended elements are backwards compatible, mixed operation with
elements of SecuriLine is also possible; in this case, however, the performance features of the conventional Se-
curiLine apply to the loop!
