Dialler
UK
The built-in telephone dialler of the alarm centre allows the
most varied system messages to be transmitted to various
numbers.
Important: If you are using a DSL splitter as part of your
telephone connection then make sure that this is installed
before the alarm centre. The high-frequency DSL signal can
disturb the transmission.
We recommend the use of the additional alarm outputs for
connecting the optional telephone dialling device to the alarm
centre.
You can now connect the outputs with the alarm inputs of
your dialler. Make sure that the polarity of the alarm input at
the dialler is set to -12V (trigger polarity neg.). Additionally,
please read the instructions of your dialler.
Note the information about additional alarm outputs on the
following page.
Key switch
If programmed accordingly, each zone permits the connection
of a key switch for activating or deactivating the alarm centre.
You can use key switches with pulse contact or permanent
contact. For key switches with permanent contact, note that
the control units are still active and misinterpretations can
occur if a key switch is still active but the alarm centre has
already been deactivated via the control unit. We therefore
recommend the use of key switches with pulse contact.
When the key switch is activated, the exit delay time for the
respective area is activated, following which the alarm centre
is activated. In the case of internal areas, immediate
activation is possible. At reactivation, the alarm centre is
deactivated.
Some key switches have additional LED displays that can be
externally activated. If necessary, these can be connected to
the programmed outputs (OP1).
