Dialler

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).
