• FROM-AP: terminals receiving telephonic connection from the control
panel. This must be connected to the control panel connection which this
uses to provide a line to the subscriber numbers.
Choc block connection to the Public Switched Telephone Network
• PSTN: access terminals to the public switched telephone network. This
connection is supervised. In cases where there is a failure, the analog
output activates.
Choc block connection to the client telephone handsets
• PHONE: terminals providing telephonic connection to the telephone
handsets possessed by the client at home or at installations.
Choc block associated to dry contact outputs OUT1 and OUT2
• OUT1 NC-C: terminals whose state is normally short-circuited. On
activating the output, these terminals stop being short-circuited. Short
circuit is carried out through an electric-mechanical relay. The technical
data for this can be found in appendix V.3.
• OUT1 NO-C: terminals whose state is normal open. On activating the
output these terminals pass to a short circuit state. Short circuit is carried
out through an electric-mechanical relay. The technical data for this can
be found in appendix V. 3.
This output is also related to the input status of the PSTN and LAN and with
the IP connectivity status with the alarms reception center. When there is IP
connectivity, the OUT NO terminals will be in their normal state i.e. open. If
there is a failure in IP connectivity, then these terminals pass to a closed
state.
The IPDACT-UD output is a status indicator for the IPDACT-UD. It
is necessary to connect this said output to a panel zone which, as
this is active, compulsorily generates an audible and visible signal,
as well as sending the trouble signal to the alarm reception center.
•
OUT2 NC-C: terminals whose state is normally short-circuited. While the
CPU is working properly these terminals are open. Short circuit is
carried out through an electric-mechanical relay. The technical data for
this can be found in appendix V.3.
• OUT2 NO-C: terminals whose state is normal open. While the CPU is
working properly these terminals are in a short circuit state. Short
circuit is carried out through an electric-mechanical relay. The technical
data for this can be found in appendix V. 3.
