Usage examples:
Circuit 1 = NC-COM contact of an alarm panel unit alarm relay.
Circuit 2 = Panic button.
Circuit 3 = Technological alarm from alarm panel unit.
Circuit 4 = NC-COM contact with 24h/day protection from short circuit or cutting.
Inputs IN5, IN6, IN7 and IN8 (Reset input)
Inputs 5, 6, 7, and 8 can be linked only as NC. Look at circuit 1.
RESET Input
CALL CYCLE RESET
The RESET terminal must be connected to
an output of the alarm panel unit signalling
the status of the system to obtain automatic
cancelling of the call cycle in case of
disarm. The signalling of the alarm panel
system status must be stable. To make use
of this feature the DIP switch 1 (LOCAL
RESET) must be on.
The CT952 can manage both signalling of
the system status, either positive or
negative, depending on the position of the
jumper JP6.
The RESET works with a positive potential, therefore if the command is negative jumper JP6 must be
closed to insert a PULL-UP resistance.
INPUT RESET
The status of the RESET input may also be managed as a double call event and therefore be used
as a double-status input in order to generate call events ("RESET open" and "RESET closed").
SYSTEM STATUS
When the RESET terminal is connected with an output signalling the status of the alarm panel unit,
its status also indicates whether the alarm panel system is armed or disarmed. In this way the CT952
gives a feedback to the user on the status of the alarm panel unit by checking the RESET status.
When the DIP-switch 4 (SYSTEM STATUS) is ON this feature can be used to control remotely the
alarm panel system.
