COMPALARM C2C

GENERAL
• Compact alarm system, with a basic module
of 12 signals
• Multiple modules coupling possibility
• Easy printing of the alarm points description
• Opto-isolated inputs for 24,48,115,
230 Vac/dc NO or NC
contacts, which can be set point by point
• Signal power free inputs
• 7 alarm sequence possibilities according with
ISA S 18.1
• Easy and fast programming by dipswitches
• ”First out” feature for recognizing the first
tripped alarm
• ModbusRTU protocol via RS485 serial port
• ModbusTCP protocol via Ethernet module
• Interconnected systems for Alarm Management, distributed in various units
• High safety and reliability
The COMPALARM C2C is a very compact and efficient
alarm system, suitable for 12 points connection, with NO
or NC input contacts and LED signals. This system is
supplied in a 6 mm x 96 mm enclosure for flush
mounting. An easy alarm’s description printing, easy
wiring by plug-in terminals and a good front protection
degree, come to complete this attractive alternative.
The COMPALARM C2C is being manufactured, in such a
way to be capable to ensure an intrinsically safe reading
of the inputs. The know how, used in the present
instrument, has simplify the circuits up to a maximum,
granting a high reliability and safety for avoiding false
signals. It has also enabled to have a high immunity
degree against external disturbance and signal
management with increased voltage capability.
The electronic management system allows to program
the alarm behavior, according with the ISA S 18.1
standard, so as the inputs and outputs position.
IIIII INPUTS - The COMPALARM C2C has 12 inputs that
can be set as NO or NC by dipswitches. All inputs are
optoisolated and can be supplied with any voltage
between 5 ÷ 250V ac/dc. It has been also foreseen the
inputs for acknowledgement, test and reset push
buttons.
IIIII OUTPUTS - The outputs are fitted with two voltage
free contacts relays. One of them is intended for the
acoustic or alarm signaling and the other for a
cumulative of alarms (normally excited or diexcited in
case of alarm) for process activation approval,
in presence of one active alarm (or non resetted yet) at
least.

The mentioned relay will also react due to a lack of
power supply or due to its internal malfunction.
IIIII INTERCONNECTION WITH OTHER MODULES - With
the wiring of one cable through other similar devices, it is
possible to enlarge the system, which will work as an
unique system, in order to grant a correct operation of
the various alarm sequences, “first out” function
included. In such a case, the outputs can be detected by
any of the interconnected modules.
IIIII PROGRAMMING AND OPERATION
Each COMPALARM C2C module accepts up to 12
contacts, with a common pole, either open or closed in a
rest position, which can be set for each input by
dipswitches, placed behind the alarms description panel.
The activation, memory and reset modes can be selected
among the 8 most common sequences, according with
the ISA 18.1 standard ISA A – ISA M – ISA R – ISA M5 –
ISA F1A – ISA F1M – ISA F3 A.
The mentioned sequences have following basic
sequences:
ISA A Automatic reset.
ISA M Manual reset.
ISA R Ringback.
ISA M5 Signaling like ISA-M, but without flashing, when
optical signaling.
ISA F1A Automatic reset “first out” with no subsequent
alarm state.
ISA F1M Manual reset “first out” with no subsequent
alarm state.
ISA F3A Automatic reset “first out” with first out flashing
and reset pushbutton
