COMPALARM C2C
ALARM SYSTEM
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 5÷250V, 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
• 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 96 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.
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.
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.
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.
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 R8 – 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 R8
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

APPLICATION
C2c is suitable for connection of 12 inputs from normally open or normally closed contacts. The operating alarm
sequences can be easily configured according to ISA specifications. C2c is a compact device, all microprocessor based
logic is embedded in the display unit.
Alarm status are displayed by means of hi-brightness, maintenance free red led.
A printed paper sheet can hold alarm associated text, placed under the front panel polyester foil and retained by an easily
removable frame.
High reliability, continuous self check, fail safe logic are important features for this device that is more than a simple
annunciator and could be used like supervisor.

OPERATION
At power-on or return from power-fail, the alarm system will reach an idle condition i.e. no visual and acoustic signalling.
When an input associated contact changes state the alarm system turn from steady to alarm condition, this means that
visual devices and horn output follows the pre-set sequence operation. The load output will be disabled until reset.
By means of push buttons it’s possible to acknowledge the alarm, silence the horn and reset to normal condition. A
specific push button perform the visual device test, without perturbation to normal operation.
Operating dip-switched are located under the polyester front foil, retained by removable click-in frame and must be
selected before power-on.
Before to place the polyester layer is possible to insert a simple paper sheet with alarm text to be visible through the
transparent windows. This paper could be written, engraved or printed. Templates are available for easy PC printing.
RESET TO FACTORY DEFAULT
Press all the three push buttons on the first and, at the same time, switch ON the device.
