Technical Specifications

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 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 intrinsically safe reading of the inputs. The know-how, used in the present instrument, has simplified ed 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.
