General
The CIVIC1 control unit can be used to connect one detector (model UR13 or UR20S) to create gas detection systems in envi-
ronments such as boiler rooms, workshops, warehouses, laboratories etc.; the incorporated alarm relay can be used to control a
solenoid valve or an accessory device (siren, flashing light, extractor, etc.). The installation of a gas or carbon monoxide detection
system does not constitute a release from compliance with all regulations for the installation and use of gas devices and with the
relative safety standards and legal provisions in force for this kind of system. Installation, periodic inspections and maintenance of
devices and systems must be carried out by qualified service technicians.
