We reserve the right to make changes without notice COSTER 7. SITING Carbon monoxide (CO) is produced by the combustion of carbonaceous materials: solids (e.g. carbon, coke); liquids (e.g. crude oil) or gaseous (e.g. methane, propane-LPG). Various types of gas appliances are normally installed in domestic premises:e.g. fireplaces, stoves, gas hobs, ovens, water heaters, etc. Lack of or poor maintenance of the appliances and, above all, of the means of removing the exhaust gases, can create the formation or the return of carbon monoxide in the spaces themselves, thereby creating an extremely dangerous sit ...

ELECTRICAL CONNECTIONS IMPORTANT : The detection system must always be in operation and so the electric power must come directly from the mains supply without the interposition of switches or other devices which could inadvertently render it inactive. For the electric wiring use 1.5 mm2 section cables. 9. WIRING DIAGRAMS Warning: RGS 328 detector is not fi tted with an alarm latching device so that it cannot be used to control Normally-closed gas shut-off valves.

We reserve the right to make changes without notice COSTER The values for concentration and exposure time taken into consideration by the sensor and, consequently, by the de- tector, have been established allowing a large safety margin in order to ensure the safety of the persons involved. The response of the sensor is of the “Dynamic” type: if the concentration passes from one band to another, the time count increases or decreases as a consequence, modifying the response of the detector. If the concentration of gas should return below 0.005% (50 ppm) for more than one minute, the detector returns to ...
