Siemens SpABuilding TechnologiesCE1N7609e / 11-07-20081/4s 7 609INTELLIGAS®Gas leak detectorsfor residential and similar useIn conformity with Standard EN50194 LYA14..____________________________________________________________________________________________Electronic gas leak detectors with one threshold for residential use. 230VAC powersupply, SPDT relay output suitable for 230VAC solenoid valve or other signalling oractivating devices.____________________________________________________________________________________________The LYA14.. detectors have been engineered to provide both optical and acoustical alarmand activate a solenoid valve for shutting off the gas flow (or other auxiliary devices) inpresence of dangerous concentration of:• methane (CH4)• LPG____________________________________________________________________________________________When the detector is supplied with 230VAC, it runs a preheating phase that lasts about 60s.During this period the detector is inactive. After the preheating phase the detector enters innormal operating condition. In case of a gas leak, when the gas concentration in the airexceeds the preset threshold, the detector signals the alarm condition lighting on the redLED, activates the buzzer and energises the internal relay for closing the manual resetsolenoid valve in order to cut the flow of gas. When the cause of alarm has been removed,the detector returns to normal operation. To re-establish the normal gas supply condition itis necessary to open manually the solenoid valve acting on its appropriate reset device.____________________________________________________________________________________________Description : Type :Methane gas (CH4) detector LYA14.GLPG detector LYA14.PUseOperationAvailablemodels
