GAS LEAKAGE ALARM TESTING METHOD AND GAS LEAKAGE ALARM

摘要

PROBLEM TO BE SOLVED: To provide a gas leakage alarm testing method for easily and quickly performing a test.;SOLUTION: In this method for testing a fire gas leakage alarm provided with a gas detection element, a heater heating the gas detection element, a fire detecting means, and a controlling means having a function of controlling a heater temperature and a function of inputting detection outputs from the gas detection element and the fire detecting means for detecting existence/absence of detected gas and its heat or smoke on the basis of these detection outputs, the controlling means is provided with a storage means storing a test result and a test switch outputting the storage contents stored in the storage means. In every output sampling timing of the gas detection element, a test voltage forcibly making an alarm condition is impressed to the gas detection element in another timing different from the output measurement timing for determining whether a gas detecting function works normally or not, while to the fire detecting means, the test voltage forcibly making the alarm condition is impressed for determining whether a fire detecting function works normally or not, and these results are overwritten and stored in the storage means. In operation of the test switch, the latest test result stored in the storage means is outputted.;COPYRIGHT: (C)2002,JPO
