Abstract: A method of challenging an agent alarm for the detection of V and G agentshrough the use of a simulant compound which has no significant toxicity and which will test the three principal components of the alarm, namely the conversion filler, heating element, and the detection cell. The stimulant compound has the general formula ##STR1## wherein R" is a lower alkyl group selected to produce a readily displaced alkylmercapto moiety when reacted with the AgNO.sub.3 and KF of the conversion filter and R is a longer chain alkyl selected to give a volatility similar to that of less volatile G agents.
