Evaluation of fire detector performance reveals itself as a multiple attribute decision-making problem. The hierarchical structure of evaluation process is presented. The evaluating elements including fire detection, surrounding adaptation and immunity to false alarm or nuisance alarm are proposed as the main attributes of the whole process. The whole evaluation pattern is designed in detail and test methods of evaluation are also in action. The mathematical model is based on AHP （analytical hierarchical process）. Because the weights can not be treated as integer, then triangular fuzzy number is introduced to deal with the problem. The performance of the algorithm is demonstrated by the example. The mathmetical model and test methods can help to deal with the fire supervising for the authorities and the selection of products for end users.
