The reliability of fire-prevention devices depends on their maintenance. First, this paper analyzes the effect of reliability of fire-prevention devices in past researches, considering their regulations and features. Secondly this researches about it, and reconsiders the reliability of fire-prevention; the input values in the evaluation of the safety in fire. Finally this proposes how to set up the reliability of fire-prevention devices.
