The fire detection module is installed inside and outside the building to promptly notify the building user of the occurrence of a fire, and in the case of a new house, it must be installed.

Since the fire detection module remains unused for a long period of time unless a fire occurs, it is highly probable that the sensitivity decreases or malfunctions over time, so it is necessary to conduct a periodic test to confirm normal operation.

Most of the fire detection modules installed inside the building are installed on the ceiling of the building. In general, the inspector performs a test by attaching a rod to the bottom of the test device.

Due to this structure, by combining or separating the two powders 31a and 31b, the rotating ball part 33 located in the receiving space 311 can be easily inserted or removed.

In addition, the non-slip part 32 may have an inner space 321 having an open upper surface so as to surround a lower surface, a side surface, and a portion of the upper surface of the plate unit 31. At this time, the non-slip part 32 does not close the accommodation space 311. Because the non-slip portion 32 is formed in this way, the plate portion 31 is not separated into two powders as long as the non-slip portion 32 is coupled.
