Description

Technical Field

[0001] The present invention relates to the technical field of testing equipment, and more particularly to testing equipment and a method for fire detectors which are easy to start and stop and have a fast detection speed. Background Art

[0002] In the process of building a fire alarm control system, R&D personnel will connect fire detectors for performance testing. During the test, hundreds of fire detectors will be installed on a rack to save space and facilitate movement. If the detector under test is a smoke detector, R&D personnel will light mosquito coils or smoke sticks to generate smoke that triggers the smoke detector to alarm. If the detector under test is a heat detector, R&D personnel will use a hair dryer to generate hot air to create an ambient temperature that triggers the heat detector to alarm.

[0003] Among them, whether it is a smoke detector or a temperature detector, it takes at least 3 seconds to confirm a fire alarm, and a smoke detector may even take longer. Therefore, if 100 detectors need to be tested in one round, the round of testing takes about 5 minutes, and the test efficiency is low. In particular, in order to understand the alarm status of fire detectors under different line lengths or wire diameters, multiple rounds of testing are often required, which will further reduce the test efficiency; in addition, after lighting mosquito coils or smoke sticks, the spread of smoke is disorderly and uncontrolled, causing the entire test environment to be filled with smoke and odor, and there are certain safety hazards.

Obviously, the described embodiments are partial embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0024] Embodiment 1

[0035] like Figure 1 As shown, the emission control component 12 includes multiple groups of third units corresponding one-to-one to the multiple groups of second units; the third unit includes multiple groups of pipeline valves 111 corresponding one-to-one to the multiple groups of transverse pipes 19; the two ends of the pipeline valve 111 are respectively connected to the transverse pipe 19 and the elbow 110; it is easy to use and simple to assemble.

[0036] like Figure 1 As shown, a sealing cap 112 and a tie 113 that binds the transverse pipe 19 and the cap body of the sealing cap 112 are provided at one end of the transverse pipe 19 away from the elbow 110 ; the plug body of the sealing cap 112 is inserted into the transverse pipe 19 , and the cap body of the sealing cap 112 is fixed to the storage rack 10 .
