Description

Technical Field

[0001] This utility model relates to testing devices, and in particular to a testing device for fire protection control panels. Background Technology

[0002] Fire protection control panels are important control devices in fire protection systems, possessing monitoring, control, and alarm functions. Specifically, fire protection control panels can receive signals from various sensors, detectors, manual alarm buttons, and linkage devices, and can also output control signals to control and manage fire protection equipment within the fire protection system.

[0003] During the production of fire protection control panels, it is necessary to test the input and output channels of the control panels to ensure that they can receive input signals normally and output control signals correctly.

[0004] In existing technologies, each test requires connecting and disconnecting numerous devices, terminals, and wiring. For output channels, testers also need to connect actual fire-fighting equipment or multimeters to check the status of the output channels. This method is inefficient and error-prone. Furthermore, unstable connections can lead to unreliable test results; incorrect wiring can even cause safety accidents. Utility Model Content

In addition, to make the drawings concise and easy to understand, in some figures, only one of the components with the same structure or function is shown schematically, or only one of them is labeled.

[0060] In this article, "one" can mean not only "only one" but also "more than one". In this article, "first", "second", etc., are used only to distinguish them from each other, not to indicate their importance or order.

[0061] Fire protection control panels need to output signals to control various devices in a fire protection system. For example, when a fire occurs, the control panel needs to output signals to drive audible and visual alarms to sound or light, and to control fire extinguishing devices and emergency lighting. Similarly, the fire protection control panel also needs to receive external input signals, such as input information from other devices, monitoring sensors, and the status of manual alarms.

[0062] There are generally three types of output channels for fire alarm control panels. One type includes two output ports, such as a souper output channel, through which the fire alarm control panel can output control signals to the audible and visual alarms. Another type is the relay output channel, which includes three output ports: a common terminal (COM), a normally closed terminal (NC), and a normally open terminal (NO). The NC and NO terminals are connected to two different circuits, and the fire alarm control panel can selectively activate one of these circuits through the control output. The third type is the I / O input / output channel, which includes three ports: an I / O terminal, an OUT terminal, and an IN terminal. The OUT and IN terminals are used for output and input signals, respectively.

[0067] The testing device of this application can not only test whether the IO input / output channels of the fire control panel can work normally, but also test whether the IO input / output channels can output normally when the triggering conditions are met, and test whether the fire control panel can respond correctly when control signals are input to the IO input / output channels.
