Description

Portable Fire Detector Tester

The present invention relates to a fire alarm device that sounds an alarm so that many people are aware when a fire occurs, more specifically, the operation of the fire detection device for detecting the smoke or heat generated by the fire to operate the alarm device Portable tester of fire-sensing device that can check the status.

In general, a fire is a disaster that takes a lot of property and lives, and in the case of such a fire, many people are aware of the fire condition, and the average building is equipped with a fire alarm system that sounds an alarm.

The fire alarm device is composed of a fire detection device (or fire detector) that outputs a predetermined signal by detecting smoke or heat when a fire occurs, and an alarm device that generates an alarm sound by receiving a predetermined signal from the fire detection device. do.

In general, fire detectors are known heat detectors using heat generated by fire and smoke detectors to capture smoke. 1 is a schematic view showing an installation state of the heat detector of the conventional fire detection apparatus, Figure 2 is a schematic diagram showing an installation state of the smoke detector of the conventional fire detection apparatus.

As shown in Fig. 1 and Fig. 2, the LED (1) (2) installed on the outer peripheral surface of the detector is turned on when the degree of heat or smoke reaches a certain degree, which means that the detector starts to operate.

Among such fire apparatuses, there are bimetal type, thermal semiconductor type and thermocouple type.

The bimetal thermal sensor is a structure in which a low-expansion metal and a high-expansion metal are bonded to each other. When the bimetal fixing one end receives heat, the bimetal thermal sensor uses a displacement that changes in proportion to the temperature when the bimetal fixing the one ends receives heat. The thermo-semiconductor or thermocouple sensing knowledge uses the Seebeck effect.

In addition, a smoke detector includes a photoelectric type, and a photosensitive type or a scattered type is used here.

The photosensitive smoke detector uses light attenuated by the smoke, and is activated when the smoke of the detector reaches a predetermined concentration.

When the photosensitive smoke detector of the smoke detector is roughly examined, the light emitted from the light source in the light transmitting portion reaches the lens of the opposing light receiving portion by making the parallel light beam by the lens. By the flow of smoke through the lens (parallel path) from the lens to the parallel light beam, the amount of light received from the light receiving element is reduced by an amount proportional to it, and the output is obtained by reaching the predetermined value. The detector is working.

There is this. In addition, when the smoke generator is used, there is a problem in that a smoke repellent such as a mosquito repellent is injected into the container of a certain size in order to generate smoke.

Therefore, the present invention was devised to solve the above problems, and an object of the present invention is to test the heat sensor or the smoke detector by operating the smoke generator and the heat generator as one switch, and the fire detector tester It is possible to use the fire detector tester without connecting to the power source installed in the building by applying a portable battery that can be charged in the building, and to provide a portable fire detector tester which can be used for a long time by injecting a single fuming agent into the smoke generator. have.
