PORTABLE CHECKER FOR FIRE DETECTING SYSTEM}

The present invention relates to a circuit checker of a fire detection system applied to a ship, and more particularly, when the main body of the fire detector is detached and mounted on the fire detector base instead of the fire detector main body is automatically connected to the cable connection terminals of the base. It is a portable fire detector circuit checker that can check cable incorrect wiring, cable normal wiring disconnection, terminal block defect and reverse voltage occurrence based on the operation of LED lamp and buzzer connected.

In general, a large number of fire detectors are installed in ships and fire detectors are connected to the fire detector main system. These fire detectors are connected to the main system by distinguishing the positive (+) (-) (secondary) line, and it is necessary to check whether the fire detector is installed normally.

1 is a photograph of a conventional fire detector cable inspection. As shown in the related art, there are two methods for inspecting a fire detector cable. The method is mainly used.

As shown in (a) of FIG. 1, one inspection person should wait for the check of the line connected to each fire detector while waiting on the main panel, and another inspection person, one local person, needs to check The fire detector must be disconnected from the installation location and contacted with inspection equipment at the base to test the cable break, cable miswiring or miswiring.

As such, the cable checks on the walls, ceilings, cable trays, etc. should be checked using an electrical meter in pairs of two.

FIG. 2 is a photographic view illustrating a problem of a conventional fire detector inspection, as shown in FIG. 2A. The visual inspection is performed as shown in FIG. 2A, and the local inspector separates the main body of the fire detector. The wiring of the wire connected to the fire detector base must be checked visually. Incorrect wiring or short circuit of the cable should be checked with a tester. In addition, as shown in (b) of FIG. 2, the fire detector installed in the ceiling or the aerial area has a risk of heightening work because the local inspector must directly approach the corresponding location to perform visual inspection and inspection using a tester.

In addition, repeated corrections occur due to an error occurring during visual inspection of the fire detector wiring.

In addition, since at least 120 fire detectors are installed in a ship, it takes a long time to check a plurality of fire detector cables, and it is impossible to pre-check the fire detector itself such as a fire detector base or a cable terminal block. Used inspection requires a lot of working period and there was a problem of inherent risk of safety accident.

The present invention is simply installed in the fire detector base instead of the main body of the fire detector in view of the problems of the conventional fire detector inspection so that it can check the normal, erroneous wiring, cable disconnection and base or terminal block defect and reverse voltage generation One portable fire detector is to provide a circuit checker.

The present invention enables to check the normal and erroneous state by displaying the LED lamp lights, and if the cable installation is reversed voltage is changed so that the buzzer sounds so that the connection between the cable installation and the fire detector can be accurately determined. One portable fire detector is to provide a circuit checker.

FIG. 5 is a photographic view of a circuit checker for inspecting a fire detector according to the present invention, and FIG. 6 is a battery installation for checking a fire detector according to the present invention, and a circuit checker check state of a circuit checker installation and inspection personnel. The picture is shown.

As shown therein,

Two lines L1 (+) and L (-) drawn out from the fire detector main panel 10 are wired as fire detector cables, and a fire detector 20 is connected to the cables of the two lines at each position. The fire detector 20 is provided with terminals L1 (+), L (-) and auxiliary terminals L2 installed in an open state to which the cables of the two lines are connected, and the fire detector base 21 fixed to a ceiling or a wall, etc. And the lower cover 22 to be detachably installed at the base 21 and to connect the cable connection terminals L1 (+) and L (-) of the two lines with the connection terminals of the sensing circuit unit 24 therein. It is configured, the fire detection sensor unit 25 is installed is composed of an upper cover 23 coupled to the upper portion of the lower cover 22. Here, the auxiliary terminal L2 of the general fire detector is provided in an open state.

The present invention has the same structure as the fire detector lower cover 22 attached to and detached from the base 21 of the fire detector 20 configured as described above, and is attached to and detached from the fire detector base 21 and the fire detector base 21. 3 terminal blocks (L1 (+), L (-), L2 (auxiliary)) that are electrically connected to the three connection terminals (L1 (+), L (-), L2 (auxiliary)) Lower cover 101 is provided;

A first lamp 103 connected to L1 (+) and L (-) of the three terminal blocks of the circuit checker lower cover 101;

A second lamp 104 connected to L1 (+) and L2 (sub) of the three terminal blocks of the lower cover 101;

A buzzer 105 which is connected to sound a buzzer when a current flow occurs in the L1 (+) direction among the three terminal blocks of the lower cover 101;

An upper portion accommodating the buzzer 105 between the lower cover 101 and the first and second lamps 103 and 104 are exposed to the outside and coupled to the upper portion of the lower cover 101. It is composed of a cover 102. Here, reference numerals L1 (+), L (-), and L2 of the connection terminals of the fire detector base 21 and the terminal blocks L1 (+), L (-), and L2 of the lower cover are the same as for convenience. Display.

In addition, the present invention is configured to supply a test power to the circuit checker 100 by mounting the battery 110 as an auxiliary power supply to the fire detector main panel (10).

In addition, the first lamp 103 and the second lamp 104 is characterized in that using the LED lamp of different colors.

The portable circuit checker according to the present invention configured as described above, as shown in FIG. 3, detaches the main body from the existing fire detector 20, and the circuit checker 100 according to the present invention to the fire detector base 21. 6, the inspection preparation is completed by mounting the battery 110 as the inspection power to the main panel 10 to supply the inspection power as shown in FIG. 6 (a). That is, the main panel 10 is installed so that the battery power is supplied only to the cable connected to the fire detector without power supply.

As shown in (b) of FIG. 6, when the circuit checker 100 is installed in place of the main body of the existing fire detector 20 at the position to be checked, the installation state of the existing fire detector is the same. According to the lighting state of the circuit checker 100 as a state, as shown in (c) of FIG. 6, the inspector can visually determine the state of the cable connection by checking whether the lamp is lit or the buzzer sounds. That is, in the state where only the fire detector base 21 is installed by removing the lower cover 22 of the fire detector 20, the circuit checker 100 according to the present invention is mounted on the fire detector base 21. Accordingly, the three connection terminals installed on the fire detector base 21 and the three connection terminal blocks installed on the lower cover 101 of the circuit checker 100 are electrically connected to each other.

In this way, if the circuit checker 100 is mounted after removing the main body of the upper and lower cover while leaving the base 21 of the fire detector 20, the energization and cable connection state (the connection state of the cable and the fire detector base connection terminal) In accordance with the circuit checker 100 is operated.

When the first lamp 103 (eg, green lamp) of the circuit checker 100 is turned on, it indicates that the cable connection state is normal. This is because the first lamp 103 is turned on only in the normal connection where current flows from the L1 (+) side to the L (-) side, and when the first lamp 103 is turned on, the cable connection is normal.

If the second lamp 104 is turned on, the terminal that should be connected to the L (−) line is connected to the L2 (secondary) line, indicating a miswiring state. That is, when the current flows from the L1 (+) side to the L (secondary) side, the second lamp 104 is turned on, and the first lamp 103 is turned off to determine that it is a miswiring state.

On the other hand, when the L1 (+) line and the L (-) line to be connected to each other, the buzzer sounds as the current flows through the buzzer 105. That is, the current flow is generated from the L (-) line to the L 1 (+) line, which is a (+) (-) change, at which time the buzzer 105 rings.

Therefore, in the present invention, it is possible to check the cable at the fire detection system when the single person checks the cable, it is possible to determine whether there is a cable abnormality without the electric measuring device when checking the cable, the cable connection status check and the wiring of the sensor base is not a visual check It can be checked by the checker, and the inspection time of a large number of fire detectors can be shortened by the simplicity and simplification of the fire detector inspection, and it has the effect of reducing the time for working at high places and preventing accidents.

On the other hand, Figure 3b is a line isolator base fire detector inspection system diagram using a circuit checker according to the present invention, which is a fire to separate the group in the case of installing a large number of fire detectors connected in parallel due to the characteristics of the fire detector 20 The base 21 'of the detector is provided with connection terminals L1 (+), L (secondary), L2 (OUT), and M (IN). This is to separate and manage the connected fire detectors in front of the fire detector using the line isolator base 21 'and the fire detectors connected to the rear, and the internal fire detector circuit is configured for the corresponding base terminal.

Even when the isolator base 21 'is equipped with a fire detector, when the circuit checker 100 of the present invention is mounted as it is, the input connector M (IN) to the output connector L2 (OUT) in the normal state. When the normal energization is made, the second lamp 104 is lit to indicate that it is in a normal state. If the first lamp 103 is turned on, it means an erroneous wiring, and the buzzer sounds when the reverse voltage (wrong wiring) is applied to notify the reverse voltage erroneous wiring.

Therefore, even in the case of a fire detector using the isolator base (21 ') is applied to check the circuit checker 100 of the present invention as it is, but only the lamp that is turned on in the normal state and the wrong wiring state is changed, which Since the isolator fire detector and the general fire detector are structurally distinguished, the inspector can easily recognize them, and in the isolator base fire detector, the normality can be determined according to the type of lighting lamp of the circuit checker. Thus, the present invention can use the same circuit checker even if the type of the base of the fire detector is different.
