Description

[Detailed description of the invention] Technical field This invention relates to a device for testing the function of smoke prevention equipment such as smoke exhaust vents and fire doors.

Conventional technology Conventionally, when performing a functional test of smoke prevention equipment that is controlled in conjunction with the operation of a fire detector, etc., the operator at the control panel starts and restores the remote switching device of the smoke prevention equipment. They sent signals and visually checked the operation and recovery of the smoke control equipment by other staff on site.

Problems with the Prior Art However, this method has the disadvantage that it requires a lot of labor and time when testing a large number of smoke control devices.

Measures to Solve the Problems In view of the above-mentioned drawbacks, this invention makes it possible to test the operation of smoke control equipment and check its operation simply by operating the test switch on the central control panel. and, corresponding to each smoke prevention device, a first relay that operates by the operation of a relay that restores the preceding smoke prevention device or the closing of a push button switch to operate its own smoke prevention device; a second relay that operates according to the operation of the smoke prevention equipment; and a third relay that restores the smoke prevention equipment by the operation of the second relay; The smoke prevention equipment is characterized in that its operation is maintained through the contacts, and a lamp is provided to indicate that the smoke prevention equipment has been activated and is operating normally.

Operation When the test switch and starting pushbutton switch are pressed, the first relay operates and the solenoid for opening the smoke exhaust port is energized. Also, when the smoke exhaust port is opened, this is detected by closing the limit switch, etc., and the second
The first relay is activated and the first relay is restored. When the contacts of the second relay are closed, the third relay operates, and the contacts operate a solenoid for restoring the smoke outlet. When the smoke exhaust port is restored to normal and is closed again, the second and third relays are restored, and whether or not they are operating normally can be determined by the lighting state of the lamp lit by the second relay.

Embodiment An embodiment of this invention will be described below with reference to the drawings. In the figure, Re is a control panel installed in a building's disaster prevention center, etc., _l1 is the positive power line connected to the positive terminal of power supply _E1 via test switch S,

This is a solenoid for restoring the opening/closing device that closes the smoke exhaust port by inverting it.

Furthermore, the above control panel Re has the above smoke exhaust port X ₁ ,

will be provided.

The first relay N is the first control test circuit.
In Y ₁ , push button switch P for starting,
In the second and subsequent control test circuits Y ₂ , Y ₃ . _. . , _the make contacts t ₁₁ ,
t ₂₁ ... is connected between the power lines l ₁ and l, and the normally closed side of the relay contact D and the switching contact m ₁ of the relay M operated by the push button switch P ₁ and a fire detector (not shown) and the self holding contact

It is connected between l ₂ and l. Also, the make contact n ₂ of the relay N is connected between the power lines l ₃ and l via the starting solenoids ER of the corresponding smoke exhaust ports X ₁ , X ₂ , X ₃ .

The second relay M is connected between the power lines l ₂ and l via a limit switch LS that is closed when the smoke exhaust port is opened.

In addition, the third relays T ₁ , T ₂ , T ₃ ... are relays M
It is connected between the power supply lines l _{1 and} l through the make contact m 2 of the switch P ₂ and the self-holding contacts t ₁₃ , t ₂₃ , t ₃₃ as necessary.
and the make contact m ₃ of the relay M are connected between the power lines l ₂ and l through a series circuit. Also, relay T ₁ ,
The make contacts t ₁₂ , t ₂₂ , t ₃₂ ... of T ₂ , T ₃ ... are the recovery solenoids of the corresponding smoke exhaust ports X ₁ , X ₂ , X ₃ ...
It is connected between power lines l ₃ and l via ER'.

Furthermore, L ₁ and L ₂ are lamps that indicate the activation and completion of operation of the smoke exhaust port, respectively, and the lamp L ₁ is connected to the normally closed side of the switching contact m ₁ of the relay M and the make contact n ₁ of the relay N. The lamp L ₂ is connected between the power lines l ₂ and l through the normally closed side of the switching contact m ₁ .

Next, the operation of the above test device will be explained. For example _, when _a fire detector installed at smoke exhaust _port
The solenoid ER for starting X ₂ is energized and the smoke exhaust port X ₂ is energized.
is opened and smoke is exhausted outside. Also, this opening operation closes the limit switch LS and operates the relay M, so its contact _m1 switches and the lamp lighting shifts from _L1 to _L2 , so the control panel Re
It can be confirmed that smoke exhaust port X ₂ was operating normally.

When conducting a test, close the test switch S and press the activation push button switch P of the first control test circuit _Y1 , and the relay N will operate in the same way as when a fire detector operates. The solenoid ER of smoke outlet X ₁ was energized to open smoke exhaust outlet X ₁ , contact n ₁ was closed, lamp L ₁ was turned on, and relay N to operate smoke outlet X ₁ was activated. This will be displayed. Furthermore, when the smoke exhaust port _X1 is opened, the limit switch LS closes and the relay M operates, so the contact _m1 switches and the lamp _L2 lights up, indicating that the smoke exhaust port _X1 has been opened normally. At the same time, relay N is restored. Further contacts
When m ₂ is closed, relay T ₁ operates, and its operation is maintained by closing contact t ₁₃ and contact m ₃ , and when contact t ₁₂ is closed, the recovery solenoid ER of smoke exhaust port X ₁ is energized. and by closing contact t ₁₁ , the second
The relay N of the th control test circuit _Y2 operates and its operation is maintained by closing its make contact _n1 . After such an operation, the smoke exhaust port _X1 is restored and closed again, so that the limit switch LS is opened and the relays M and _T1 are restored. On the other hand, the relay N of the control test circuit Y ₂ , which is already in operation, energizes the solenoid ER of the smoke exhaust port X ₂ by closing its make contact n ₂ , as in the case of the first smoke exhaust port X ₁ . The test is continued to the third smoke outlet X ₃ .

In such a state, if the second smoke exhaust port _X2 does not operate due to a failure, for example, the limit switch LS remains open and the relay M does not operate, so the lamp _L1 continues to be lit, indicating that there is a failure. In this case, you can either press push button switch P ₂ to operate relay T ₂ and operate relay N of control test circuit Y ₃ through contact t ₂₁ , or operate it directly with push button switch P ₁ to activate the The test for Smoke Mouth X ₃ can be resumed. In addition, if smoke exhaust port X ₂ cannot be restored due to a failure, the relay
Since T ₂ operates, _{the subsequent} smoke exhaust ports _{X 3 .} Even after completion, the lamp L ₂ of the smoke exhaust port X ₂ continues to be lit, confirming that there is a malfunction.

Effects Since the testing device of this invention is configured and operates as described above, it is possible to test the smoke prevention equipment from the control panel side, and also to confirm whether or not the operation is performed normally. There is an effect that can be obtained.
