DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a circuit diagram showing a fire receiver test apparatus RT1 according to one embodiment of the present invention.

[0009] The test apparatus RT1 of the fire receiver is an MPU1
A switch group including a plurality of switches SW1 to SW6, an LED group including a plurality of status lights LED1 to LED6, a display unit DP, an operation unit OP, a sensor power supply circuit 21, It has receiving circuits R1 to Rn, a smoke prevention equipment power supply circuit 22, and activation circuits DR1 to DRn.

The MPU 1 has a CPU (central processing unit) 10
RAM 11 for work, RAM 12 for fire test,
This is a one-chip microcomputer including a program ROM 13 and a switch I / F (not shown) for the switches SW1 to SW6. Note that a nonvolatile memory such as an EEPROM may be used instead of the backup RAM 12.

As the switches SW1 to SW6, a fire test switch SW1, a fire hydrant cutoff switch SW2,
An emergency broadcast interlocking switch SW3, a fire signal interception switch SW4, a smoke prevention interlock switch SW5, and a smoke prevention notification switch SW6 are provided.

As the status lights LED1 to LED6, a fire test status light LED1 and a hydrant cutoff status light LED2
An emergency broadcast interlocking state light LED3, a fire signal interception state light LED4, a smoke prevention interlocking state light LED5,
A smoke prevention smoke transfer cutoff state light LED6 is provided. Further, a heat sensor or a smoke sensor S is connected to the sensor lines L1 to Ln, and the smoke prevention smoke activation lines DR1 to DRn include:
A smoke prevention device such as a shutter is connected.

The work RAM 11 includes switches SW1 to SW1.
This is a first storage means for storing the state of the switch SW6. The fire test RAM 12 stores the switch SW1 during the fire test.
SW6, which is a non-volatile memory such as a RAM or an EEPROM that can be backed up. The ROM 13 is a memory for storing the program of the flowchart shown in FIG.

Next, a description will be given of smoke interception interlocking.

First, in the above embodiment, when the detector S connected to the line L1 detects a fire condition, the line L
Smoke prevention equipment T connected to the line D1 corresponding to
It is assumed that an interlocking relationship has been established so as to output a start signal.

Here, when the smoke prevention smoke cutoff switch SW5 is pressed, the smoke prevention smoke cutoff state light LED5 is turned on, and even if a fire signal is received from the detector S via the line L1, the interlocking relation with the line L1 is established. No activation signal is output from the activation circuit DR1 to the line D1 located at. As a result, the power supply to the smoke control device is cut off. As described above, it is possible to prevent the activation signal for activating smoke evacuating from being output to the line D1 which is interlocked with the line L1 (to prevent an external transmission signal from being sent outside the fire receiver). It is smoke exhaust interlocking.

Next, the operation of the test apparatus RT1 will be described.

FIG. 2 is a flowchart showing the operation of the test apparatus RT1.

First, the interruption state stored in the RAM 11 is read (S1). After this, fire test switch SW
1 is detected (S2), if the change is a change to turn on the fire test switch SW1 (S3), the cutoff switch SW2 is given priority to the cutoff state.
Out of the switches SW6 to SW6, other than the switch currently set to the cutoff state, is stored in RAM1.
The content is set to 2 (S4). That is, RAM1
When the cutoff switch is set to the cutoff state in either 1 or 12, the cutoff switch is set to the cutoff state. Then, a process for starting a fire test is executed (S
5) After that, unless the fire test switch SW1 is turned off, the fire test state is continued.

During the fire test, the fire test switch SW
When the switch 1 is turned off (S3), the state of each of the cutoff switches SW2 to SW6 is read out from the RAM 11, and according to the state of the read out switches SW2 to SW6, the controlled device corresponding to the switches SW2 to SW6 is read out. Is shut off (S11). That is, when the fire test switch SW1 is turned off during the fire test (S3), the RAM 11
When the state of each of the shut-off switches SW2 to SW6 is read out, a fire hydrant shut-off switch SW2, an emergency broadcast interlocking switch SW3, a fire signal shut-off switch SW4, an anti-smoke interlocking shut-off switch SW5, and an anti-smoke exhaust notification switch SW.
If it is determined that each of the blocks 6 is set to the cut-off state, a fire hydrant cut-off, an emergency broadcast interlocking cut-off, a fire signal shut-down, a smoke-prevention interlocking cut-off, and a smoke-prevention signaling interception are performed. Then, a fire test termination process is performed (S12).

On the other hand, after reading the interruption state stored in the RAM 11 (S1), the fire test switch SW1 is read.
State does not change (S2), the cutoff switches SW2 to SW
6, there is a cutoff switch whose state has changed (S2
1) If the cut-off switch that has changed state has changed from the off state to the on state (S31), the state of the cut-off switch that has changed to the on state, that is, the change of the cut-off switch to the on state, is stored in the RAM 11. (S32), the switch light of the cut-off switch changed to the ON state is turned on, the cut-off switch is set to the cut-off state (S33), and the process returns to step S2.

If any of the cut-off switches SW2 to SW6 has a changed state (S21), and if the changed state of the cut-off switch has changed from an on state to an off state (S31), the switch is turned off. The state of the cutoff switch that has changed to the state, that is, the change of the cutoff switch to the off state is stored in the RAM 11 (S3).
4) Turn off the switch light of the shut-off switch that has been turned off (S35), and if a fire test is being performed (S3).
6) The cutoff state of the cutoff switch is set to the content set in the RAM 12 (S37), and the process returns to step S2. If the fire test is not being performed, the cutoff is released according to the state of the cutoff switch (S38), and the process returns to step S2.

That is, when any one of the cutoff switches SW2 to SW6 is turned on from off, the change to on is stored in the RAM 11, and the corresponding switch light is turned on.
When any of the cutoff switches SW2 to SW6 is turned off from on, the change to off is stored in the RAM 11, and the corresponding switch light is turned off.

During the continuation of the fire test, when the smoke-prevention smoke interlocking switch SW5 is pressed again, the smoke-prevention interlocking cut-off light LED
5 is turned off, and the shutoff state of the smoke and smoke interlocking switch SW5 is set to the cutoff priority.
5 is maintained in the interrupted state. When the fire test is completed, the smoke-prevention and smoke interlocking switch SW5 is in the cut-off release state.

Similarly, when the smoke-and-smoke interlock switch SW5 is pressed again in the normal monitoring state, the smoke-and-smoke interlock switch LED5 is turned off and the smoke-and-smoke interlock switch SW5 is turned off.
Is in the cutoff release state.

The setting of the shut-off state of each shut-off switch of the RAM 12 at the time of a fire test is performed using a nonvolatile memory such as an EEPROM in which the set contents are stored in advance. When a RAM that can be backed up is used, a preset shut-off state setting mode is set so that even if various switches in the fire receiver are operated, the shut-off state cannot be easily set from the panel of the fire receiver. Switch for setting the switch to select the cutoff switch,
The cutoff state of the cutoff switch can be set by operating a switch or the like for specifying the release of the cutoff, and the contents thereof are stored in the RAM 12. This setting
This has no effect on the normal interlocking.

In the above embodiment, when the fire test switch SW1 is pressed to turn on the fire test status light and the fire test state is entered, the smoke prevention interlocking operation stored in the RAM 12 is effective only during the fire test. In order to distinguish from the interruption by the RAM 11 in the normal monitoring state, the smoke emission prevention state lamp is not turned on, but the smoke emission prevention state is set in the internal state.

Therefore, when the line L1 is fire-tested,
Since the line L1 is in the same state as at the time of a fire, an activation signal should be output to the line D1 which is interlocked with the line L1. However, since the line D1 is in a cutoff state, No start signal is output to the line D1. Also,
Even if the smoke prevention switch SW5 is operated during the fire test,
The state in which the lines D1 to Dn relating to the smoke prevention equipment are cut off is not released. However, smoke and smoke prevention switch SW5
The state of the shutoff / release state and the state of the smoke-discharge interlocking shut-off state lamp operated at the time of the fire test is reflected at the end of the fire test. In this case, even if the fire test is terminated, the smoke-prevention smoke interlocking cutoff state is continued.

FIG. 3 is an explanatory diagram of the operation in another embodiment of the present invention.

At the time of initial setting (at the start) a,
The content stored in the RAM 11 is the cutoff switch SW2
To SW6. Then, when the state of the cutoff switches SW2 to SW6 is changed immediately before the fire test b, the changed contents are stored in the RAM 11. In the example shown in FIG. 3, the emergency broadcast interlocking switch SW3 and the smoke-prevention / smoke prevention notification switch SW6 are changed to "blocking".

When the fire test switch SW1 is turned on (at the time of the fire test c), immediately before the fire test b, the line for the terminal device corresponding to the cut-off switch set to the cut-off state maintains the cut-off state of the output signal of the start signal. Then, the lines for the terminal devices corresponding to the other cutoff switches are in the same state as the state stored in the RAM 12. Immediately before the fire test, the cutoff switch lamp of the cutoff switch corresponding to the terminal device line set to the cutoff state is turned on, and the cutoff switch light corresponding to the terminal device line cut off by the contents of the RAM 12 at the time of the fire test. The cutoff switch light turns off.

When the state of the cutoff switch is changed during the fire test d, the change is stored in the RAM 11. In the example shown in FIG. 3, the fire signal cutoff switch S
W4 is changed to “interruption”, and the smoke prevention smoke alarm information
W6 has been changed to "block release". If the cutoff switch that has been released is changed to cutoff during the fire test, the cutoff switch is turned on and the cutoff switch is turned on. In addition, when the shut-off switch that was shut off during the fire test is released, the shut-off switch that was shut off during the fire test maintains the shut-off state, the shut-off switch goes out, and the shut-off switch that was released during the fire test turns off the shut-off switch. The state is released and the cutoff switch goes out.

At the end e of the fire test, the RAM 11
Is stored in the state of each cutoff switch.

According to the above embodiment, in the fire test,
A test is performed in which a line linked to a controlled device such as a smoke prevention device is set to a fire state. During this test, the controlled device is not activated even if the cutoff switch is erroneously operated. Further, if the shut-off switch is operated during the test, the operation is reflected at the end of the test, so that useless operation can be eliminated.

The above embodiment is a test apparatus for a fire receiver in which a fire test switch is operated to shift a fire receiver to a test state.
2 to SW6 are examples of cutoff switches that cut off the output of an external transmission signal transmitted to the outside of the fire receiver.

The activation signals output from the activation circuits DR1 to DRn are examples of external transmission signals transmitted to the outside of the fire receiver. That is, the external transmission signals include a smoke control signal, a fire signal, The signal is at least one of a smoke control signal and an emergency broadcast interlocking signal. The RAM 11 is an example of a first storage unit that stores the state of the cutoff switch, and the RAM 12 is a second storage unit that stores the state of the cutoff switch in a fire test.

Further, the MPU 1 operates the fire test switch to read out the state of the cutoff switch from the second storage means and stores it in the first storage means or the second storage means. If any of the states of the shut-off switch is in the shut-off state, the output of the external transmission signal of the shut-off switch is shut off, and when the operation of the fire test switch is released, the state of the shut-off switch is changed to the second state. 1 is another example of the external transmission signal blocking unit that reads out from the first storage unit and executes blocking or release of the output of the external transmission signal in accordance with the read state of the blocking switch.

Next, the operation of the test apparatus RT1 will be described based on the operation explanatory diagram of each cutoff switch shown in FIG.

The interruption state lamp is turned off (S35). Further, in this case, since the fire test is not being performed (S36), the cutoff switch is set to the cutoff release state (S38), and the process returns to step S2.

Turns off.

After this state, the fire test switch SW1
Is turned on, it is detected that the state of the fire test switch SW1 has changed (S2), and since the change is a change for turning on the fire test switch SW1 (S3), the cutoff state is prioritized. Therefore, the cutoff switch SW2
Out of the switches SW6 to SW6, other than the switch currently set to the cutoff state, is stored in RAM1.
The content is set to 2 (S4). That is, RAM1
If the cutoff switch is set to the cutoff state in either the RAM 1 or the RAM 12, the cutoff switch is set to the cutoff state. Then, a process of starting a fire test is executed (S5), and thereafter, a fire test switch SW1 is executed.

Is in the cut-off state according to the contents stored in the smoke prevention / smoke prevention interlock switch S.
W5 is newly turned off. Note that the cut-off state light of the smoke prevention and smoke interlocking cut-off switch SW5 is cut off by the RAM 12, so that the cut-off state light remains off.

Next, the case where the state of the cutoff switch is changed during the fire test will be described.
