Description

The present invention relates to a detector test system for a fire alarm system that tests a fire detector using a test jig.

Conventionally, in the case of fire alarm equipment, periodic inspections are performed during the operation of the equipment, and in that, a detector test for actually operating the fire detector is performed using a test jig.

The sensor test is conducted by two testers, one on the receiver and one on the sensor side. The examiner on the sensor side uses a test jig provided with a test head at the tip of the support pole, and the test head is brought into close contact from below so as to cover the smoke detector, for example, and smoke flows in from the test head in this state. Let the smoke detector operate, or operate the smoke detector in a simulated manner by operating a reed switch with a magnet, and the examiner of the receiver confirms whether or not there is a fire reception accompanying the operation test of the fire detector. , We are proceeding with the test work while contacting by intercom.

As described above, the sensor test requires at least two testers, and a sensor test system capable of performing this by one person is expected for the purpose of reducing the work man-hours. For example, a printer that detects fire reception and launches it as a test result is installed in the receiver, an operation test of the fire detector installed in the caution area is performed using a test jig, and when the detector test is completed, the printer It is a detector test system that judges whether the fire detector that has been tested for operation is normal or abnormal by looking at the recorded contents.

In such a detector test by one examiner, since the examiner is not attached to the receiver side and the fire alarm recovery operation from the receiver cannot be performed in connection with the detector test, for example, prior to the detector test, for example. For the district acoustic alarm, perform the alarm stop operation, and for the main acoustic alarm issued from the receiver, set the alarm to be output only while the fire detection signal is being received, regardless of the restoration operation. Will do.

However, in such a conventional detector test system that enables a detector test by one examiner, an operation test of a fire detector installed in a caution area by the examiner using a test jig is performed. In the case of, the sensor issued a test alarm and it was received normally by the receiver, but it is not known unless you return to the receiver and look at the recorded contents of the printer, so two examiners contacted by intercom. Compared to the test conducted while doing the test, I was worried because I could not grasp the situation on the receiver side in real time, and when the work progressed to some extent, I returned to the receiver and performed while checking the test result, so the work burden There is a problem of increasing.

Also, if a fire actually occurs during the sensor test work, a fire alarm is output from the receiver, but it is possible to distinguish whether this fire alarm is due to the detector test or the actual fire. In some cases, it is difficult to get a fire and it is difficult to hear the alarm sound from the receiver, and it takes time to notice the fire, which may make it impossible to take prompt and appropriate measures.

In addition, if the examiner learns of a fire during the detector test work, it is necessary to return to the receiver to output the district acoustic disaster alarm, and it takes time for the district acoustic alarm to be output. be.

The present invention provides a detector test system for a fire alarm system, which enables the operation of the receiver side to be confirmed even in the test work by one examiner and enables the test work of the sensor to proceed without anxiety. With the goal.

The present invention relates to a detector test system for a fire alarm system.
With a fire detector,
The receiver that connects to the fire detector and
With mobile terminals
Equipped with
When the mobile terminal receives a signal based on the fire detector's alarm during the fire detector test, it notifies the predetermined test alarm by the detector test, and after receiving the signal, the relevant item. Is received again, it is characterized in that a fire alarm is notified.

When the test of the fire detector is performed by a plurality of detectors, the mobile terminal does not notify the fire alarm even if the signal is received again after receiving the signal based on the alarm of the fire detector.

After receiving the signal based on the alarm of the fire detector, the mobile terminal can select whether to notify the fire alarm when the signal is received again.

(Basic effect)
The detector test system of the fire alarm equipment according to the present invention is a telephone line adapter connected between an input / output port provided in the control unit of a receiver and a telephone line to transmit a signal from at least the input / output port to the telephone line. A wireless line adapter that is detachably connected to the telephone connection terminal of the transmitter and at least converts the signal received from the telephone line adapter into a wireless signal and transmits it, and receives and processes the wireless signal from the wireless line adapter. A mobile terminal is provided, and the control unit of the receiver receives a fire signal from the fire detector in the set state of the detector test mode including a predetermined acoustic stop alarm, and the test alarm signal addressed to the mobile terminal. Is output to the input / output port and transmitted to the mobile terminal via the telephone line adapter and the wireless line adapter, and the control unit of the mobile terminal is from the control unit of the receiver via the telephone line adapter and the wireless line adapter. When the test issuance signal is received, the test issuance by the detector test is notified. Therefore, when one examiner performs the detector test work using the test jig, the fire detector is tested. When the fire signal is received, the test alarm signal is transmitted from the receiver, and the test alarm is displayed and acoustically notified from the mobile terminal such as a smartphone owned by the examiner to test the fire detector. By knowing in real time that the fire reception by the alarm was performed normally and knowing the operation of the receiver, even one examiner can proceed with the test work without anxiety, and the work is in progress. It is not necessary to return to the receiver and check the printer launch, etc., which makes it possible to significantly reduce the work load.

In addition, when performing sensor test work, by connecting the wireless line adapter prepared as a portable test device to the telephone connection terminal (telephone jack) of the transmitter installed in the monitoring area where the test work is performed, It is possible to form a wireless communication area that can communicate with a mobile terminal centering on the installation location of the transmitter by communicating with the telephone line adapter built into the receiver via the telephone line, and equipped with a telephone jack. Since the transmitter is always installed in each warning area divided by floor, for example, a wireless communication area that can communicate with the mobile terminal is surely formed in the warning area where the sensor test is performed, and a place away from the receiver. Even so, the test report can be reliably transmitted to the mobile terminal owned by the examiner to be notified.

(Effect of notification of recovery of test notification)
In addition, the control unit of the receiver receives the fire signal from the fire detector, transmits the test alarm signal, and then when the reception of the fire signal from the fire detector stops, the test is directed to the mobile terminal. The alarm recovery signal is output to the input / output port and transmitted to the mobile terminal via the telephone line adapter and wireless line adapter, and the control unit of the mobile terminal is the receiver's via the telephone line adapter and wireless line adapter. When the test signal recovery signal from the control unit is received, the test report recovery due to the end of the sensor test is notified, so the examiner uses the test jig to perform the test report test of the fire detector. After confirming the operation of the receiver by the notification of the mobile terminal, when the test jig is removed and the fire detector is restored, the mobile terminal can confirm the recovery of the test report on the receiver side, and the detector test. By understanding the operation of the receiver in more detail, it is possible to proceed with the test work with peace of mind.

(Effect of fire alarm)
Further, if the control unit of the mobile terminal receives the test alarm signal from the receiver control unit via the telephone line adapter and the wireless line adapter and then receives the test alarm signal again, it is determined to be a fire. Because the fire alarm is output, the test is not issued twice in a row in the test work by one examiner, so it is judged as a fire when the second test is received by the mobile terminal. By notifying the fire alarm, it is possible to reliably know the fire that occurred during the test work by one examiner and deal with it promptly and appropriately.

(Effect of automatic cancellation of maintenance / inspection mode based on fire judgment)
In addition, the control unit of the receiver is set to stop the district acoustic alarm in the set state of the detector test mode and output the main acoustic alarm while receiving the fire signal, and controls the mobile terminal. When a fire is determined, the unit outputs a fire alarm and sends a signal to indicate the release of the sensor test mode addressed to the receiver, cancels the sensor test mode of the receiver, and switches to the fire monitoring mode. Therefore, the detector test mode of the receiver is automatically canceled by the instruction from the mobile terminal, and the fire alarm (main acoustic alarm and district) is received by receiving the fire detection signal based on the actual fire, as in the case of normal monitoring. It is possible to output an acoustic alarm), and it is possible to quickly and appropriately deal with a fire that occurred during the sensor test.

(Effect of notification of line number or sensor address)
In addition, when multiple wireless line adapters are connected to telephone connection terminals provided in multiple transmitters and multiple mobile phone terminals receive and process wireless signals from each wireless line adapter, the control unit of the receiver is , The test issuance signal and the test issuance recovery signal of the broadcast addressed to all mobile terminals are transmitted including the line number or sensor address where the fire signal was received, and the control unit of the mobile terminal sends the test issuance. When a signal or test issuance recovery signal is received, the line number or sensor address is notified from the test issuance or test recovery by the sensor test, so that, for example, multiple monitoring areas with different lines, for example, different floors. Even if multiple testers perform the test of the fire detector installed in the same time in parallel, the receiver operation by the test report of the fire detector that I tested from the line number displayed on the mobile terminal can be operated. It is possible to know and enable simultaneous detector test work by multiple examiners, greatly shortening the work time required for the detector test of the fire alarm equipment installed in a large-scale facility and improving work efficiency. Is possible. In this case, a fire alarm based on the re-receipt of the test alarm signal by the mobile phone terminal is prohibited.
