Next, the operation of the above embodiment will be explained.

Currently, as shown in Fig. 1, a security guard 17 is away from the central monitoring room where the receiver 1 is installed and is making regular night patrols. Suppose a fire breaks out in the dining room on the 12th floor. When a fire occurs in the dining room on the 12th floor, the smoke detector 13 is activated and sends a fire detection signal to the receiver 1, and the controller 6 of the receiver 1
receives a fire detection signal from the smoke detector 13 via the input/output unit 5, displays a fire alarm and the location of the fire on the display unit 2, and at the same time sounds a ringing unit such as a bell to detect the fire. Issue a warning.

At the same time as this fire alarm reception operation, the control section 6 starts the superimposition control section 8, gives the fire information displayed on the display section 2 to the superposition control section 8, and creates a fire information code with the superposition control section 8. A predetermined carrier frequency is modulated and superimposed on the transmission line 10 via the capacitor C. Fire information is transmitted by radio waves to the warning area using the transmission line 10 as a transmission line antenna.

Therefore, the security guard 17 patrolling the fourth floor receives fire information from the superimposition control section 8 of the receiver 1 using the portable receiver 16, and displays a fire alarm as shown in FIG. 3, for example. The light 26 lights up to notify that a fire has occurred, and the indicator 29
The display 30 displays that the fire occurred on the "12th floor" and that the fire occurred on the "101" line, and that the fire occurred on the "dining room".

Therefore, the security guard 17 does not return to the receiver 1 installed in the central monitoring room on the first floor or basement, but immediately rushes to the cafeteria on the 12th floor, where the fire occurred, to confirm the fire and perform initial extinguishing. Furthermore, it is possible to quickly take measures such as reporting to an external organization.

In addition, if you rush to the scene of the fire according to the display on the portable receiver 16 and it is confirmed that the alarm is due to a false alarm from the detector, the portable receiver 16 shown in FIG. When the recovery switch 32 is operated, a recovery control signal is transmitted by radio waves from the portable receiver 16, and is sent to the superposition control section 8 of the receiver 1 with superimposition transmission on the transmission line 10, and the superposition control section 8 performs recovery. By decoding the reception of the signal and activating the switching means connected in parallel to the recovery switch 9 of the operation section 7, the control section 6 can be restored by the same process as when the recovery switch 9 of the operation section is operated. The security guard 17 can restore the reception 4g11 using the portable reception 11116 without returning to the installation location of the receiver 1.

Note that the above embodiment includes the receiver 1 and the security guard's portable receiver 1.
This example uses a superimposed transmission method that uses a transmission line as an antenna to transmit and receive radio waves between
The present invention is not limited to this, but direct wireless communication may be performed between the receiver 1 in the central monitoring room and the portable receiver 16 held by the guard.

In addition, as the portable receiver used in the present invention shown in FIGS. 2 and 3, portable radio wave ICs that have been put into practical use in recent years are used.
Of course, cards may also be used. Furthermore, a sounding mechanism such as a buzzer may be added to the portable receiver so that when an abnormal situation occurs, the sounding operation is performed to notify a security guard of the abnormality.

[Effects of the Invention] As explained above, according to the present invention, when an abnormal alarm such as fire, theft, gas leak, etc. is issued by the receiver of the alarm equipment during a regular patrol such as at night, the security guard Since abnormality information, including at least the location of the abnormality, is transmitted from the receiver and can be displayed on the portable receiver that the user has, the user can immediately rush to the site of the abnormality and take immediate action without having to return to the location where the alarm equipment's receiver is installed. can do.

In addition, as a unique effect of this embodiment, a recovery switch is installed on the portable receiver to enable the receiver of the alarm equipment to be recovered remotely, so even in the event of a false alarm, the user can return to the receiver installation location and carry out recovery operations. This provides the convenience of not having to do this.
