BACKGROUND OF THE INVENTION
The present invention relates to a security system that reports to a security center via a communication line such as a telephone line when a fire occurrence or an intruder is detected in the security area, and in particular, the security area of the security system is alerted from a released state by a radio signal. The present invention relates to a device capable of reducing battery consumption of a wireless security set operation device that performs a set operation in a set state (set state) and confirms whether or not a controller is in a set state.
[0002]
[Prior art]
In the above security system, various sensors such as fire detectors, intruder detectors, gas leak detectors, etc. are installed in the security areas of condominiums, ordinary houses, buildings, factories, etc., and these sensors are connected to the controller. Yes. The controller is connected to a remote security center via a telephone line. For example, when the intruder detector detects an intruder when the security area is in the set state, an intrusion abnormality signal is reported from the controller to the security center, and appropriate measures are taken, such as a countermeasure person from the security center. It has to. On the other hand, people in that when the guard area is in the release state Ri Contact performing normal activities, intruder detectors also detect an intruder, not Problem intrusion alarm signal to the security center from the controller.
[0003]
In the security system, for example, a security mode setting device that switches the inside of the security area from the released state to the set state or from the set state to the released state is provided outside the security area. In this case, when the inside of the security area is unmanned, the user confirms that all sensors except the final exit are in a warning state with the controller in the security area, and ensures that the door of the final exit etc. After closing, the inside of the security area is set to the set state by the outer security mode setting device. In some cases, a security mode setting device is built in or near the controller. In this case, when a setting operation for setting the set state is performed by the security mode setting device in the security area, a delay timer (for example, 2 minutes) is activated and the security system is in a set preparation state. When the security system is in the set ready state, it will be in the set state after the delay time elapses, but if the user goes out of the door, that is, out of the security area and leaves that position before the delay time elapses, and There is a problem that an unwarranted blank time occurs in the release state.
[0004]
[Problems to be solved by the invention]
In the above security mode setting device, the electrical connection with the controller is wired, wiring work is costly, and the wiring and through holes of the wiring impair the aesthetic appearance of the wiring. There is a problem that is disconnected.

Become frequent. Further, the inside of the security area is shifted from the released state to the set state only several times a day. If the security set operating device is always in an active state for this operation, the battery is consumed significantly.
[0005]
Therefore, in view of the above problems, an object of the present invention is to provide a wireless security set operating device that can reduce power consumption.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, the present invention is a wireless security set operation for transmitting a signal requesting a transition to a warning set state to a controller that sets a security area to a warning set state or a release state. In the apparatus, a set operation unit that performs a set request operation for shifting from the release state to the alert set state, a transmission unit that wirelessly transmits a set request signal to the controller, and a set request confirmation signal from the controller is wirelessly received. It becomes an active state based on a set request operation of the receiving unit and the set operation unit, transmits a set request signal to the controller via the transmission unit, and then receives a set request confirmation signal to sleep from the active state And a security set operating device provided with a control unit for switching to.

As shown in FIG. 4 (see FIG. 5), in step S1, the apparatus waits in the sleep state until the set button 64A is pressed. If pressed in step S1, in step S2, the power supply unit 59A wakes up the wireless security set operating device 6A to make it active, and outputs a set request via the transmitting unit 62A and the antenna 61A to output the timer 68A. Start. Then, at a predetermined interval, in step S3, it is determined whether or not a set request confirmation signal (set OK) is returned from the controller 5A via the antenna 61A and the receiving unit 63A. If there is a reply in step S4, the display unit 67A is caused to blink the set OK. After a predetermined time has elapsed, in step S5, the wireless security set operating device 6A is set to the sleep state, and the process returns to step S1. If there is no set request confirmation signal while the timer 68A is timing in step S3, it is determined in step S6 whether or not the controller 5A has received a signal indicating that the controller 5A is not in a set ready state (set NG). When the set NG signal has been received, the display unit 67A is caused to blink the set NG in step S7, and the process proceeds to step S5 after a predetermined time has elapsed. If a signal that cannot be set is not received in step S6, it is determined in step S8 whether the timer 68A has expired at the preset time. If it is before the time is up, the process returns to step S3, and if the time is up, the process proceeds to step S7.
