In addition, people involved in fire prevention objects who carry mobile phone terminals 20 (20-1, 20-2, ...) include disaster prevention managers and disaster prevention personnel who work at disaster prevention centers and manager's rooms, and fire prevention personnel. This includes security company personnel who patrol the target property, and disaster prevention personnel designated for each floor by the companies that have moved into the building.

(Preliminary fire determination and fire determination)
The fire alarm equipment 10 of this embodiment takes an R-type (Record-type) fire alarm equipment as an example. A unique address is set for each fire detector 16, and the receiver 12 transmits a batch A/D conversion command signal at a predetermined period, for example, a one-second period, and all the fire detectors 16 are detected by, for example, a sensor section. A/D converts the smoke concentration or temperature detection signal to hold the smoke concentration detection value or temperature detection value, and then transmits a call signal that sequentially specifies the sensor address to detect the smoke concentration from each fire sensor 16. Polling is performed to return a response signal including the detected value or temperature detected value.

The fire detector 16 detects, for example, when the smoke concentration detection value reaches a predetermined preliminary fire judgment value, for example, 3%/m, which is lower than a predetermined fire judgment value, for example, 10%/m, for determining a fire by the receiver 12. It is determined that there is a preliminary fire, and a fire interrupt signal is transmitted to the receiver 12. Note that the fire interrupt signal is, for example, an all-1-bit signal that invalidates all signals being transmitted and received through the signal line 14.

The receiver 12, which has received the fire interrupt signal from the fire detector 16, transmits a group search command signal specifying the group address, performs a group search to identify the group address that responded with the fire interrupt signal, and then , sends an intra-group search command signal that sequentially specifies the sensor addresses within the searched group address, and sends the address of the fire sensor 16 that responded with a fire interrupt signal, that is, the address of the fire sensor 16 that was determined to be a preliminary fire. and output a cautionary warning (pre-alarm) indicating a preliminary fire.

Subsequently, when the smoke concentration detection value from the fire detector 16 that has determined that there is a preliminary fire reaches a predetermined fire determination value and satisfies a predetermined fire determination accumulation condition, the receiver 12 transmits the signal continuously for a predetermined number of times, for example. When the smoke concentration detection value exceeds the fire judgment value, it is determined that there is a fire, and a fire alarm is output by the main sound ringing or district sound ringing, as well as interlocking control of predetermined smoke prevention equipment, etc., and transfer notification to external equipment. Performs fire alarm operations including output.

(Identification of fire signs and disaster prevention support)
The fire detector 16 detects, for example, smoke concentration when a predetermined fire sign judgment accumulation condition is satisfied in a state where the smoke concentration detection value exceeds a preliminary fire judgment value of 3%/m which is lower than the fire judgment value of 10%/m. When the detected value exceeds the preliminary fire judgment value a predetermined number of times in succession, it is determined that it is a sign of a fire, and a support activation signal is transmitted from the antenna 18 to the mobile phone terminal 20 (20-1, 20-2, 20-2, etc.) via the wireless LAN network. ...). This support activation signal includes the address of the fire sensor 16 that has been determined to be a sign of a fire.

Further, the fire sign countermeasure information includes an operation instruction for confirming the installation site of the fire detector 16 that has been determined to be a fire sign by a person concerned, and transmitting a response indicating whether there is a fire or non-fire as a result of the confirmation.

The mobile phone terminals 20 (20-1, 20-2, ...) that have received the support activation signal from the fire detector 16 use the position information of the fire point included in the support activation signal and the disaster prevention information stored in advance. Based on the map information of the building, etc. (floor map, etc.) included in the support information, map information showing the fire point and the own device (positions of the mobile phone terminals 20-1 and 20-2) is displayed on the screen. As a result, those involved can grasp the location of the fire point relative to the current location of the mobile phone terminal 20 (20-1, 20-2,...) from the screen display of the map information, and take actions to confirm the scene displayed on the screen at the same time. Based on instructions, you can go to the fire spot location and check the scene.

On-site confirmation of the location of the fire point based on the judgment of fire signs is done by humans, so if there is a fire, it can definitely be confirmed that it is a fire.Furthermore, since the fire is in its early stages, it is necessary to extinguish it in the initial stages using a fire extinguisher, etc. On the other hand, if the cause of the fire is smoke or steam from smoking or cooking, it can be confirmed that it is not a fire.

The person concerned who confirmed the scene detected the fire detector 16 that determined the fire confirmation signal or non-fire confirmation signal as a sign of fire by touch operation on the screen of the mobile phone terminal 20 (20-1, 20-2, . . . ). Send to.

When the fire detector 16 receives a fire confirmation signal, it transmits a fire confirmation signal to the receiver 12 via the signal line 14, and performs a predetermined fire alarm operation, interlock control, transfer control, etc. based on the confirmation of the fire. .

On the other hand, when the fire detector 16 receives a non-fire confirmation signal, the receiver 12 transmits a non-fire confirmation signal via the signal line 14, stops the caution alarm associated with the preliminary fire determination, and confirms that there is no fire. The receiver 12 is restored based on the restoration operation of the person in charge.
