Alternatively, in a fire detector that sends back data indicating the detection level of smoke, heat, etc. of a fire phenomenon in response to a polling call from a receiver, an optical transmitting/receiving means for transmitting and receiving signals with a wireless terminal; information requesting means for requesting necessary information from the receiver via a transmission device in response to an information data request from the wireless terminal received by the optical transmitting/receiving means; information data transmitting means for transmitting the information data of the receiver to the wireless terminal via the optical transmitting/receiving means; The present invention is characterized in that it includes change data sending means for sending change data to the receiver via the receiver.

[Example] An example of the fire detector of the present invention will be described in detail based on the drawings.

FIG. 1 is a system configuration diagram showing one embodiment of the entire fire alarm device using the fire detector of the present invention.

This fire alarm system includes a receiver 1 that performs centralized monitoring and displays a fire alarm in the event of an emergency, a transmission line 2 extending from the receiver 1, and a plurality of fire detectors 3 connected to the transmission line 2. It consists of a fire detector 3 and a wireless terminal 4 capable of transmitting and receiving signals using optical transmitting and receiving means.

FIG. 2 shows an external view of the fire detector 3 shown in FIG. 1, which includes a light-receiving element 35 and a light-emitting element 36 forming an optical transmitting/receiving means.

FIG. 3 shows an external view of the wireless terminal 4 of FIG. 1. It includes a light emitting element 41 and a light receiving element 42 forming a light transmitting/receiving means with the fire detector 4, a push button switch 44 for inputting commands or data, and a display 43 for displaying addresses, attribute data, etc.

Normally, the receiver 1 cyclically calls each fire detector 3 via the transmission line 2 to request detection data. The called fire detector 3 returns data indicating the detection level of heat, smoke, etc. of the fire phenomenon. In this way, the receiver 1 centrally monitors fires based on the detection data from the plurality of fire detectors 3.

During maintenance inspections, etc., the inspector on the fire detector 3 side (monitoring area) checks the address of the fire detector 3, the attribute data stored in the receiver 1, the monitoring mode (normal monitoring, fire test, etc.), etc. If you do not know or want to make these changes, you can do so by pointing the wireless terminal 4 at the fire detector 3 to be accessed and operating the push button switch 44 corresponding to the command.

At this time, necessary data such as the address and attribute data are displayed on the display 43 of the wireless terminal 4.

Then, when the receiver 1 calls, necessary data is extracted and sent back via the transmission device 30. Note that the detection data of the detection unit 33 may be taken in when the receiver 1 calls. When the optical transceiver 34 receives a command following a specific code from the wireless terminal 4, it outputs this command signal to the central processing unit 32. .

When the central processing unit 132 receives this command, it first identifies the command.

If the type of command is an address data request, the address data stored in the storage device 31 is retrieved and the optical transceiver 34 outputs this address data to the wireless terminal 4. The unique address of the fire detector 3 is displayed on the display 43 of the wireless terminal 4.

If the type of command is an address change command, the central processing unit 30 takes in the address data following this command code and rewrites the address data stored in the storage device 231.

If the type of command is an information data request, the central processing unit 32 temporarily stores the request command in the storage device 31. When the receiver 1 makes a polling call, the request command is sent as a return signal via the transmission device 30. When the receiver 1 receives a data request command from the fire detector 3,
The information data corresponding to this command is sent to this fire detector 3.
