Abstract

PURPOSE:To obtain a compact and inexpensive fire signal receiver facilitating the rewriting operation of ROM by providing a connector, a reading means, a rewriting means, etc., for an IC card. CONSTITUTION:When the change of layout within a building, the addition of the option of a fire alarm equipment, etc., are asked by a user, setting data which should be updated is stored in the IC card 25. The IC card 25 memorizing changed design data is inserted to the insertion part 33 of the IC card 25 provided at the unit board 21 of a display operation unit 20 and connected to the connector of a control substrate 24. If power source is started then, CPU (the reading means and the rewriting means) reads changed set data in the IC card 25 and rewrites old set data stored in rewritable ROM to new set data. This realizes the compact and inexpensive fire signal receiver which facilitates the rewriting of ROM at the time of the addition of the option and extending the fire sensor, etc.

INDUSTRIAL APPLICABILITY The present invention is connected to an IC card provided on a control board and storing update setting data.
A C card connector, a reading means for reading the setting data stored in the IC card, and a rewriting for rewriting the setting data stored in the rewritable memory mounted on the control board to the setting data read by the reading means. Means and IC
A fire receiver was constructed with an insertion section for inserting the card into the connector on the control board.

Further, an IC card connector, which is provided on the control board and is connected to an IC card in which update setting data is stored, a reading means for reading the setting data stored in the IC card, and the control board. Rewriting means for rewriting the setting data stored in the rewritable memory mounted in the setting data read by the reading means, a display operation unit having a unit board to which a control board is attached, and provided on the unit board, A fire receiver provided with an insertion portion for inserting the IC card into the connector on the control board was constructed. Further, a fire receiver having a holding member that surrounds the IC card from both sides in the insertion portion is configured. Furthermore, a fire receiver was constructed with an inclined surface that widens the entrance side at the insertion part.

As a result, when an option is added after the product is shipped or a fire detector is added like a conventional fire receiver, a connector of a ROM rewriting device separately provided is connected to make a new setting. There is no need to rewrite the data. Therefore, when rewriting the ROM, it is necessary to carry a small IC card each time.
The OM can be rewritten.

Therefore, the rewriting operation of the ROM is extremely easy, and the setting data can be updated even for the maintenance personnel who do not have a special technique, so that the problems in the past can be alleviated. In addition, since the IC card insertion portion is provided on the unit board as in the first embodiment, the structure is further strengthened as compared with the conventional structure in which the IC card insertion portion is inserted into the notch portion of the printed circuit board, and there is little fear of damage due to external force. In addition, since the insertion portion can be integrally molded with the resin unit board, it can be made compact without increasing the number of parts. In particular, if the insertion portion is formed with a sloped surface that widens on the inlet side, there is also an advantage that the IC card can be connected to the connector smoothly and reliably.

Therefore, according to the present invention, it is possible to provide a fire receiver which is compact and inexpensive, as well as being able to rewrite the ROM very easily.
