摘要： PROBLEM TO BE SOLVED: To provide a fire alarm system capable of inspecting efficiently a fire sensor or the like installed in each dwelling unit of an apartment house. SOLUTION: A testing part is formed in an alarm device arranged in each dwelling unit of the apartment house, and the testing part executes automatically a test on the fire sensor or the like. Then, the result of the executed test is transmitted from the apartment house to a remote monitoring center through a communication network. By giving a test function to the alarm device like this, the test can be executed automatically inside the dwelling unit without executing the test by an inspector by connecting an external tester from the outside of the dwelling unit. In addition, since the test result is transmitted from the apartment house to the remote monitoring center by utilizing a prescribed communication means, the test result can be acquired in the monitoring center. Hereby, the test can be executed automatically without dispatching the inspector to the apartment house, and efficient inspection can be realized.

摘要： PURPOSE:To make it possible to limit a communication area while eliminating the need for an electromagnetic shield, by providing a communication cutting-off area in the communication area and then by lowering the sensitivity of a receiver in this area. CONSTITUTION:Communication areas 1a and 1b and communication cutting-off area 2 are covered with loop antennas 11a and 11b, and 21; and antennas 11 and 11b are fed with communication waves from transmitting methods 10a and 10b. Area 2, on the other hand, is fed with an unmodulated carrier wave from transmitter 20. Then, receiver 5, once entering area 1a, receives a communication signal from method 10a. Its current reception level is E10 and a wave received from transmitter 20 is held at level E20 through the operation of AGC. Once receiver 5 enters area 2, radio wave E10 has sensitivity lowered by DELTAE with the unmodulated carrier wave, limiting area 1a.

摘要： PROBLEM TO BE SOLVED: To provide the image recorder that can record image data for a long time and detailed image data for a short time regardless of a small storage capacity and to provide the fire monitoring system using the image recorder. SOLUTION: Image data photographed by a digital camera 1 are sequentially overwritten on data in a storage area of an image storage section 11 by a short period under the control of a write control section 13. The control section 13 receiving a trigger signal TRG controls the image storage section 11 to write image data of a prescribed number and to store the image data. On the other hand, image data from the digital camera 1 are sequentially overwritten in data of a storage area of an image storage section 11 by a long period under the control of a write control section 14 till the control section 14 receives the trigger signal TRG. When a read control signal PLY is given to a display control section 18, the image data having been stored in the image storage sections 11,12 are read according to the recording time under the control of the display control section 18 and the data are displayed on a display device 6 via an output section 19.
