摘要： The analog smoke detector (3a) includes a transmission/reception circuit (31) for receiving an A/D conversion command from a control panel through a transmission path (8). It is composed of a light emitting element (38a), a test light emitting element (38b), a light receiving element (39), a light emitting element drive circuit (36), an amplifying circuit of received light (40) and transistors (Q1, Q2, Q3). It is further provided with a MPU (32) which includes a CPU, a ROM storing determination levels, a working RAM and the like An EEPROM (33) is externally connected to the MPU (32).
It includes a light emitting element control circuit (36) for outputting a drive pulse based on the light emission control pulses P1, P2 output from the MPU (32) and the detecting light emitting element (38a) for emitting light for receiving dispersed light caused by smoke generated by a fire.

摘要： The body of a detector is connected to a connection portion, a ten-key pad and a + 1 key are used to set the address, and a writing key is depressed to write the address on a memory. When a mode switch is set to an analog mode and then a test key is depressed, a test of the detector can be performed in such a manner that address information of the body of the detector is read and indicated through the connection portion. Furthermore, when a test cable is connected to a terminator of a circuit in the detector followed by switching the mode switch to a terminator side and depressing the test key, a test of the terminator can be performed. According to the present invention having the foregoing structure, a multiplicity of addresses can be set in a short time, satisfactory portability can be realized and a test of the detector and that of the terminator can be performed.
