RADIO AUTOMATIC INSPECTOR FOR AUTOMATIC FIRE ALARM EQUIPMENT OF DIGITAL MACHINE PROVIDED WITH TRANSCEIVER, TESTER FOR SENSOR PROVIDED WITH LOOP ANTENNA, LOOP ANTENNA FOR THE TESTER, AND HOLDER FOR THE INSPECTOR

摘要

PURPOSE: To facilitate the inspection work or a worker who carries a radio automatic inspector with him especially by adopting a small-sized and light- weight transceiver in a radio machine part. ;CONSTITUTION: The radio automatic inspector whose transmission part of a transceiver T having a high frequency, for example, in 100 to 460MHz band is connected to a digital signal generator 4 and the radio automatic inspector whose reception part or a transceiver R is connected to a digital signal converter 10 are provided. A tester 12 for a sensor 3 is provided with a loop antenna 13. In this case, the voltage of the terminal number changed by operation of the sensor 3 is converted to a signal by the digital signal generator 4 and is transmitted to the transceiver T. This signal is received by the transceiver R, and operation confirmation is displayed as a number on a display device 17 of the digital signal converter 10. The reception sensitivity is raised by the loop antenna 13 provided in the tester 12 for the sensor 3. Thus, the inspection work is facilitated.;COPYRIGHT: (C)1996,JPO
