Abstract
PURPOSE:To confirm whether a lamp informs that a sensor to be checked is actually operated or not by utilizing the signal of a lamp for displaying a warning area generated at every warning area connected to the sensor. CONSTITUTION:When a sensor 1 is operated for checking, the warning area lamp of a receiver 2 of fire alarm facilities is lighted up, and the lighting signal is removed to a signal line 3. The signal is converted to a binarization signal by an encoder 18, a serial signal from an asynchronous parallel-serial convertor 19 is converted to a sinsoidal frequency by a phase convertor 20, a signal generated by a high frequency generator 6 is modulated, and the signals are transmitted to a checker. The signals received by a bar antenna 11 and an HF amplifier 12 at a checker side are demodulated 13 and 14, and they are sent to a light emitting diode display 17 as the signals. A receiving condition and a warning area number lighted up by the receiver 2 is displayed by the display 17.
