PROBLEM TO BE SOLVED: To register attendance or absence momentarily and to attain required display by allowing each house to a radio individual remote control transmitter so as to send a required signal to an attendance display panel incorporating a remote control receiver. SOLUTION: A plurality of radio individual remote control transmitters are used to send an attendance or absence signal without contact to a multi- station attendance display panel and the attendance display panel incorporating a remote control receiver receives the signal to register the attendance momentarily and to display the attendance on an individual display section. An external output signal of the attendance display panel is used to be interlocked with a burglar-proof device or an energy saving installation. Furthermore, an individual remote control transmitter is used for each house and each burglar-proof signal is given to each individual channel and a notice is given to each individual channel making an alarm by means of a buzzer and an LCD message. |
