HOUSE INFORMATION BOARD AND SECURITY SYSTEM FOR MULTIPLE DWELLING HOUSE, AND SUBORDINATE EQUIPMENTS FOR HOUSE INFORMATION BOARD

摘要

PURPOSE: To select which of a 1st and a 2nd alarm is generated on an alarm monitor board in case of alarm generation by outputting no fire signal to the alarm monitor board when the 2nd fire alarm based upon a signal from a residence receiver is generated. ;CONSTITUTION: When a fire sensor detects a fire and outputs a detection signal to a sensor line, an interphone 1 detects the detection signal through a test terminal and generates the 1st fire alarm. When a resident presses an emergency button in response to the 1st fire alarm, a fire confirmation signal is outputted from the interphone 1 to the residence receiver and then a fire control signal is inputted from the residence receiver, so that the interphone 1 generates the 2nd fire alarm. At this time, a transmitted signal transmitting and receiving circuit 13 for the multiple divelling house outputs not fire signal to the alarm monitor board. Therefore, the alarm monitor board never generates a fire alarm in case of the 2nd fire alarm.;COPYRIGHT: (C)1996,JPO
