Japanese Patent JPH0518159
Kind Code:
B2
Abstract:
In the monitoring system which is intended for buildings, rooms and objects a multitude of measuring or detecting and signaling stations are series connected to a central signal station. Each of the detecting and signalling stations transmits information about its instantaneous state, which may be any one of standby, warning, alarm, malfunction, to the central signal station by means of an electronic circuit member. The electronic circuit member affords the following advantages: identification of the number and of the location of the detecting and signalling station in the case of changes in the state of the detecting and signalling station; detection and localization of malfunctions such as a short-circuit or an interruption in the signal line; cut-off of the short-circuited signal line section from the remaining signal line; saving of installation expense; greater flexibility in the evaluation of the states of the detecting and signalling stations and in the initiation of appropriate measures or counter-actions; operation of control devices via the signal line; monitoring of the electronic circuit member.
