In an installation monitoring system, conditions at various sites of the installation are routinely monitored with a plurality of sensors (1-5). The actual signals of the sensors (1-5) are routinely stored via multiple channels in a first memory 24, and in the event of an alarm condition the actual signals lying chronologically around the alarm condition are transferred into a second memory 25 and then are subjected to a detailed automatic and/or manual examination by a supervisor. The sensors may be acoustic, optical or heat sensors. The installation may be a gas distribution plant which is monitored for leakage. |
