Arrangement for monitoring and early fire detection for several fire and / or explosion-hazard vessels and / or housings

摘要

The invention has for its object to develop an arrangement for monitoring and early fire detection for fire and / or explosion-prone vessels and / or housing, which at reasonable system costs as an alternative to the currently in the prior art, for example in the switching u. Server cabinets from data centers (e.g. banks, etc.), smoke detectors can be used, and at the same time much cheaper and more precise, as well as much false alarm-proof selective monitoring of a much higher number of "measuring points" (e.g. Server cabinets) using only one evaluation unit, with significantly reduced manufacturing, assembly, maintenance and repair work, high flexibility and high availability, guaranteed even during maintenance work but also during the expansion work of the overall system. The arrangement according to the invention for monitoring and early detection of fire for several fire and / or explosion-prone vessels (1) and / or housings using laser and / or multi-criteria smoke detectors (2) is distinguished, inter alia, by the fact that the devices used in the arrangement Smoke detectors (2) are arranged in pairs either in a duo detector module (3) or in two mutually assigned mono detector modules (4), and are always connected in a two-detector dependency, and that they are connected to each of the monitoring vessels (1) for the fire detection significant points arranged duo detector modules (3) and / or mono detector modules (4) are connected as BUS subscribers via a ring bus (18) to an evaluation unit (19) taking over the power supply of the bus system. The invention relates to an arrangement for monitoring and early fire detection for several fire and / or explosion-prone vessels and / or housings, such as switch and distribution cabinets and electrical engineering devices, IT cabinets and devices, etc.
