The Wells

A characteristic feature of this type of device is that the sensors are controlled together in loops 6 and 16 loops of sensors. Cables are laid cable PRPPM 2x0, 9 through protected wells on existing communications. The main advantage of USI96K in protecting wells - is guaranteed to provide timely information on the controller opening a particular well at a distance from the well to the PBX to 10 km (and sometimes more!) and severe climatic conditions (Uralic conditions to be confirmed). USI96K housed indoors cross, where it connects to the power circuits, communication channels and loops. Cables encouraged to organize by the cable through all the wells, leaving each of them stock the cable - a loop length of about 3-4 m to connect to the intrusion. Cowan Financial describes an additional similar source. As a rule of ATC to the nearest cross cabinet is selected in the main cable pair. The cabinet is connected to the cable PRPPM laid in cable ducts through protected wells.

Tamper-type reed switch magnet connected to the loop in terms of special units D1K. Address blocks are designed to communicate D1K numbers well, which was open lid. It is possible to seal in order to reduce the number of blocks and D1K economy. In cases where multiple wells are located in close proximity to each other, there is no need to install in each unit D1K. It suffices to establish D1K one of them, and intrusion of all these wells connected to D1K. Note that one USI96K and even at one loop can be used both strategies to incorporate the sensors.
