The Flexible, Completely Modular CCTV Telemetry/Matrix System
UBS2000
One of the main advantages of the Telematrix system is the relative ease in which both large and small matrix systems may be conceived and assembled from a selection of only five basic components. The five main components forming the Telematrix are the Enclosure, the CPU Card, the Input Card, the Output Card and the Input Device (keyboards etc.). Cards simply slide into the enclosure on nylon card guides and secured by two small screws. Keyboards are connected by a flexible 4 core telephone lead and plug into the Telematrix using standard BT plugs (X2110, X2120) or via a standard 4 pair CAT5 cable terminating on RJ45 IDC connectors (X2140).

Utility Locator
VM-850
Using the correct frequency makes a world of difference when locating buried utilities. The depth of the utility, size, material, and amount of congestion (proximity of other utilities) all need to be taken into consideration for the correct frequency selection. Large diameter, direct buried pipes with bell housing ends that use insulators and rubber gaskets, such as water or gas require a higher frequency while smaller diameter, well-grounded direct buried or long distance in conduits work, better with a lower frequency. The VM-850 operates at a much lower frequency of 9.82kHz which is ideal for smaller diameter utilities such as CATV, power and telephone with less bleeding onto adjacent services.

Telephone & Exchange Tester
ETT 10
Maintenance statistics of telephone networkshave shown that for most of the failures, theexchange - line - subscriber (EXCH-LINE-TEL) sections are responsible. Accordingly, the first step of the troubleshooting procedure is to locate the breakdown spot, i.e. to find out whether thefailure source is within the exchange, the subscriber site or in the line (local loop). Thisproblem can be easily solved by theTelephone & Exchange Tester ETT 10, in most cases without requiring the technician to visit the subscriber or the junction boxes along the line.
