D-TEK Vehicle Loop Detector - Operating Instructions

We at EMX have designed the new D-TEK vehicle loop detector with the following objectives in mind:

1. Compact package to allow easy installation into small operator housings.
2. All the controls are accessible from the outside for easy installation and operation.
3. Integral loop conditioner is provided, to enable detector operation with marginal loops.
4. Provide all the features and controls necessary for a variety of applications.
5. Use metal housing for maximum durability and RF blocking.
6. Provide maximum surge protection on all inputs and outputs of the detector.

We took extra care to achieve and exceed these objectives. For example the controls are divided into two
groups. The group on the front of the detector is for basic operation and the group on the back of the detector
is for advanced settings. This way the more advanced settings are not visible to the casual user.

There is no skimping on the quality in the D-TEK detector. The housing is made from aircraft quality
anodized aluminum. All the switches have gold plated contacts and are sealed for protection. The detector is
protected by easily replaceable fuse, snubbing circuitry on the relay contacts, metal oxide varistor on the
power input and triple protection on the loop input.

The D-TEK features are extensive and they include full loop diagnostics with frequency counter, 10
sensitivity settings, delay and extend features, "fail safe" and "fail secure" operation, automatic sensitivity
boost, pulse or two presence relay operation and more.
