We have designed the new LP D-TEK vehicle loop detector with the following objectives in mind:
1. Low current consumption, maximum 9 mA current draw in fail safe or fail secure.
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.
7. Compact package to allow easy installation into small operator housings.
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.
