VD909 – ‘Dynamite’

solar situe 1
Picture2

Designed for gate installations (including solar and battery operated). Pulse technology for use in free exit/free entry applications. Requires no loops to be cut, sensor does the work of the loops

One length of cable used from sensor direct to the control panel. Self-setting: pre-set to normal sensitivity and tunes itself to best frequency. Proven reliability

With no loops to fit, the installation takes a quarter of the time

Self-setting means no triggering and having to return to site

Hardly any mess as no loops to cut

Self-setting is easy, just simply wire in the 6 wires and job is done

The Dynamite has been a welcome advance in the Loop Detector industry, for free exit applications.

No more unpleasant hours spent digging in loops.  The direct burial cable goes directly from the sensor to the control box, the sensor does the job of the loops.  In addition the module is self-setting which completes an easy installation in a quarter of the time. The VD909 has a very low current draw which makes it ideal for solar applications.

  • Results in the opportunity for greatly increased service life due to the reduced exposure to hazards such as road traffic, pavement movement, pavement deterioration, and roadwork.
  • The fact that the “Mini-Loop” is not installed in the pavement and that the lead-in is very durable allows the “Mini-Loop” to be used in situations such as cobblestone pavements, poor pavements, dirt/gravel roads, and bridge decks.
  • Minimal intrusion into good pavements!

The Diablo “Mini-Loop” is intended to be buried beneath the roadway surface and connected, via lead-in cable, to the Diablo VD909 Detector.

Installation is straightforward.  A 1-in. diameter hole (18-in to 24-in. deep) is drilled for the “Mini Loop”.  A shallow, 1/4-in. saw cut from the hole to the edge of the road provides a path for the lead-in wire.  The “Mini-Loop” with lead-in is inserted into the hole and the hole is filled with dry sand.  Detector loop sealant material is then used to fill the slot and top portion of the hole.

It is important that the “Mini-Loop” be installed in a vertical position and that the vertical position of the “Mini-Loop” be maintained.  Under some soil conditions, installation can be further simplified by installing the Mini-Loop inside a length of PVC pipe (not steel pipe) with an interior diameter of about 1 inch.  In this case, the hole must be slightly larger than the outside diameter of the PVC pipe, typically 1-5/8-in. or less.  After insertion of the PVC pipe and Mini-Loop, all cavities are back-filled with fine, dry sand and the installation completed in the normal manner.

See Mini Loop Installation for complete instructions and specifications.
