Breaking News
In with the new, out with the old...
From 1st July 2009 it will be time to say good bye to two of GJD's faithful lighting controllers. The 2-Zone and 4-Zone Solitaire key pads have been industry favourites for almost twenty years. As part of GJD's ongoing product development strategy we decided it was time for a product face lift and the opportunity to offer more functionality. This heralded the arrival of the feature rich DygiZone lighting controller/enunciator and the even more powerful 4-Zone Expansion unit.
We hope that our customers will embrace the new products and please rest assured that we will always retain strategic spares for the Solitaire range.

When using beams to secure a site perimeter it is all too easy for beams to be blocked leaving gaps in the perimeter protection. GJD's new D.A.A.M. reports any open zones prior to the alarm system being set.
