Beams or Door Status Switches
Often I will be called to look at warehouses that are quite large and the owner does not have a budget to install overhead door status switches on all the overhead doors or install conduit for each overhead door.
One option that can save money is to install beam detectors across the warehouse which can be done at a lower cost and can reach across hundreds of feet. Bosch motions are excellent quality and as an example if you have a 300 foot side to a warehouse with 15 overhead doors you can install one set of double beams on one side and one on the others and it will cover all the overheads and man doors in that area.
We can go over the pros and cons of beams in a consultation although often they are a great fit.
