IRWL Installation Tips

LightGuard’s in-roadway warning light systems operate on low voltage Direct Current (DC) power and can use either solar power or Alternating Current (AC) power which is converted to 12v DC.

To ensure system reliability, LightGuard’s IRWL crosswalk system is hard wired. The installation of a complete IRWL crosswalk system for a typical 2-lane mid-block crosswalk can be completed within 1-3 days. The installaMaking the saw cut across the road.tion can be undertaken by City Public Works crews or an independent installing contractor.

Installation time varies based on the number of traffic lanes, IRWL equipment chosen and installing crew skill. Most IRWL systems are retrofitted to existing crosswalks.

The first step is determining the layout pattern, or placement of each IRWL module according to the lane lines, parking lane, sidewalk and crosswalk locations. (See Visual Installation Guidelines above, IRWL layouts and Zone of Convergence).

Once the layout is determined, the next step is to saw cut for the IRWL system wiring. The saw cut is generally no wider than .5″ wide and no greater than 2″ deep. Either conduit or direct burial wire can be utilized. Once the saw cut has been completed, the locations for the base plates are identified and the depression holes are bored into the road surface. (For complete in-depth instructions please see the LightGuard Installation Manual.)

The standard 10″ diameter x 1.5″ deep base plate is made of a ultra-high strength composite material. It is designed to be permanently embedded into the roadway. This allows for any in-roadway warning light (IRWL) signal head that becomes damaged or inoperable to be repaired with an easy to install replacement.

For “snow country” use, we offer a Snow Plow Blade Resistant Base Plate. The case hardened steel base plate has wing tips on either side of the IRWL signal head and a center nose bridge. When a snow plow blade strikes the base plate, the blade is lifted up and over the top of the IRWL signal head. The steel base plate is 14″ in diameter and is no more than 1.5″ deep.
