The EMX LRS Control Unit is a remote control module for programming the flat pack and direct burial sensors. The LRS-C1 provides a relay contact output. This is a required component for the LRS system and designed to be paired with either the LRS-DB (Direct Burial) or LRS-FP (Flat Pack) magnetoresistive sensors to complete your vehicle detector installation.
If you have a large opening requirement, you will need to incorporate a LRS-LC Logic Interface which will allow you to utilize two or more sensors.
It is no longer necessary to make 9 cuts to monitor vehicle presence…
The Loop Replacement System (LRS) features advanced 3-axis, magnetoresistive sensing technology that responds to changes in the Earth’s magnetic field caused by ferrous objects. Three sensing elements provide measurements in the X, Y and Z axes to improve detection sensitivity when used in either above or below ground installations.
The LRS is equipped with our new DETECT-ON-STOP™ or (DOS®) feature, which allows detection only when a vehicle has come to a complete stop. This EMX exclusive feature is a major advantage if you want to ignore cross traffic in tight spaces.
The detector’s compact, loop-less design reduces installation costs when compared to traditional inductive loop technology.
