Installation
Read the following list of tips prior to beginning the installation process.
This will save significant time in the long run.
 Every time the settings are changed on the LRS-C1 or the sensor is moved, press the
RESET button on the LRS-C1.
 The LRS-FP and DB sensors are sensitive to minute changes in the magnetic field around them.
Power lines, transformers, and other electrical devices located in the vicinity of the sensor that
produce transients could cause disturbances in the magnetic field that may result in triggering the
detector. Avoid installation of the sensor near these devices.
 Do not mount on any moving surface, such as bridges or walkways that may vibrate under traffic.
The sensor must always be installed in such a way that it remains completely motionless.
Any movement will cause the sensor to trigger.
Sensor Installation
1. Determine the location for the LRS-FP or DB sensor installation. The sensor must be at least
6 feet away from all moving metal. If rebar is present in the roadway, the sensor must be
installed above it.
2. Tape the sensor and lead to the pavement and connect the sensor to the LRS-C1
(see Wiring Connections).
3. Connect the LRS-C1 to the operator according to the operator’s instructions.
4. Configure the DIP switch and sensitivity settings according to preferences (see Settings & Display
for more information). Press the RESET button on the LRS-C1 after changing settings.
5. Test the product. Without moving the sensor or the lead going to the sensor, drive a vehicle near
the sensor. When the vehicle is five feet from the sensor, “9” will be displayed on the ULTRAMETER
TM
display. Once the vehicle is the desired distance from the sensor, take note of the number displayed
on the ULTRAMETER
TM
and change the sensitivity setting (10-position rotary switch) to match that
number. Move the test vehicle away from the sensor to remove it from the detection zone
(the ULTRAMETER
TM
display should be blank). Press the RESET button on the
LRS-C1 and do not move the sensor or lead. Retest the sensor by moving the vehicle into and out
of the detection zone to make sure the set-up and location are working as intended.
