EMX CarSense 101 CS101-LV Vehicle Motion Detector Replacement Module
The CS101-LV is the control module portion of the EMX CarSense 101 system. The installed sensing probe monitors the magnetic disturbance created by a moving vehicle, and the module provides a relay output to the gate operator or access-control device.
This detector is commonly used as a free-exit sensor on driveway gates because it can detect a vehicle approaching the gate from inside the property without requiring a remote, keypad, or intercom command. It may also be used to trigger cameras, lights, alarms, or notification systems when wired to compatible equipment.
Because this row is for the module only, the existing probe, burial location, cable condition, socket, and power supply should be checked before replacing it. A bad probe cable or incorrect socket wiring can mimic a failed module.
Compatible With
- EMX CarSense 101 vehicle motion detector systems
- CS101 direct-burial sensing probe installations when the probe and wiring are compatible
- Gate operator free-exit inputs that accept the module relay output
- Security, camera, alarm, and access-control devices using compatible dry contact input
- Low-voltage applications using compatible CS101 power requirements
- Driveway and lane applications where moving-vehicle detection is required
- Standard 11-pin socket installations where wired for the CS101 module

Technician Note
If the gate does not open from the free-exit sensor, test the probe and cable before replacing the module. A damaged direct-burial probe lead or water-filled splice can cause the same symptom as a bad detector.
Before Ordering
- Confirm you need the module only, not a complete CarSense kit with probe
- Verify the existing probe is a compatible CS101-style probe
- Check the 11-pin socket wiring and supply voltage
- Confirm the application needs moving-vehicle detection rather than stationary presence detection
- Inspect probe cable damage or splices before replacing the module
Important Ordering Warnings
- The CS101 detects moving vehicles and should not be used as the only device to hold a gate open for a stopped vehicle
- Do not use a free-exit detector to bypass required photoeyes or safety edges
Professional Advisory
For installation or replacement on a powered gate, door, or access-control system, follow the equipment manufacturer instructions and local safety requirements. If wiring, monitoring, or unsafe movement is uncertain, use a qualified gate or door technician.
Product Questions
Is CS101-LV the complete CarSense system?
No. This row is for the replacement control module only. A complete system also requires a compatible sensing probe and proper wiring.
What does the CarSense 101 detect?
It detects moving vehicles by sensing magnetic changes from ferrous vehicle mass near the probe.
Can it detect a stationary vehicle?
No. The CS101 is a vehicle motion detector and is not intended for stationary presence detection.
What is a common use for CS101-LV?
It is commonly used as a free-exit detector for automatic driveway gates.
What related part numbers should be checked?
Common related references include CS101, CS-101, CS101-LV, CS-101-LV, XC101-LV, and EMX-2101-1.
