Cartell CW-SYS Wireless Dual Purpose Exit Wand Vehicle Detection Sensor
The Cartell CW-SYS is the wireless version of Cartell's vehicle detection approach for gate and driveway applications. Instead of placing a wired sensor and running lead cable all the way back to the operator, the CW-SYS uses a self-contained sensing puck with wireless transmission to communicate with the matching receiving equipment. This is useful when the exit point is far from the control box, when a driveway is already finished, or when trenching across hardscape would be expensive. It can be used as a free-exit device for automatic gates or as a vehicle-detection trigger for supported driveway notification, security, and automation setups. Because wireless performance depends on distance, terrain, enclosure placement, battery condition, antenna position, and interference, the receiver location and site layout should be reviewed before installation. The CW-SYS should be selected when a wireless sensor is the right fit; for hardwired jobs with an available cable path, the CP-4 may be the better choice.
Compatible With
- Automatic gate operators with a compatible free-exit, open, or accessory input when paired through the CW-SYS receiver/output.
- Residential driveway gates, estate gates, farm gates, gated entries, parking entrances, and light commercial gate applications where wired sensor cable is difficult to install.
- Supported Cartell wireless driveway notification and sounder applications where the system is configured for vehicle arrival or exit notification.
- Security, camera, alarm, and home automation systems that accept a compatible relay/contact trigger from the receiving device.
- May be used with many gate opener brands, including select Nice Apollo, Linear, GTO, Mighty Mule, LiftMaster, DoorKing, Viking, FAAC, HySecurity, Ramset, and similar systems, when the receiver output is wired to the proper operator input.
- Use wired CP-4 instead of CW-SYS when the installation requires a hardwired sensor path, no battery maintenance, or when site conditions make wireless transmission unreliable.

Technician Note
Wireless vehicle detectors solve a different problem than wired probes. Before installing, test the receiver location and confirm the gate operator responds correctly to the output contact. Do not bury the sensor puck permanently until the detection location and wireless performance have been tested with the type of vehicle expected on the property.
Before Ordering Checklist
- Confirm the job needs wireless CW-SYS instead of wired CP-4.
- Confirm the gate operator or automation device has a compatible input for the receiver output.
- Check the expected wireless distance and line-of-sight conditions.
- Plan future battery access for the sensor puck.
- Confirm whether the project needs gate free-exit only, driveway notification only, or both functions.
Professional Advisory
For gate operators with unfamiliar accessory terminals, unreliable gate movement, or missing safety devices, have the system checked by a qualified gate technician before adding vehicle detection accessories.
Important Ordering Warnings
- Do not order CW-SYS as a direct plug-in replacement for a wired CP-4 unless the installation is being converted to wireless.
- Do not use CW-SYS as a safety loop, photo eye, or entrapment protection device.
- Wireless performance must be tested at the site before final burial or permanent mounting.
Product Questions & Answers
Is the Cartell CW-SYS the same as the CP-4 wired sensor?
No. Both are Cartell vehicle-detection products, but the CP-4 is wired back to the operator while the CW-SYS uses wireless communication between the sensor puck and receiving equipment.
Can CW-SYS open an automatic gate for exiting vehicles?
Yes, it may be used as a wireless free-exit system when the receiver output is connected to a compatible free-exit, open, or accessory input on the gate operator.
What affects wireless range on the CW-SYS?
Distance, line of sight, receiver location, terrain, metal structures, battery condition, antenna position, and radio interference can all affect performance. The advertised range should not be treated as guaranteed for every site.
Does this replace gate safety photo eyes?
No. CW-SYS is a vehicle activation and notification product. It does not replace monitored photo eyes, safety edges, obstruction sensors, or other required gate safety devices.
When should I choose CW-SYS instead of a wired exit wand?
Choose CW-SYS when trenching or running a long sensor cable is difficult, such as finished driveways, long entrances, or retrofit properties. Use a wired CP-4 when a hardwired sensor is preferred and a proper cable path is available.
