What is the difference between Free Exit Probe and DSP-14S?
Overview
Although both devices detect vehicles using magnetometer-based technology, they are not interchangeable. Each sensor is designed to work with specific Diablo Controls detectors.
| Feature | Free Exit Probe | DSP‑14S |
|---|---|---|
| Sensor Type | 1‑axis magnetometer | 3‑axis magnetometer |
| Primary Use | Free exit only | Safety loops and free exit |
| Detection Type | Pulse only | Pulse or presence |
| Typical Detector Pairings | DSP‑55, DSP‑10, XLP-8 and any Diablo detector with Pulse or Probe Mode | DSP‑14M |
| Visual Identifier | Black wire, “Free Exit Probe” tag | Yellow wire, “DSP‑14S Sensor” tag |
Free Exit Probe
The Free Exit Probe is a 1‑axis magnetometer vehicle sensor specifically designed for free exit applications only. It detects a vehicle as it moves through the detection zone and generates a short pulse output to trigger a gate to open. It cannot be used for safety or obstruction detection and must never be used as a safety loop. The Free Exit Probe will have a black wire with a "Free Exit Probe" tag on top of the magnetometer.
DSP-14S (3-Axis Magnetometer)
The DSP‑14S is the sensor component of the DSP‑14 Detection System, which consists of:
- DSP‑14M (master detector)
- DSP‑14S (3‑axis magnetometer sensor)
Unlike the Free Exit Probe, the DSP‑14S supports both free exit and safety / presence detection applications.
DSP-14S will have a yellow wire with a "DSP-14S Sensor" tag on top of the magnetometer.
Which Should You Use?
- Choose the Free Exit Probe if:
- You only need free exit pulse operation
- You want a simple, cost‑effective solution
- Safety detection is not required
- Choose the DSP‑14S if:
- You need safety loop or presence detection
- You want a simple, cost‑effective solution
- You want orientation‑independent installation
