BEA MATRIX-D-12-24 Loop Detector - 10MATRIXD1224 - 12-24V AC/DC Vehicle Sensor
The BEA MATRIX-D-12-24 is the low-voltage dual-loop member of the Matrix detector family. It allows two independent inductive loops to be connected to one detector, with separate outputs for each loop. In a gate or parking installation, that can be useful when one loop is used for free exit and another for reverse, or when an industrial door or barrier lane needs two detection zones controlled from the same detector location.
Correct selection depends on more than the BEA brand name. The Matrix-D is a dual-channel detector, so the control panel must support the required loop functions and the wiring must match the detector base. The 12-24 VAC/VDC version should be used only where the control box provides the correct low-voltage supply. If the original system used a 110V detector, a single-loop detector, or a different output style, the installation should be reviewed before ordering.

Technician Note
Dual-loop detectors are often misordered when the original system only used one loop. Confirm how many loop inputs are actually wired and whether the control panel needs separate outputs before replacing a Matrix detector.
Before Ordering
- Confirm two loops are present and both are being used
- Confirm 12-24 VAC/VDC power is available at the detector location
- Match the original detector base, terminal wiring, and relay output requirements
- Test each loop for continuity, insulation problems, and proper inductance
- Document which loop is free exit, reverse, presence, or pulse before rewiring
Important Ordering Warnings
- Do not use this low-voltage model in place of a 110V detector without rewiring for the correct power
- Do not assume a dual-channel detector will fit a single-channel detector socket
- Do not bypass monitored safety devices when adding or replacing loop detection
Professional Advisory
Because loop detector outputs can affect gate movement, reverse behavior, and hold-open timing, a qualified technician should verify the wiring and safety functions after replacement.
Product Questions and Answers
How many loops can this detector monitor?
This Matrix-D version monitors two independent loops and provides separate relay outputs for supported dual-loop applications.
Can it replace two single-loop detectors?
It may replace two single-loop detectors only when the controller layout, voltage, socket/base wiring, and output requirements support a dual-channel detector.
What is the benefit of dual-loop detection?
Dual-loop detection is useful when two different loop zones need separate outputs, such as free-exit and reverse, or presence and pulse functions.
No. MATRIX-S is the single-loop version. MATRIX-D is the dual-loop version and should be selected only when two loop inputs are needed.
Can this be used outdoors?
The detector is normally installed inside a protected operator or control enclosure while the loop wires are installed in the pavement or driveway surface.
