Installation, Wiring & Compatibility FAQ

Quick answers to common questions about voltage matching, relay outputs, and direct replacement on existing door operators.

Will these sensors work with my existing commercial door control board?

Yes. All our sensors utilize standard Form-C dry contact relays (providing Common, Normally Open, and Normally Closed terminals). As long as your door controller features standard terminal inputs for external trip devices (such as Safety Edge, Photoeye, or Push Button inputs), our units are 100% plug-and-play compatible.

Most active radar and light curtain units accept universal low-voltage inputs (12–24V AC/DC), which can be powered directly by the 24V accessory output on modern door controllers. For line-voltage setups, our loop detectors are available in dedicated 100–240V AC versions to eliminate the need for external power supplies.

Yes. Both the IWD-24D and RD79-6M radar units incorporate directional filtering and target size evaluation. They can be set to ignore cross-traffic and walking personnel, opening high-speed doors only for approaching industrial vehicles to preserve indoor climate and energy efficiency.

Every shipment includes a comprehensive pinout schematic, color-coded terminal block labels, and heavy-duty angle-adjustable mounting hardware. If you are retrofitting an older door brand, send us a photo of your control board’s wiring diagram for tailored connection instructions.
