Optex AX-100TFRi iSeries Battery-Powered Photobeam Detector with Built-In Inovonics EN1941 Transmitters, 100' Detection Range

Secure long perimeters without the cost and complexity of hardwiring. The Optex AX-100TFRi photoelectric beam detector pairs robust dual-beam detection with wireless convenience to deliver reliable perimeter security up to 100'. Built on Optex's iSeries platform, this battery-powered photobeam includes long-life D‑cell lithium batteries (3–5 year typical life) and a built-in Inovonics EN1941 transmitter for fast integration into existing wireless alarm and monitoring systems.
