The AX-TFR Series (100- and 200-foot models) from OPTEX is a revolution in the perimeter security industry, offering a significant cost-saving alternative to traditional hardwired systems. No trenching is required, drastically reducing installation costs. The AX-TRF Series is available in two versions: A wireless-ready option with a multi-functional back box that is compatible with most manufacturer's wireless systems, and a wireless version complete with Inovonics EchoStream transmitters. Included in both versions are four 3.6V batteries, with an average lifespan of five years on the 100-foot model and three years on the 200-foot model. The AX-TFR Series is perfect for setting up a perimeter at job sites, remote locations and areas where trenching is not an option.
