The Optex SL-350QFR is a battery operated quad beam photoelectric detector featuring a 350 ft. detection area.

Optex expands on its industry leading outdoor battery-powered intrusion line by adding the quad beam SL-350QFR, a 350 ft. battery-powered photoelectric detector requiring no trenching or wiring. Because of this, integrators and dealers can offer a significant cost saving alternative to traditional hardwired systems, while end users will benefit from less downtime to business operations during install. The iSeries SL-350QFR includes a multi functional backbox that accepts most manufacturers wireless transmitters, and comes with four batteries per set, with the option of expanding to eight for up to 10 years of battery life. In addition, the SL-350QFR is compatible with the AX-TW200 line of beam towers for a clean, concealed, wireless mounting option.The SL-350QFR is the perfect solution for perimeter protection where labor costs or trenching is an issue.

Revolutionary Design

Optex offers a less expensive and more efficient solution with SL-350QFR. Typical perimeter systems require expensive trenching or much time for installation. Expensive wire conduit runs and concrete work is unnecessary, allowing installers to save time and money.

Long Battery Life

When using the included LSH (3.6V, 13Ah) batteries by SAFT, users can expect approximately 4 years (max. 10 years) of long battery life.


The SL-350QFR, wireless-ready, battery operated photoelectric detectors are designed to work with most manufacturer's wireless transmitters, and the back box has enough space to accommodate them. They are easily deployable and adaptable to any control systems currently installed.
