The Smart LineSL-350QFRi Battery Powered Quad-Beam Photoelectric Detector with Inovonics Transmitter from Optex offers detection up to a distance of 350' without requiring any trenching or wiring. The unit 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-350QFRi is compatible with the AX-TW200 line of beam towers for a clean, concealed, wireless mounting option. The SL-350QFRi is well suited for perimeter protection where labor costs or trenching is an issue. The iSeries SL-35OQFRi comes pre-installed with lnovonics EN1941 wireless transmitter, allowing even more time saved while on the job site. The EN1941 monitors the DQ circuit, tamper and primary alarm, while an included BCU-4 module monitors for low battery.
The sniper viewfinder telescope lens allows a high level of visibility and magnification for optical alignment work. Even at maximum installation distance, the viewfinder increases the probability of optimal alignment. Also, the IP65 weather protection allows the SF-QFR beam to be protected from interruption caused by insects, dirt, sand or humidity.
