Optex, SL-350QFR-BT, 100m Photo Beam for Beam Towers with Wireless Model

The SL-350QFR is a 100m battery-powered outdoor active infrared (AIR) beam set which is designed for perimeter security. The Quad beam set is completely wire free and can be quickly installed in remote or hard-to-wire areas. It also features four selectable channels making it easy to stack in beam towers. Please note the EE1216 is sold separately.

Easy Alignment Tools

A perfect alignment between transmitter and receiver is key to optimise the operation of the active beams. To make the optical alignment easier, the SL-350FR chassis features vivid yellow colours to be seen from the distance. Additionally the "Sniper Viewfinder", a telescopic lens magnifying twice is fitted inside the beam.

Weather Resistant

IP65 rated, the SL-350QFR housing has been designed to resist against both water and dust. The two hoods featured on the front cover are positioned over the upper and lower beam to prevent frost from attaching to the cover and potentially affecting the signal power. The housing is made of UV resistant polycarbonate material to avoid deterioration caused by ultraviolet rays and maintain the a good transparency for the infrared beams over time.

Wireless Flexibility

Being battery-powered the SL-350QFR doesn't require any cabling at all which makes it a very flexible solution to protect hard-to-wire areas or temporary sites such as construction or event sites. The back-box is spacious enough to accommodate most wireless transmitters available on the market. Some wireless transmitters are available to purchase from us directly like the Ricochet-enabled BGR-01 or the Inovonics transmitters (some regional restrictions might apply).
