Sl  Qfr

Product Details

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 LSH-20 batteries are 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-350QFR 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).

FAQs

Yes, all our external beams include pole mounting kits as standard.

The key success of a reliable active infrared intrusion system relies on the accuracy of the beam or beam tower alignment. If the transmitting ‘beams’ and the receiving ‘beams’ are not well aligned, there is a risk of severe environmental interference from fog and sunlight, even more so if the beams are 100m or 200m apart.

When installing beam towers around a perimeter there is the tendency to think that the towers should be at a 90 degree angle from each other. Actually, a 90 degree angle can restrict the view for the signal due to the tower extrusion lip. Our technical team recommends mounting the beam towers at a 45 degree angle on the ground, this allows the beam mounted inside the tower a clear view and gives the installer some flexibility for alignment.

If you are using a floor mount enclosure, the same principle applies: you should dig a 45 degree angled square in the ground to install the ground bracket. For a more efficient method, our tech team highly recommends using theTW SSL an adjustable mounting plate specifically designed for our Smart Line Beam series. The Smart Line beam can be fixed on to the TW SSL then the plate can be clipped in to the beam tower. Using this method, alignment can be easily facilitated by simply adjusting the plate up or down in the grooves to set it at the right height.

The beams can operate between 10.5vDC to 30vDC. When connecting to an intruder system, 12vDC will be sufficient. If however, you’re using a heater unit (HU-3) you will need a 24vDC supply. Our wireless beams will need 2 or 4 3.6v lithium batteries.
