Intrusion detector SL-200QDM/350QDM/650QDM

photoelectricinfrared

The SL-200QDM is a 60m outdoor active infrared (AIR) beam set, wired designed for perimeter security. The Quad beam set features four selectable channels making it easy to stack in beam towers as well as dual modulation and power auto-adjustment to provide a highly reliable signal transmission between receiver and transmitter even when exposed to strong sunlight or harsh weather conditions. Easy alignment A perfect alignment between transmitter and receiver is key to optimise the operation of active beams. To make the optical alignment easier, the SL-200QDM chassis features vivid yellow colours to be seen from the distance and the "Sniper Viewfinder", a telescopic lens magnifying twice the distance inside the beam. A sound gauge fitted in the receiver validates the accuracy of the optical alignment. For the fine tuning, the SL-QDM transmitter and receiver are both fitted with five LED to indicate the level of the signal received from the transmitter ranging from poor to excellent. Weather resistant IP65 rated, the SL-200QDM 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 good transparency for the infrared beams over time. Additionally, the beams are fitted the light disturbance compensation circuit differentiates the beam signal from other external light sources.
