POLITEC SANDOR SMA WS 415 4-Ray Double Optical Barrier 4TX and 4RX H 150 cm. 3-6V 19Ah batteries included.

The SANDOR SMA WS barrier line consists of a pair, namely a TX column and an RX column. The new self-optical recognition electronics can manage 2 to 6 lenses, all with double lenses and with SMA technology. 
The latest-generation electronic components have made it possible to obtain ever better results in terms of both reliability and performance, thanks also to the reduction in consumption, a battery life of up to 36 months is guaranteed, which may vary depending on the number of rays placed in the columns. The synchronism is optical, while for obvious absorption reasons, there is no thermostation, which reduces the range between TX and RX to 50 meters, in order to avoid possible false alarms in case of particular weather conditions. Through the dip-switches, it is possible to program the functions of OR/AND, crossing speed and activation of the disqualification due to fog. The alarm and tamper signal are given by two separate outputs to be connected to the most common radio transmitters on the market, housed inside the RX columns. The tamper alarm in the TX column is transmitted to the receiver optically. The two columns that make up the pair of the SANDOR SMA WS barrier with 2 or 3 rays, are compatible with the PARVIS SMA WS 2+2 or 3+3 barrier.
