POLITEC SANDOR SMA SL 415 Self-powered 4TX and 4RX dual optical 4-Ray Barrier - 10m range, h. 150cm

Miniaturized barrier, particularly designed and recommended for the protection of doors and windows, such as the spinar SADRIN but in a self-powered version. Interfaceable with the most common radio alarm transmitters on the market, thanks to the alarm and tampering outputs with N.C. contact controlled by bistable low-absorption relays. Easy installation and programming, thanks to SMA technology that, during the test phase, automatically recognizes the number of rays and their alignment with optical synchronism, followed by the walk test with functional verification of all rays. Each beam is always formed by a double AND lens, while the alarm can be programmed in single-beam OR with different intervention times or in random AND, interrupting at least 2 random rays. Depending on the standard or oversized heights on request, it is possible to insert from 2 double spokes, present on the CPU motherboard up to a maximum of 8 with flat cables of various sizes. The autonomy varies depending on the number of rays and the type of batteries used (from 12 months to 3 years). The low battery signal is given acoustically, during the interruption of the rays. If the battery is completely discharged in an unattended condition, an alarm is generated because the micro relay has positive safety.
