Parvis SOLAR SMA marks a further evolution of the range as it exploits the alternative energy of the sun. The barriers are equipped with a mini solar panel applied to the upper part of the display. It ensures that the batteries inside the columns are constantly charged, so that they can power the circuitry and all the optics. The barriers are of the low-consumption type, with 2 to 6 beams, optical synchronism and a maximum range of 50 metres. They must be interfaced with the alarm control unit using conventional radio system transmitters available on the market for alarm and tamper signalling.
The rechargeable batteries are guaranteed to last at least 3 months, taking into account the periods of absence of sunlight. If the battery wears out completely, an alarm is generated as the micro-relay is a positive security device. The low battery signal and disqualification output can be remoted through dedicated outputs on the control board.
PARVIS SOLAR SMA 2+2 or 3+3 can be interfaced with the SANDOR SOLAR SMA pair with 2 or 3 beams in TERMINAL mode.
