“ABSOLUTE PLUS” Mini-Midi range are barriers of Absolute Family, the only barriers for perimeters protection that combines in one unit active bi-directional and active microwave technologies. The system grants, if properly installed,  the best conditions for the alarm detection, combined to a minimal false alarm rate or interference. Every Absolute system is composed by 2 pillars : one master pillar (called also transmitter or TX) and one relay pillar (also called RX or Receiver). The functioning of the barrier is based on a logic of a time-window opening when an pre-alarm of one of the 2 technologies is generated (normally from the microwave). If in this time window arrives the confirmation from the second technology, the system generates the DT Alarm. IMN50 and IMN80 are configured to have a detection range of 50 and 80 meters, for a standard height of up to 4mt.
