Pair of outdoor photocells SLIM fixed 8° for connections via nice Bluebus, burglar-resistant metal body Nice EPSAB Safe: D type device according to specification EN12453 which allows to pick-up obstacles on the optical axis between transmitter (TX) and receiver (RX). Using the fototest function it is possible to achieve class 2 safety fault according to specification EN 954-1. Cutting-edge technologies: antiglare circuit which eliminates possible sunlight interference. Practical: 8° angle of reception. Resistant and vandal-proof: ABS body resistant to weather conditions, available also in burglar-resistant version with metal shell (Mod. EPSAB). Nice BlueBUS technology: available with the BlueBUS system, which allows an easy connection to the control unit of all devices with only two wires, by simply connecting them in parallel and selecting the jumpers for addressing according to the needed function. The system acquires automatically the devices connected to the BlueBus network. Automatic synchronization between multiple photocell pairs in order to avoid other possible interferences between the devices. IB interface: allows the connection of proximity readers with Nice BlueBUSs technology to control units having terminals for traditional contacts.
