PB HARRY is the new expansion satellite for the PB Hermione control units. It can manage 8 wired inputs and 24 sensors from the PB Elettronica Wireless line. The board is also equipped with 2 relay outputs and 6 Open Collector outputs. The wireless part uses simultaneous dual band detection technology to defend the system against alarm blocking in accordance with the EU regulations in force. The input configuration is managed through the programming software of the Hermione control unit and does not require manual teaching, not even for the wireless sensors. In fact, the sensors in the PB Elettronica Wireless line are supplied with a dedicated serial number to simplify the configuration. It is possible to connect up to 4 PB HARRY expansion units to each Hermione control unit (to manage a total of 96 wireless sensors). Harry maintains the multi-balancing concept, and it can therefore interface to sensors already connected to other control units without changing the existent balancing. Harry monitors the connected radio sensors and communicates faults and low battery status.

Operational features
Bus expansion for radio inputs and for wired inputs and outputs. The radio inputs allow a wide range of wireless sensors to be connected to the Hermione control unit, making them individually identifiable.
