The SmartLoop/2L package includes:
• A cable for the connection to the motherboard
• Two split ferrite cores for the loop output wires
• 5 anchor screws
• 5 spacers
5.1.2 The SmartLoop/NET board
The SmartLoop/NET board allows you to create a token-ring capable of managing 30 SmartLoop control
panels via a 3 -pole cable.
The network must be wired as a ring network with a maximum cable length between each panel of 2000
metres, in this way, the network will be fault tolerant (HorNet technology). Using a supplementary 2-pole
cable (5 poles in all), you can create a protection ring which can pass alarm conditions, coming from a fire
control panel with microprocessor fault, through the ring.
