4.6 The SmartLoop/PSTN board
The SmartLoop/PSTN board allows the SmartLoop fire control panel to use the land line (PSTN). It
manages (and monitors) 2 lines and uses the most widely used reporting protocols (SIA, Contact ID,
etc.). It has an 8-slot audio memory for up to eight voice call messages. Completely managed by its
on-board microcontroller, it generates emergency calls in the event of CPU fault, and also any alarm
calls triggered during the CPU fault.
