III STARTUP OF THE DIGITAL UNIT
1. POWERING OF THE FG-SYS DIGITAL UNIT
When all of the cables - leader cables, jumper cables, sense cables, power supply cables - and the
accessories – diversion boxes, end termination plugs- are connected, switch the FG-SYS Digital Unit
ON.
When the digital unit is turned on, it goes into TEST mode: an audible alarm sounds and a luminous
witness glows red. The luminous witness turns to green while the digital unit is under TEST, shown on
the display.
The digital unit tests one circuit after the other. Three circuits of sense cables are available on the
digital unit. In the majority of cases, only one circuit is used. The display indicates the length of each
sense cable, as well as the overall length of the circuit.
Once the test is finished, the digital unit passes into MONITORING mode:
