By pressing the "ok" key each single detector can be stored in the FCP programming, by pressing "all ok"
all connected devices will be stored in the FCP flash memory simultaneously.
Checking of earth fault
A constant voltage must not be measurable between potential earth and fire control panel potential

In case of an earth fault this has to be localised by disconnecting single cables in the fire control
panel. Then the earth fault has to be removed. The supervision of an earth fault can be deactivated
by system parameter 13.
Measurement of loop voltage and current
Dependent of the used multimeter the voltage and the current will vary differently. This is caused by
the modulated protocol between the FCP and the loop devices. For the measurement of the current
the loop has to be separated on one side in the FCP and on the other side the current has to be
measured on the ML+ or ML- wire. At the same time the loop devices have to be in the quiescent
state. Decisive for a faultless operation is the fact, that all loop devices are supplied by a sufficient
voltage (17V). The voltage drop on the cable has to be calculated form the quiescent current and
the cable resistance measured under point 4.2.

The thresholds depend on the load resistance of the connected device inclusive the line resistance. This
total resistance can be ascertained automatically for each power output individually by pressing "calib."
F3. The software then calculates the thresholds for open curcuit and short curcuit. The resistance can
also be measured with a multimeter and typed in directly using the keyboard.
