25.6 MDF CHAMP100 cable connector
This section describes line number and color designations, and the pinning of the
CHAMP100 MDF cable.
25.6.1 Cable colors
The following designations are used for the cable colors:
Table 25 Cable color designations
Note 1 — The input alarms are implemented using normally
closed (NC) relays (that is, closed when no power is applied).
The output alarms are indicated by a short circuit.
Note 2 — The following applies for the external CO alarm
signals:
• maximum current drain is 100 mA
• voltage is determined by supply voltage (−48 V)
• BATRET voltage of the alarm wire is different from the
power BATRET voltage (due to the voltage drop in the
feeding cables)
Nokia strongly advises adding extra in-line 100 mA fuses in
the BATRET connections to comply in a safe way with the
maximum current drain of 100 mA in the BATRET wire.
