Table 5.2.3
Maximum Detector Quantity & Cable Length for KFDO-CS-Ex 1.51P/2.51P
1.
If the circuit length is limited due to capacitance or inductance, (e.g. 1.3km (C)), then
the difference in cable length to that limited by resistance can be used on the non-
hazardous side. I.e. circuit length is from the isolating repeater to the EOL when the
length is limited due to cable capacitance/inductance, or from the F08's terminal
through the isolating repeater to the EOL when the limit to due to resistance.
2.
Cable resistance shown is for the complete circuit, i.e. both cables in the pair. The
value of 34
Ω
per km (return) is used for 1mm
2
.
3.
The maximum resistances shown for the fire wire circuits must include both cable and
fire wire (see Table 5.2.2 and associated Note 2).
4.
The letter in ( ) after the cable length, and the value in ( ) under the cable length
specify which parameter out of capacitance (C), inductance (L), and resistance (R)
provides the limitation, and what the limiting value is.
5.
The (m) after a detector quantity indicates the maximum quantity allowed per circuit.
