TABLE 9.4.5
MAXIMUM DETECTOR QUANTITY & CABLE LENGTH FOR 4 TERMINAL
REPEATER ALONE
Notes
1.
Circuit lengths quoted are from the isolator to the EOL. The length quoted is the
maximum for the corresponding quantity of detectors.
2.
Cable resistance shown is for the circuit, ie. both cables in the pair. The value of 34Ω
per km (return) is used for 1 mm².
3.
The maximum resistances shown for the fire wire circuits must include both cable
and fire wire (see table 9.4.2 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.
