ISOLATING REPEATERS (CONTINUED)
Notes:
1. The KFDO-CS-Ex 2.51P is two KFDO-CS-Ex 1.51P isolators in one package.
2. The resistance quoted in Table 5.2.2 for fire wire is per wire, thus the circuit resistance of
the pair is twice that amount.
3. The FW68 and FW105 fire wires are not currently listed as IS.
4. The capacitance and inductance of the T54B and the T56B/Z55B are negligible.

CIRCUIT WIRING WITH ISOLATING REPEATERS
Figure 5.2.1 shows the wiring of the approved isolating repeaters with F08.
Note:
Do not connect 15V MCPs onto detection circuits that are connected to the F08 through an
isolating repeater.
To use MCPs in an IS area, short circuiting MCPs (not 15V type) must be connected onto
their own circuit through a separate isolating repeater channel to F08. The circuit input type
must be programmed as type 1 (no AVF).
The number of detectors that can be accommodated on each IS circuit depends on the
detector type and the cable length. Table 5.4.3 shows the details for the different detector
types and different IS classifications.
