In retrofit applications where existing wiring will be used,

do not exceed the SLC resistance and capacitance limita-

tions listed above. All conduit and conductors must meet

NEC, NFPA-72 and any applicable local code requirements.

See Figure 7-4 for existing shielded cable termination. Op-

tionally, the PC line can be installed in a separate conduit

as shown previously, thus allowing the PC line to use

twisted, unshielded wire.

Note: All new RCUs are shipped from Kidde with their

address set to 000. This address is reserved for

unregistered devices and cannot be used as a reg-

istered address. The unaddressed devices must

be connected to the RX/TX Module one at a time

in order to address them. Otherwise devices may

be pre-addressed or multiple pre-addressed loop

devices may be connected to the RX/TX PC line

at the same time using the hand-held device pro-

grammer (P/N 74-200013-001) .

Refer to Table 5-2 for a list of the types of allowable con-

figurations that can be selected, along with the respective

jumper settings for those configurations. As described in

this chapter, the PC line can be configured in Style 4, 6

or 7. Each Style is represented in Figures 7-5 through 7-8.

Style 4 configurations allow T-tapping. T-tapping is only

limited by sound installation techniques.

Figure 7-5. Style 4, RX/TX PC Line Connections

In the Style 6 wiring configurations, the RX/TX automati-

cally transmits data and power bi-directionally when a break

in the PC line wiring occurs. If the break is in a single con-

ductor, all loop devices will remain fully operational. For

Style 6 PC line connections, if a PC line open trouble is

encountered, use the system reset switch on the display

and control board to reset the PC line to normal once the

fault is corrected.
