Intercabling Connections
Alarm Intercabling
Cabinet equipment alarm connections are made between the RF Cabinets
and the Environmental Alarm System (EAS/EAS2). The location of the
alarm connection for the RF Cabinet depends on the type of RF Distribution
System (RFDS) that is being used.
■ 800 MHz Duplexed and Duplex Hybrid Expansion RFDS
(0182020V06 and earlier) — The alarm connection on the Main RF
Cabinet is on the Main RF Cabinet junction panel and is labeled ALARM.
The alarm connection on each Expansion RF Cabinet is located on the
RFDS Power Supply tray.
■ 800 MHz GEN 4 Duplexed RFDS and 900 MHz Duplexed RFDS —
The alarm connection on the Main RF Cabinet and expansion cabinet(s) is
located on the Rx Multicoupler tray on each cabinet.
■ Cavity Combining RFDS — The alarm connection is located on the
RFDS Power Supply tray and is labeled ALARM.
Alarm Intercabling Procedure (General)
Perform alarm cabling from the EAS/EAS2 to RF cabinets (RFCs) as
follows:
1. Make certain an adequate quantity of RJ45-to-RJ45 cables (P/N
3084225N42) is available. Each RF cabinet requires one cable.
2. Refer to Table 4-16. Noting the type of system being cabled, proceed
as directed in Table 4-16.
Alarm Intercabling Procedure (For Systems
Using More Than 3 RF Cabinets)
Alarm wiring for the Main RF Cabinet and Expansion RF Cabinets #1 and
#2 terminate directly to the EAS/EAS2 rear panel as described above.
Alarm interface for Expansion RF Cabinet #3 is facilitated by Modular
Adapter (PN 2882174W03), which breaks-out various signal pairs from
EAS/EAS2 punch block 2 (USER ALARM/CONTROL) into six modular
connectors.
Connect the alarm cable from Expansion RF Cabinet #3 to the modular
connector designated as “EXPANSION RF CABINET #3”, as shown in
Figure 4-17.
