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.
