A.3.5 Label for External Alarm Cables
This topic provides information on labels and example of labels for external alarm cables.
The external alarm cables are connected to the first cabinet that provides power supply of each
row. Labels attached to the first cabinet must indicate the access terminal distribution for the
devices. Labels are not required to be attached to the device unless it is required. Here, only Area
2 of the label should be filled in.
Table A-9 describes the information on the label for the external alarm cable.

Meaning Example
MN MN: Cabinet
number.
l M: Cabinet row, numbered A to Z from front to back.
l N: Cabinet column, numbered 01 to 99 from left to right.
For example:
A01: Cabinet in row A and column 01.
NOTE
Generally, the preceding numbering method helps identify the position of a specific cabinet. If two cabinets
are installed back to back, the front direction of the cabinet must be specified. Hence, the numbering method
MNO is used. "O" indicates the direction of the cabinet, which can either be "A" or "B." This numbering
method is also used for the cable labels described in the following sections.
You need to fill only a part of the text area because the label on the alarm cable provides basic
information. It is recommended you reserve the entire length of the label. Do not cut off the
blank area.
Figure A-55 shows a label on the alarm cable. "A01" indicates that the alarm cable is connected
from the first cabinet to the cabinet in row A, column 01.
