Connecting External Alarms
To connect the external alarm contacts to the external alarm terminal block:
1 Route the external alarm input cables from the external equipment through
the cable gland on the external interface to the external alarm terminal block.
2 Using the details provided in Figure 2-29, connect the normally-open alarm
inputs from the external equipment to the external alarm plug.
3 Connect the alarm plug to the terminal block. Note the plug identifier and
using Table 2-18 inform the OMC operator which alarm code corresponds to
the external alarm that you have just installed.
Only the EP1 through EP17 plugs shown in Figure 2-28 use the
signal and ground alarm input pins. DO NOT connect EP1
through EP17 plugs to FC, TTL, 27V, VCC or DR connection
pins, or you can cause serious damage to the system.
Figure 2-29: External Alarm Plug
Inputs from external alarms should be normally open. When the
external contacts close, the Micro BTS sends an alarm to the
OMC.
