VII.3.S. EX200 (ALARM) ALARM MODULE
The DS200 alarm card is a module, on which there are 32 channels, which communicates
with the CPU directly through the serial channel, and which does not require the PCM
signals.
There are totally 8 RJ45 connectors on the card. The first of those is used to provide an
output port for 4 system alarms on the card. The other 7 connectors, on the other hand, are
the input ports that let 28 different alarm signals into the exchange. 48-volt alarm signals are
detected at the alarm input ports.
The alarms present at the 4 output ports are as follows:
Alarm output no Indication of the alarm
1 Extension fault
2 The PRI connection is broken.
3 The redundant CPU is in use.
4 Inactive card present
There is also an alarm pane in order to present the signals visually, which are at the alarm
ports. That alarm pane can be customized to fit several applications. Below is the picture of
that type of an alarm pane.
The alarm pane must be powered with 12 VDC power supply. There is a special power
module for that purpose, which converts the 48 VDC power output of the exchange (the
battery connection point) to 12 VDC.
