Alarm Port
The ALARM port provides a normally-on circuit and a normally-off circuit that
reverse their states in response to an alarm. This interface can be used to set off a
physical alarm.
Procedure
To use the ALARM port:
1. Connect a modular 8-pin cable to the ALARM port.
2. If the BitStorm 4800 is in a rack, dress the cable to the left and secure it to the
rail with a cable tie.
3. Connect the other end of the cable to your alarm monitoring system.
