Alarm Installation

General alarms can be monitored in several ways depending on how the system is configured. In systems with MX-ONE Classic (7U chassis) and MGU board, the simplest way is to use the alarm input on the DC/DC-board and configure the MGU board.

When many external alarm shall be monitored or when system is not equipped with MGU board, an ALU2 board can be used.

If more in- or out- signals are required, the number of ALU2 boards can be increased. Alarm indications are normally transferred to the PBX operator consoles when using ALU2.

In systems with MGU boards, the system can supervise several alarms, both external and internal.
