AlEx - Alarm Extender

The AlEx (Alarm Extender) device is a telecontrol sys-tem that transmits local alarm signals via its G.703 64kbit/s interface to a remote alarm controller unit, which outputs the alarm via relay contacts. It enables to manage and supervise alarm systems, fire detec-tion systems or similar devices via parallel I/O ports.

AlEx offers 8 alarm inputs and 8 output contacts and an integrated transmission link monitoring function.

Additional two NOC‘s (normal open contact) are able to signalize state of G.703/64k line, local and re-mote device.

The Alarm Extender (AlEx) can also be used to ex-pand number of I/O ports of a modular IP Security Access Device (I-SAD 19”).
