4.2.11. External-Alarm Inputs and Outputs
There are four alarm inputs and four alarm outputs. Each alarm output can be assigned
individually to any alarm at the Remote Unit. Settings need to be made via the ION-M
Master Controller. For details please refer to the corresponding chapter in the User’s
Manual of the ION-M Master Controller.
 Note: The manufacturer / supplier of this system assumes no liability for
damage caused by equipment connected to external outputs or by effects
from such equipment.
As accessory equipment the alarm kit is available to connect external devices to the
external alarm inputs and outputs. For the exact ID No., please refer to section 7.3
Spare Parts. Subminiature circular connectors series 712 with five and seven contacts,
which are contained in the alarm kit, can be ordered directly from the Binder Connector
Group, the manufacturer, or indirectly from CommScope.
For the location of the external-alarm inputs and outputs see figure “Connector
Flange”.
Optocoupler-Alarm Inputs
With the external alarm inputs it is possible to monitor the status of connected devices,
e.g. a UPS, via software. All alarm inputs are normally high (5 V) without connection.
The polarity (high/ low) can be set via the software at the Master Unit (for details please
see corresponding software manual).
