EXTERNAL ALARM INPUTS AND OUTPUTS
There are four alarm inputs and four alarm outputs. The alarm outputs (open
collector output 5 V / 1 mA) are normally low. In case of an alarm they are high active
(5V). They can be used to monitor alarms with an external alarm indicator. Each
alarm output can be set individually to any alarm at the Remote Unit. For details
please refer to the according chapter in the software manual of the Master Unit.

damage caused by equipment connected to external outputs or by
effects from such equipment.
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 (5V) without
connection.
The device to be monitored must be connected so that the alarm contacts (contact
on the right is always GND) will be closed in case of an alarm (I max = 8 mA). The
alarm inputs are potential-free with common ground.
For the location of the external alarm inputs and outputs refer to figure 6-1
Connecting board. Settings have to be done via the MMR Master Controller and are
described in the according software documentation.
